Specific objectives of the field program included: 1) Establish present patterns and potentials of wildlife uses in the West Creek watershed, with primary emphasis on goat, moose, and bear populations in the area of the proposed reservoir. 2) Describe and map the associated flora and relevant terrain features which define wildlife habitat and influence use patterns. 3) Consider and evaluate possible impacts on wildlife of the pro- posed hydroelectric development options. 4) Recommend appropriate mitigation measures. METHODOLOGY The survey of wildlife resources and habitats conducted in the West Creek drainage system between 23 July and 27 August 1981, included (a) on-the- ground examination of much of the vegetated portion of the impoundment area and watershed above and below the proposed development site to define the major habitat types present, (b) helicopter reconnaisance, telescopic examination of the landscape, and the use of aerial photographs to extrapolate the recognized habitat types to areas not examined on the ground, (c) observation of animals and sign to estimate their distribution and relative abundance within the watershed, and (d) interviews of indi- -1- vidua1s for additional knowledge of wildlife in the West Creek area. Wildlife surveys and vegetation assessments were conducted by Dr. O. Charles Wa11mo and Mr. Steve Jacoby, respectively. By foot travel, thorough coverage was obtained of: 1) Most of the area within the watershed east of the longitude of the dam site, 2) Most of the valley bottom from the dam site to the origin of the main stream of West Creek, 3) Lower slopes of the northeasterly side of the valley from the dam site through Sec. 1, T27S, R59E, 4) The elevation range of 2500-4500 feet in Secs. 5, 6, 8, and 9 of T27S, R59E, 5) The elevation range of 3000-4000 feet in Secs. 19, 20, 29, 30, and 31 of T27S, R59E and Sec. 31 of T28S, R59E, and 6) Secs. 28, 33, and 34 of T26S, R59E. Mountainsides on the southwesterly side of the valley, including the west side of the major, glacial tributary creek (Le., Secs. 13, 24, 25, and 26 of T27S, R59E), were not covered afoot but were subjected to intensive binocular and telescope surveillance on several days. All of the watershed area, except 3-4 mi2 of ice cap on the northwest end, was reconnoitered by helicopter, landing at numerous locations in the alpine and in forest openings to define surrounding vegetation types and look for wildlife sign.

HABITAT TYPES For simplicity and uniformity, major vegetation types were considered as general wildlife habitat types. A generalized distribution of major vegeta- tion types is presented; detailed analysis of understory plant associations was considered to be beyond the scope of this project. For purposes of discussing wildlife distribution, the vegetation/habitat types identified within the West Creek drainage are referred to as follows: -3- Conifer forest Riparian shrub Sedge marsh Upland shrub Tundra Barren rock Glaciers For mapping of wildlife habitat types, the distribution was simplified by combining all conifer types and bottomland types (Figure 1). Vegetation classifications are differentiated, however, on Figure 2. Conifer Forest The Sitka spruce (Picea sitchensis) -Western hemlock (Tsuga heterophylla) forest type is found generally throughout the West Creek system, representing the only vegetative type of any significant commercial value within the confines of the study area. Within the upper three miles of West Creek, conifer forest is found on the steep slopes rising from the basin floor, typically extending in bands and patches up to 2000 feet on slopes ranging from 60 per cent to nearly vertical. Within the lower four miles of West Creek, the spruce-hemlock forest is the major vegetative cover on the basin floor and extends throughout all eleva- tion zones up to 2000 feet. Old growth (+150 yrs.) as well as even-aged young growth exist within the stand. Continual disturbances, due to the steep terrain allowing for wind and avalanche activity, promote new stand development. Logging in the mid-1960's removed approximately 180 acres of spruce and hem- lock timber growing on the north side of West Creek, approximately one and one-quarter miles westward along West Creek from Dyea. Due to the surface disturbance by the "cat logging" that was done within the cutting unit, alder is competing heavily with the spruce and hemlock regeneration at this time. -4- Associate tree species within the spruce-hemlock forest include mountain hemlock (Tsuga mertensiana), Western paper birch (Betula papyrifera) and black cottonwood (Populus trichocarpa). Mountain hemlock is sparsely distributed below 1200 feet, but combines with Sitka spruce to make up the overall forest canopy in higher elevation zones. Paper birch occurs on the Taiya River floodplain and on the low, drier east and west-facing slopes of the drainage. Black cottonwood is typically mixed with Sitka spruce along the glacial outwash areas and branch channels of West Creek proper, constituting a riparian woodland habitat. Distinct from the typical spruce-hemlock association, an approximately 55 acre stand of eighty year old Sitka spruce occurs within the impoundment area at the confluence of West Creek and a large glacial tributary. The dense stand is confined to a poorly-drained elevated bench, slightly above the local elevation of West Creek. Due to the poor drainage character- istics, the site productivity is relatively poor and the timber is small. Common understory plants associated with the spruce-hemlock and spruce forests throughout the West Creek area include: Devil's club (Oplopanax horridus) Stink currant (Ribes bracteosum) Thimbleberry (Rubus parviflorus) Salmonberry (Rubus spectabili~) Blueberry (Vaccinium spp.) High-bush cranberry (Viburnum edule) Red-berry elder (Sambucus racemosa var. arborescens) Located on the southeast-facing slope above the Taiya River is a relatively small band of lodgepole pine (Pinus contorta). Pine is generally found between 800-1300 feet elevation, but can occur in most elevation ranges in the Skagway area. Associated species include birch, mountain hemlock, spruce, alder and occasional cottonwood. Soils are considerably drier and granitic outcroppings are common. -7- Riparian Shrub Dense stands of alder, alder and willow, and willow (grading in this order from better-drained to wettest sites) occur along West Creek and in the floodplain. The alder vegetation type, including-Sitka and red alder (Alnus sinuata and A. rubra), comprises a significant component of the vegetative cover within the upper third of the West Creek drainage. This includes the area ranging from the glacier terminus at the head of the West Creek eastward along the creek floodplain for approximately three miles, where the conifer forest begins to dominate. The alder within this described route of glacial retreat occurs in thickets, creating a very dense overstory shrub canopy. Willow (Salix spp.) is a common associate shrub species in wetter soils, and black cottonwood and Sitka spruce are commonly found where soils are more mature. Beneath the alder canopy there is often a well-developed fern and grass layer, as well as an association of herb and shrub species. The most common woody plants associated with this vegetation type include: Devi1's club Rusty menziesia (Menziesia ferruginea) Stink currant Thimb1eberry Salmonberry Willow Red-berry elder Sweet gale (Myrica gale) High-bush cranberry Willow shrub thickets occur within the more poorly drained areas found on the north side of West Creek beginning approximately one and one-half miles down stream from the glacier and extending in patches about two miles east- ward. Due to the nature of the occurrence of willow in relation to patterns of drainage, willows converge with the alder type in better-drained soils and with the sedge marsh type in the wettest areas. -8- Sedge Marsh Sedge marsh vegetation occurs in proximity to riparian shrub sites where drainage is poorest. Although the vegetation is somewhat variable, the most common association includes sedges, rushes and grasses. Thick mats of sphagnum mosses also occur. Upland Shrub Alder and/or willow occur on slide slopes and mountainsides up to 2500 feet elevation generally, and to 3000 feet in some tributary drainages. Above 2000 feet willow is predominant, and in some areas, mostly at higher eleva- tions, blueberry predominates. Tundra The transition from forest or upland shrub to alpine tundra occurs generally between 2500 and 3000 feet. In this ecotone, stunted mountain hemlock, subalpine fir and, occasionally, ~itka spruce occur in small clumps inter- spersed in dwarf shrub/herb communities. Above 3000 feet dwarf shrub/herb communities (e.g., Vaccinium, Salix, Lupinus, Antennaria, Ranunculus, Potentilla, Heuchera, Geum, Silene, etc.) give way to predominantly heather communities (Cassiope, Phyllodoce, Empetrum, Cerastium, etc.). Alpine tundra is discontinuous above 4000 feet and essentially absent above 4500 feet. Barren Rock Most of the terrain above 4500 feet and slide areas below the glaciers are largely barren of vegetation. Extensive sandy-gravelly areas of decomposed granite occur on both sides of the valley above 3000 feet. The barrenness of this zone is due primarily to disturbance (slides and soil instability) and/or the long period of snow cover. Drift-snow fields and avalanche run- out snow fields are common. Glaciers There are about 12-13 mi 2 of glacier within the West Creek watershed. At higher elevations it is difficult to distinguish glacier and current snow fields. -9- WILDLIFE SPECIES Mountain Goat (Oreamnos americanus) Mountain goat sign was encountered in all of the terrain covered above timber line on both sides of the valley. On the basis of density of sign (tracks and feces) the most heavily used areas appear to be Secs. 5 and 6, T27S, R59E, in the range of 2500-4000 feet elevation on the southwest- facing, northeast side of West Creek and in Secs. 13, 24, and 25, T27S, R58E in the range of 2500-3500 feet on the south-and east-facing, west side of "Glacier Creek" (the larger glacial tributary entering West Creek in Sec. 13, T27S, R59E). In the latter general area, 7 nannies, 6 kids, and one yearling were observed on 7 August and 3 nannies, 3 kids, and one unidenti- fied adult on 8 August. Adult males were observed in Sec. 36, T27S, R58E and Sec. 27, T26S, R58E. An area resident (Skip Elliott) reported having seen "lots of goats" in Secs. 35 and 36, T26S, R58E. In our survey, goat tracks and fecal droppings were most abundant in a steep area of sandy-gravelly decomposed granite in the range of 3000-4000 feet elevation on the east side of Sec. 6, T27S, R59E. In the valley bottom below this area, on the northeast side of West Creek, goat hair was found in a willow thicket. During winter and early spring, goats in this region commonly descend to steep, cliffy forested areas to forage and occasionally descend to the valley bottoms. Valley bottoms cannot be considered essen- tial habitat, however, though forested mountainsides often are. A small number of area residents hunt mountain goats in the West Creek drainage. Two (Tim Hendrickson and Roy Nelson) report bagging a goat in 1973 in Sec. 8, T27S, R59E. Two others (Rocky Lane and Thor Hendrickson) have hunted in the Mt. Yeatman area within the West Creek watershed and the Face Mountain area south of West Creek. Moose (Alces alces) Our observations, confirmed by the experience of local residents,-indicate that there are no moose in West Creek. However, the valley bottom, from the -10- proposed dam site upstream to the head of West Creek proper, contain perhaps 2 mi 2 of marginally suitable moose habitat. Sitka Black-tailed Deer (Odocoi1eus hemionus sitkensis) West Creek is about 60 miles north of the northern limit of distribution of Sitka black-tailed deer as defined by Alaska Department of Fish and Game. There still are occasional reports, however, of black-tails in the Skagway- Dyea area. In August 1981, one was seen (by Roy Nelson) at the Dyea (Taiya River) bridge south of West Creek and deer tracks "headed north" were reported to have been seen two days later (by Tim Hendrickson and Roy Nelson) at Finnegan's Point and Canyon City north of West Creek. Periodically excessively deep snow limits the northward extension of deer range in southeast Alaska. _There is no deer population in West Creek currently and any deer that might colonize there would not persist long. Black Bear (Ursus americanus) Sign of black bears, consisting of fecal deposits, tracks, recently-used trails, and evidence of foraging on ~egetation was encountered generally in all forested areas and throughout the riparian shrub and marsh zones from the mouth of West Creek to the terminus of the glaciers at the valley head. 2 The occurrence of fresh sign over an area of about 5 mi and a linear distance of 6 miles indicates that several black bears inhabit the West Creek drainage. An area resident (Skip Elliott) considers the vicinity of the upper end of the c1earcut and the proposed dam site to be most heavily used. This con-, forms with our observations in that general area on both the north and south sides of the creek. We found equivalent densities of sign, however, in the vicinity of the cabin midway up the creek and below the terminus of the smaller valley glacier. The local resident mentioned above reported having seen bears in the vicinity of the cabin and the upper end of the c1earcut. Other residents reported -11- bears seen in the clearcut and in the vicinity of the proposed powerhouse site. One area resident (Rocky Lane) reported killing a male in the fall of 1980 in Sec. 11, R58E, T27S. Another resident (Thor Hendrickson) was reported to have killed a black bear "near Mt. Yeatman" in fall of 1980. We saw no bears during the wildlife survey. Tracks of a sow and cub were found near the terminus of the smaller valley glacier. Contents of all scats seen throughout the drainage area indicate that succulent vegetation and berries were predominant foods of black bears at this season. Brown (grizzly) Bear (Ursus arctos) Fresh tracks of a large brown bear were seen on 5 A~gust at 3200 feet eleva- tion just north of the center of Sec. 8, T27S, R59E, in the alpine tundra type. A scat of brown bear, also in the alpine tundra type, was found at about 3500 feet elevation in the northwest quarter of Sec. 29, T27S, R59E. Contents of the scat were principally crowberry leaves and fruit. An area resident (Don Corwin) reported that an acquaintance (Sherell Stead) saw a brown bear in 1979 near the terminus of the larger valley glacier at the head of West Creek (ca in Sec. 35, T26S, R58E). Another area resident (Roy Nelson) reports having seen brown bear tracks leaving West Creek near the Taiya Slough every fall for the past 12 years. Joe Wallmo, a party to this investigation, saw brown bear tracks in 1978 on the north side of West Creek in the S.W. quarter of Sec. 7, T27S, R59E. Another area resident (Skip Elliott) observed and measured tracks in upper West Creek that fit the size of brown bear. The sign seen by us indicates that at least one or two brown bears currently include portions of West Creek within their home range. Wolverine (Gulo gulo) An area resident (Skip Elliott) reported having seen three wolverines in winter in the upper end of the valley. -12- Wolf (Canis lupus) No evidence of wolves was found by us, nor did we obtain any reports of wolves or wolf sign from others. Coyote (Canis 1atrans) We found feces of coyote in the c1earcut and in the alpine tundra at about 4000 feet elevation in Sec. 30, T27S, R59E. A coyote was seen on 1 August by Steve Jacoby, a party to this investigation, in the lower portion of the c1earcut. National Park Service personnel report seeing coyotes occasion- ally along the Taiya River above and below West Creek. They are reported (by Skip Elliott) to be less abundant now than in the winter of 1979-1980 following a high population of snowshoe hares. R. S. Fleming observed a coyote 4 October, 1981, in Taiya valley at edge of trees at south end of valley. Other Furbearers Feces of river otter (Lutra canadensis) were observed in the valley bottom about halfway between the dam site and the head of the river. Marten (Martes americana) have been reported near the cabin. Neither observations nor sign of least weasels (Mus tela rixosa) and mink (Mus tela vison) were obtained, but it can be assumed that they occur in West Creek. No evidence was found of beaver (Castor canadensis) within the West Creek watershed. Small Mammals Sign and/or observations of deer mice (Peromyscus sp.), least shrews (Microsorex sp.), porcupines (Erethizon sp.), and red squirrels (Sciurus hudsonicus) indicate that they are widely and abundantly distributed throughout the forested areas. No evidence of 1agomorphs was found within the West Creek valley, but varying hares (snowshoe rabbits) and sign were seen in the Taiya valley bottom below West Creek. Evidence of voles (Microtus and/or C1ethrionomys) was noted in bottomland shrub and marsh habitats. -13- Waterfowl No ducks, geese, or swans were observed in the West Creek drainage. Open water suitable for use by waterfowl is restricted to about 20 small ponds with a combined area of less than 5 acres in scattered, small areas of sedge marsh or willow/sedge marsh (Figure 3). For the most part, the unforested areas of the valley bottom is dominated by dense alder, alder/willow or willow thickets of low value for waterfowl. West Creek itself generally flows too swiftly for use by waterfowl. R. S. Fleming observed widgeon take flight from small pool in area above dam site, 3 October, 1981. Grouse Sightings and sign of blue grouse (Dendragapus obscurus) indicate that they are generally distributed throughout the forested portions of the West Creek valley and are more common in upland forests and along tree line than in the valley bottom. Ptarmigan (Lagopus spp.) sign was found in varying density in all portions of the alpine and alpine/forest ecotone that were covered afoot. Rock ptarmigan (~. mutus) were observed in Secs. 8 and 30, T27S, R59E, and a nest and a hen with 4 young were seen in the latter locality. Eagles Neither bald (Haliaeetus leucocephalus) nor golden (Aquila chrysaetos) eagles were seen within the West Creek valley. Several searches were made to locate an eagle nest reported (by Skip Elliott) to be a short distance south of the proposed dam site. It was not found. Bald eagles are common, of course, along the Taiya River and Inlet but nesting is uncommon as far inland as the area to be affected by the project. General Avifauna The kinds of birds to be expected within an area as large and diverse as West Creek are too numerous to verify as to their presence, abundance, or absence from a survey such as this. To cover the possibilities of species whose populations might or might not be influenced by the proposed project, Table 1 lists species that could be expected to migrate through, breed in, or reside entirely wifhin the area based on their occurrence in similar -14- I I-' V1 I , , ~p~t:--ar Vt\.LLLr r3ur,o", ,'" II..GlE:'RvUIQ.

The list also indicates species recorded in the Taiya valley in spring and summer of 1981 by Bruce Edmonton, U.S. National Park Service, those observed by us in West Creek, and those whose popula- tions might be significantly influenced, positively (+) or negatively (-) by the project. The latter notation is basically speculative and would require more study to be reliable.

In general, the valley walls are too steep and the valley bottom vegetation too dense for the valley to be an inviting recreational area. One resident, to our knowledge, commonly hikes into the upper valley. Except for his camp- site, the only sign of hikers, hunters, or campers encountered beyond the upper end of the clearcut or on the Lost Lake trail was of horse tracks, noted on 10 September, upstream from the dam site on the unimproved trail on the north side of West Creek. The identity and destination of the riders are unknown. Reports were obtained of 4 individuals who have hunted in the West Creek drainage. Upper reaches of the logging road were littered with shotgun shell casings and beverage cans used as targets. It was reported that some individuals formerly drove into the clearcut in hope of shooting black bears. The same area probably is hunted for blue grouse. The clearcut also was reported to be a favorite area for berry picking. Only one resident expressed concern over the potential of the project to adversely affect wilderness or aesthetic values. Difficulty of travel is the primary reason for low use of the area for hunting and wildlife observation. Additional roads or improved trails could be expected to increase such use materially. POTENTIAL IMPACTS ON WILDLIFE IN WEST CREEK DRAINAGE Mountain Goats Construction activities and their results (water storage and draw-down in the reservoir, water diversion, and hydroelectric generation) as pro- jected, would not, in themselves, have a direct influence of any measurable magnitude on mountain goat habitat or population. However, this area is of concern to Alaska Department of Fish and Game (personal communication with Dave Zimmerman, area game biologist) because they believe that their reduc- tion in goat hunting permits to the east may result in increased hunting pressure in the West Creek vicinity. Any project-related activities that influence hunter access to West Creek and surrounding goat habitat will be -19- of interest to ADF&G. The West Creek goat population can, however, sustain a larger harvest than it apparently has experienced in recent years. Moose and Deer Moose and deer do not occur in West Creek and are of inconsequential future concern. The valley itself would support too few moose to be of signifi- cance as a huntable population either with or without the planned project. While the reservoir, as planned, would usurp perhaps 1/4 of the present potential moose habitat, it would significantly increase the extent of desirable marsh and shallow-water habitat. Should deer become established in West Creek as a consequence of invasion over extended periods of years with mild winters, a population could not be expected to persist regardless of future developments. Black Bear Activities associated with construction of the dam, power tunnel, and powerhouse should be expected to influence the distribution of black bears on both sides of the creek from the dam site downstream. On the south side, activity might force bears to move southward to higher elevations, westward into the large glacial tributary stream, or up the West Creek valley. On the north side, bears might move northward out of the watershed or up the West Creek valley. These would be temporary movements followed by general readjustment of home ranges after construction was completed. The eventual reservoir would preempt about 400 acres of currently occupied bear habitat. The distribu- tion of fresh sign suggests that several bears occupy virtually all of the valley floor"and forested slopes and that they have, therefore, fully partitioned the habitat among the population. Individuals normally remain within a definable home range, but home ranges commonly overlap. It can be assumed that the distribution and overlap of these ranges are the result of mutual adjustments by the bear to share the available resources without excessively infringing upon each other. Loss of habitat to the reservoir would necessarily require a readjustment of home ranges and, if the remain- ing habitat were fully occupied, perhaps the eviction of one or more bears from the watershed. -20- Optimum black bear habitat within the West Creek watershed probably en- compasses about 10 mi2 . The maximum surface area of the proposed reservoir would be about 0.6-0.8 mi 2 • An area of less than 8 mi 2 studied by Lindzey and Meslow (1977) had a population of 23 black bears with widely overlapping home ranges. In West Creek, readjustment of home ranges would be a more likely outcome than loss of bears from the resident population. Brown Bear One or two brown bears reside partially and/or temporarily within the West Creek watershed. Its, or their, sign does not suggest that activities associated with project construction would be disruptive. If the bears are attracted to anadramous fish runs along the Taiya River, it is most likely that routes alternative to those affected by the project would be selected. Coyotes Coyotes are so ecologically ubiquitous and adaptable that they should not be influenced by the project. In any event, the area of the proposed reservoir seems to be little used by coyotes. Wolverine This species has been observed only in upper West Creek and the project should not be expected to affect them. Waterfowl Establishment of the storage reservoir in West Creek would result in the loss of about half (less than 3 acres) of the miniscule amount of open still-water habitat in the valley. In contrast, at a water surface level of 712 feet, the reservoir shore line would be approximately 5 miles in length. Based on an estimated average gradient of 1%, this would add some 60 acres of shoreline water less than 2 feet deep in addition to 300-400 acres of deeper water. Draw-down and refill rates and timing would influence habitat quality, but it is apparent that much more waterfowl habitat would be created than destroyed. -21- Grouse Of perhaps 8 mi2 of blue grouse habitat about 1/2 mi 2 of poorer qu~lity habitat would be inundated by the proposed reservoir. Assuming that the small number of birds there would move elsewhere and cause some readjustment among ranges in the peripheral population, any reduction in the overall population probably would not be measurable. Ptarmigan would not be affected by the project. Eagles Further effort should be applied to determining positively whether or not active bald eagle nests exist where they may be influenced by hydroelectric construction activities, installation, and operations. (See Mitigation Potential.) General Avifauna The character of potential influences is indicated in Table 1. Of those species that might be negatively influenced, none are rare or endangered. Only a small fraction of the populations that may be observed during migra- tions remains to breed in West Creek. Still, a certain amount of bottomland habitat would be irretrievably lost--perhaps 4/5 of the bottomland forest, 1/10 of the bottomland brush and woodland, and 1/4 of the marsh habitat. This loss could be expected to result in a reduction of the populations of some species, but not in the elimination of any. That influence would be balanced, however, by the addition or creation of habitat for other species, resulting in a more diverse avifauna overall. MITIGATION POTENTIAL This evaluation addresses the project alternative with a storage dam to meet Haines-p1us-Skagway energy requirements. Within that alternative there is little latitude for modifications that would significantly alter the effect on wildlife habitat. A lower dam (95 versus 107 feet; maximum water surface elevation 700 versus 712 feet) that would accommodate only Haines' require- -22- ments would reduce the reservoir area to a degree that would be inconsequen- tial in terms of wildlife influences. There does not appear to be a feasible alternative dam site. We do not believe, however, that the project as proposed would have measur- able detrimental effects on the populations of any species now present in West Creek. It would create new habitat for several species of waterfowl and other limnetic birds. Accordingly, the timing of drawdowns and pefil- lings of the reservoir may become of concern to Alaska Department of Fish and Game and U.S. Fish and Wildlife Service, depending upon species that became established. If the bald eagle nest reported near the dam site is verified as an active nest, the U.S. Fish and Wildlife Service must be notified and appropriate action be taken to assure compliance with legal requirements for its protection. In the vicinity of the proposed dam site, there is a narrow valley-bottom corridor that will be influenced by the access road on the north side of the stream, possibly affecting the travel routes of wide-ranging mammals. By keeping the final route of this road as close. to the stream as possible where the road leaves the clearcut and turns southerly toward the dam site, that effect can be minimized. In addition, attention should be given to keeping any ancillary structures out of that corridor area. Length, width, and depth of the proposed reservoir should be expected to have a negligible, if any, effect on the movement of wide-ranging mammals. -23- REFERENCES Lindzey and Nes1ow, 1977.

Specific objectives for the survey included: 1) Identify potential sites of cultural significance through research of ethnographic literature, review of pertinent registers and interviews with local residents. 2) Describe and map cultural resources identified during a reconnaissance of the study area. 3) Identify areas which merit special consideration during project design, construction and operation, and suggest mitigation measures. 4) Document areas of recent pertinent disturbance including roads and residence activities. BACKGROUND INFORMATION The Historical Setting There are two phases of cultural development in the Dyea/Skagway area which are the source for most of the cultural resources documented during this survey. These two development phases include the pre-contact use of the area by the Chilkat Tlingits and the post-contact development boom which accompanied the gold rush stampede in the late 1890's. -25- The northern end of Lynn Canal was included in the territory of the Chilkat Tlingits. The Chilkat name is used collectively to include Tlingits from the Klukwan and Chilkoot (Haines) territories. The Chilkat territory, including the drainages of the Chilkat, Klehini, Chilkoot, Taiya and Skagway Rivers, was rich in resources and included major strategic trade routes to interior Alaska (Goldschmidt and Haas, 1946:38). Prior to Tlingit occupancy of the area, Athapaskans from the interior had followed these routes to the coast and established settlements (Oberg, 1973:56). The trading economy was important to the power and resource base of the Chilkat. Trade items transported to the interior included eulachon oil,l/ cedar bark baskets, shell ornaments and other marine resources. Trade material coming to the coast included copper, hides, fur, thongs and sinew (Oberg, 1973:108). The Taiya Inlet area (Taiya and Skagway Rivers) seems to lack the abundance and diversity of resources and favorable weather of the more populated Chilkat River drainage. Nevertheless, small Chilkat villages or seasonal camps were established at Dyea (on the Taiya River) and Skagway (Goldschmidt and Haas, 1946), and the Taiya River trade route via Chilkoot Pass was actively used. The pre-contact ethnographic literature focuses on Dyea, leaving the extent of activity in Skagway somewhat in question. Dyea is !eported by some as a seasonal camp or village, although others indicate it had permanent status (Goldschmidt and Haas, 1946:50; Sealaska Corporation, 1975:578). Although Dyea may have had year-round residents, its role as a major Tlingit popula- tion center is in question. During the fur trading period the Chilkats retained control over interior trade routes. However, by the late 1800's a growing interest in gold strikes in interior Canada brought competition for the use of Chilkat routes and new forms of development to traditional Chilkat village and camp sites. l/Eulachon (Thaleichthys pacificus) is an oily smelt which spawns in many mainland rivers of the northwest coast. See also section on fishery evaluations. -26- A trading post was established at Dyea in 1884 to service the increasing number of prospectors traveling to the gold fields along the Fortymile River, and later to Circle City. Activity in Dyea and on the Chilkoot Trail gained momentum, and greatly increased following the news of the Klondike discovery in 1896 (Spude, 1980:23). Dyea quickly developed into a major staging area for large numbers of stam- peders. Buildings and tents sprang up in Dyea almost overnight and the shallow tide flats south of town became the site for unloading mountains of supplies. The original Chilkoot Trail headed north along the west side of Taiya River and the heavily used lower sections became a wagon road. Tents, cabins and shelters were erected along the trail for several miles out of town (Carley, 1981). Deep water docking facilities in Dyea were initially lacking and freight was loaded onto lighters which were grounded with the falling tide. Two wharves were eventually constructed in Dyea. The first, Dyea Klondike Transportation (DKT) Company wharf, was located southwest of town on the west side of Taiya Inlet and was connected to Dyea by a wagon road and toll bridge. The Dyea Wharf (or Long Wharf) extended directly into deep water, but was completed after the main gold rush activity had subsided and was little used (Spude, 1980). Activity in Dyea and on the Chilkoot Trail declined by the end of 1898. Many Dyea buildings fell into ruins, while others were moved to growing communities in southeast Alaska or were dismantled for lumber. Several homesteads in the area remained occupied and a small Tlingit population resided in the area into the 1930's (Spude, 1980). Geology Taiya Inlet occupies a secondary fault zone branch from the primary Lynn Canal-Chilkat Fault. The area is predominantly a plutonic intrusive for- mation, chiefly quartz diorite and granodiorite, which formed during the Jurrasic and Cretaceous periods (Yehle and Lemke, 1972). -27- Glacial activity throughout the area is evidenced by smooth, rounded bedrock outcrops and topographic features such as lateral and terminal moraines. Several large glaciers can be seen in the mountains surrounding the Inlet. Land rebound, characteristic of areas of glacial retreat, is an ongoing process in the area. At Skagway, a marine shell deposit now located at + 9.6 m above mean sea level was dated by the Carbon 14 technique at 2,880- 250 years old (Yehle and Lemke, 1972). Forest soils on slopes above the Taiya valley floor commonly have 15 to 30 cm of organic material over shallow, coarse-textured mineral soils which may be derived from colluvial material, from glacial deposits (as was the mouth of West Creek), or from weathering in place of the local granitic bedrock materials. Soils in the Taiya River valley bottom are built from alluvial materials which are predominantly silts, sands, and gravels. A characteristic profile is a thin ( 15 cm) surface of organic material overlying sand and silt of variable thickness intermixed with, or overlying, layers or lenses of coarse gravel materials. Many locations show soils disturbed by recent activities including land clearing, road building, or logging. These disturbed areas usually have very thin sur- face layers of organic material including moss ~nd litter, overturned stumps and debris (over roadways), and logging debris. Flora The general vegetation classification for the project area is coastal spruce-hemlock forest. The forests in the dam, reservoir and power corridor sites are dominated by Sitka spruce (Picea sitchensis) and Western hemlock (Tsuga heterophylla). Common shrubs in forest openings and edges include rusty menziesia (Menziesia ferruginea), blueberries (Vaccinium ~), and currants (Ribes ~). Forest openings with wetter soils contain devills club (Oplopanax horridus), red alder (Alnus rubra), Sitka alder (!. sinuata), willows (Salix ~), and other miscellaneous herbs and shrubs. In the flood plans and valley floors of the area the most common trees and shrubs are the black cottonwood (Populus trichocarpa), Sitka spruce, red and Sitka alder, willow, high-bush cranberry (Viburnum edule) and a variety of other herbs and shrubs. -28- Lodgepole pine (Pinus contorta) and western paper birch (Betula papyrifera) are common on the dry rocky ridges between the Taiya River valley and Skagway (Viereck and Little, 1972). A more detailed vegetational survey of the West Creek drainage is described in the Wildlife Survey report, also in this volume, and a vegetation map is presented (Figure 2). METHODOLOGY Assessment of archaeological and historical resources was conducted in the West Creek drainage on 20-28 August, 9-12 September, 29-30 October, and 6-7 November, 1981. This work included: (a) on-the-ground examination of much of the proposed development site to locate cultural resources and contem- porary activities in the project vicinity, (b) helicopter reconnaissance of some difficult access areas, and (c) surveys of ethnographic literature and registers and interviews with local residents (Appendix B-1) for additional knowledge of cultural resources. Surveys were conducted by Mr. Tim Moore, with technical assistance from Mssrs. Lyle Hubbard and Wally Olson, and field assistance from Mr. Nathan Bishop. Pre-field research was greatly assisted by information contributed by Mr. Robert Loescher of Sea1aska Corporation and the Klondike Gold Rush National Historic Park staff. Local informants contacted for cu1tura1- historical information included: Rick Burroughs -Long Bay area resident. Dave Clabaugh -Ranger, Klondike Gold Rush National Historic Park. Skip Elliott -Skagway city manager, Dyea area resident. Fred Hosford -Skagway resident. Alf Ka1vick -Dyea area resident. John and Lorna McDermott -Dyea area residents. Bob Rapuzzi -Skagway resident. Elizabeth Selmer -Skagway resident. -29- Areas of intended survey coverage were defined based on the layout of proposed hydroelectric developments (Figure 4) and the degree of cultural significance referenced by literature sources and local informants. Signi- ficant cultural resources were defined as identifiable artifacts or features which provide evidence of previous activity in the survey area. Areas of known high sensitivity and moderate or high archaeological potential were surveyed using transects to assure proper coverage. In the valley the transects were kept as wide as vegetation would allow while maintaining visual contact between two party members. On steep slopes, the transects were wider and voice contact was maintained. Survey areas were modified in-process due to inclement weather, inacces- sible topography, heavy vegetation, as well as to facilitate coordination of field efforts with those of other project teams. Generally, coverage was obtained of: 1) The proposed dam and reservoir site (about 500 acres), located approximately two miles upstream from the conflu- ence of West Creek and Taiya River, 2) The east and west ends of the power corridor, 3) The powerhouse site, 4) Most of the transmission line route, which follows the Skagway/Dyea road south along the east side of the Taiya River to Long Bay, and then southeast to Skagway, and 5) An alternate transmission line route along the west side of the Taiya River valley. An additional alternate transmission route which directly traverses the mountains to Haines was considered, but an on-the-ground survey was not conducted in this area. -30- Figure 4.

No testing or excavation was done during the course of the survey, as required in the field archaeolo~ permit. However, cut banks and disturbed areas were examined for evidence of artifacts dis- tributed beneath the surface. The areas observed provided a low yield of artifacts, and no conclusive pattern of artifact distribution at depth was noted. Items of cultural significance noted during the survey are generally described in the order in which they would be encountered moving from northwest (dam and reservoir site) to southeast (Skagway terminus of the transmission line) within the proposed development corridor. A numbering system for points of interest mentioned in the text is shown in Table 2, and is used on accompanying maps. ARCHAEOLOGICAL AND HISTORICAL RESOURCES Proposed Dam and Reservoir Site Rugged glacial topography and poorly aeveloped access routes made surveys in the dam and reservoir site (Figure 5) difficult. Access to the north side of West Creek was provided by a logging road which terminated in a clearcut landing approximately 1,000 m below the dam site. Access to the dam and reservoir was achieved by a trail which paralleled West Creek and by cross-country (unimproved access) travel. Blazes and minor trail im- provements appeared to be nearly the same age as the logging activity, and probably provide hunting access. The dam site and spillway area north of West Creek, and the location where test core drilling will take place, were surveyed. No evidence of historic trails or other cultural features were noted during visual reconnaissance of these areas. Cultural resources were not observed along the north side of West Creek or at the reservoir site. No mining activity was noted between the reservoir and the dam site. -34- Legend Project and survey area 1m..<. .2 rot, o TAI)A I~lEt -35- Figure 5. Proposed West Creek bydroelectric project development area. Access to the south side of West Creek was provided by helicopter. No resources of archaeological-historical significance were noted at the proposed dam and reservoir site. An aerial reconnaissance was made of the proposed dam and reservoir sites, and of the West Creek drainage below the development area. Conversations with local residents provided two additional possibilities for areas of cultural significance in the dam/reservoir area. Mr. Bob Rapuzzi, a resident of Skagway, suggested a trail may have existed along the south shore of West Creek and traversed the mountains to the Chilkat River area (Klukwan). Although it is possible to traverse the route, the rugged topography makes it an unlikely route for frequent travel. No evidence of the trail was noted during a cross-country survey conducted along the proposed route. However, vegetation could easily have oblit- erated the historic trail. Mr. Skip Elliott, a resident of Dyea, has collected information on the historical activities of the greater Dyea area and has hiked extensively in the West Creek drainage. Historical records Mr. Elliott obtained from Skagway City Hall indicated the presence of mining claims in upper West Creek valley. Mr. Elliott felt that most, if not all, of the claims were outside the area to be developed. He has made several trips into the upper valley looking for the claims, without success. It is not known if any of the claims were actually worked. With the vegetation cover in the area, small claims with limited activity would be very difficult to locate. During the reconnaisance of the reservoir area, this survey crew found no indication of mining activity. Power Corridor Due to the lack of proposed surface disturbance along most of the power corridor route and difficult access through dense forest cover, only the corridor ends (west end at the dam site and east end at the powerhouse) were surveyed. The approximate area of the proposed access road for the power shaft above the power house was also examined. The western end of the corridor, located immediately upvalley from the dam, was surveyed concurrent with the dam/reservoir survey. No cultural material was observed in this area. -36- The eastern end of the corridor was surveyed concurrent with the power- house site survey. This end of the corridor, including the power shaft and access road(s), is in steep terrain covered with glacial moraine material. At the time of the survey the proposed location for the access road was not known. Therefore, a general reconnaissance was conducted on the hillside south of the powerhouse site and at the power shaft location. The only evidence of activity noted in the area was a steep unimproved trail to Lost Lake (Figure 6) and recent survey stakes and flagging along the National Historical Park boundary. No mention of the Lost Lake trail was found during research, so it is not known how long the route has been used. No other cultural material was noted in the area. Powerhouse Site The powerhouse site now proposed is located west of the valley floor, on land which is administered by the National Park Service (#2). An alter- nate site is located near the West Creek canyon in an area with large morrain deposits and bedrock outcrops. The valley floor at the mouth of the canyon is private property. Several contemporary houses, numerous out-buildings, garden plots, and assorted refuse were noted on either side of West Creek in the vicinity of the alternate powerhouse site. Most, if not all, of the material scattered around these residences appears to be within private property boundaries (Figure 7A). The tail race from the prop~sed powerhouse will go through this area near the base of the hill. The proposed powerhouse site is situated 300 m south of West Creek at the base of the hill (Figure 8). The valley floor in this area is coarse aleuvial material mixed with some fines. Humus and moss covers the area at a depth averaging 20 cm or less. Unimproved roads meander through the area along the base of the hill and east to the main road (Figures 8 & 9). The roads appear to have been made by light grading or repeated driving. Road widths vary from 8 m for a single track to 35 m at junctions and in areas of logging activity. -37- Figure 6. Survey area.

Taiya River Valley Legend See 7A SCALi. / I / / The powerhouse location contains two small sheds with a large assortment of contemporary debris; an approximate age of 30 years was confirmed by Fred Hosford. The debris around the sheds includes appliances, stoves, bed spring, building material, piling, steel pipe, and a two-hole out- house. A long cleared strip goes up the hill from the sheds about 150 m. A large tree at the uphill terminus and a wire on the ground indicate it was a long wire antenna route. Figure 8. Looking south at powerhouse site. Figure 9. Southeast from powerhouse area showing transmission line corridor. -42- The south side of West Creek upstream from the canyon mouth was surveyed with several transects parallel to the creek where topography permitted. The area was checked for indications of trails. Small game trails were noted. No cultural material was observed. The north side of West Creek was surveyed in a similar manner. Just west of the log bridge which crosses West Creek, a road forks to the south into an area known as Wagon Wheel Ranch (#3). There is a small well-maintained log house, a log out-building,a large log home under construction, numerous plots of flowers, and several large garden plots. In the flats toward the canyon mouth there is an accumulation of aluminum irrigation pipe which had apparently been part of a gravity flow system for garden water. There is evidence of wood cutting activities in the area. No items of archaeological or historical significance were noted at the proposed powerhouse site. Transmission Line Corridor The proposed 9 km long transmission line corridor extends from the power- house site southeast across the Taiya valley, along the east side of the Taiya River into Long Bay, and then south to Skagway. The following de- scription of the survey route is generally presented in a north to south progression. However, the Chilkoot Trail survey is described from the point where the trail crosses the Skagway-Dyea road northward to the Kinney Bridge area (which is outside the transmission corridor to the north.) Powerhouse Site To Taiya River This section of the transmission line corridor (Figure 5) lies within the Taiya valley and is included within the boundaries of the Klondike Gold Rush National Historic Park. However, the corridor may cross private inholdings within park boundaries. Numerous cultural artifacts, which were generally related to the gold rush era, were documented along this section of the line. Briefly, these included the Chilkoot Trail route, debris and structures along the trail -43- and the remnants of the northern portion of the community of Dyea. The presence of the native village of Dyea was not identified by this survey team and its existence and former location is known only through literature research. Evidence of the pre-gold rush native village was probably overlain by, and incorporated into, site developments which followed. The short section of transmission corridor between the powerhouse and the Skagway-Dyea road contains numerous contemporary cultural resources. The area is criss-crossed with roads and tracks which lead to house sites, small abandoned sheds, barb wire fencing, and a new concrete house founda- tion (#4). Associated material noted in this area included abandoned wood stoves, large kitchen appliances, 55-gallon drums, batteries, motor vehicle parts, building supplies, and food and beverage containers. This area has been selectively tractor logged as evidenced by tracks, stumps, and irregular piles of dirt, rock, and wood. Because of the rapid growth of vegetation it is difficult to determine the full extent of the area logged. However, scattered evidence of logging (primarily west of the main road) extends south to near the Dyea junction (#8). The transmission line corridor continues east to an intersection with the main road and then follows it south (Figure 10, 11, and 7B). In the section between the house foundation (#4) and the main road the soil changes from the shallow rocky aleuvium in the west to a deeper deposit of silt and sand. At the Kalvick residence (#5) the well point hit gravel at 5 m. Gardens and other disturbed lands here and to the west are primarily soil with very little surface gravel. The Kalvick's have built a house, several out-buildings, and a fenced yard and garden plot. The main road which runs from Skagway to West Creek was constructed during the late 1940's. The road corridor was opened by pushing the vegetation cover and top soil to either side. The all-weather road bed consists of river gravel that was hauled in. The road bed averages 8 m in width with -44- a graded apron on either side. The width of the aprons along the roadside varies greatly from 4 m to over 20 m. There is some disturbance beyond the apron where the excess construction material was deposited. Figure 10. Junction of transmission line corridor at main road. Figure 11. Looking north toward the house shown in Figure 10. -45- The first historical material found near the transmission line corridor was at the Mathews Cabin (#6, Figure 7C). The walls of the cabin are intact but the roof has fallen in. According to Spude (1980), this was the residence of Mr. William Mathews, a Tlingit and long-time resident who homesteaded here in the 1920's (Figure 12). At this point the total width of the road's right-of-way is quite narrow when compared with other sections along the road. Some scattered artifacts and pits were noted around and behind the cabin. The area of activity extends 40 m to the northwest to the edge of a slough and southward along the slough to the Dyea Road (#7). It is diffi- cult to determine origins of the material but most (particularly away from the cabin) is probably from the gold rush era. Material noted included enamel pots and pans, rusty cans, sheet metal and scraps of iron. Figure 12. Mathews' Cabin. -46- The triangle formed by the three roads has been disturbed by road building, but does contain partial remains of a heavy wagon (wheel, axle, and heavy metal straps) and assorted material typical of that scattered along the trail (#8, Figure 13). Figure 13. West Creek road looking northwest. Dyea lies to left. South of the road gold rush era structures, pits, and artifacts occur more frequently (#9). This area has been well documented in a previous investi- gation by Carley (1981), and numbers indicated on Figure 7C are deSignations assigned by Carley. The structure showo.in Figure 14 is about IS m south of the road. -47- Figure 14. Gold rush era building SIO. The main road corridor between the Dyea junction and Taiya River Bridge (#10) is generally wide (up to 45 m), but narrows to 15 m near the Chi1koot Trail crossing (1111) and the bridge (Figure 15). The soil in the area is predominantly silt, but with lenses of gravel. Figure 15. West Creek road from Taiya River Bridge towards Dyea Junction. The Chilkoot trail runs south-north between the modern road and the Taiya River (Figure 16). The trail crosses the Skagway-Dyea road 175 m northwest of the Taiya River Bridge and continues north for 700 m before ending at the edge of a large slough (#17). It should be noted that the historic trail at this point was actually a wagon road which continued north of the slough approximately 500 m before crossing the Taiya River on the Kinney Bridge. Spude (1981) noted that the trail route can be easily distinguished up to the Kinney Bridge by remains of building foundations and tin cans. Following the Chi1koot Trail north from the road junction the first feature noted is a contemporary earthen ramp partly spanning a slough (#12). It appears that the material for the ramp came from a disturbed area across the trail. -48- Figure 16. Chilkoot Trail. Legend • House -Road ---Trail --- Stream ):( Bridge ..

The trees were used as "fence posts" and their size indicates this site is from the gold rush era. Tree alignments in the downtown Dyea area were used for comparison. A small contemporary fallow garden plot is located to the west. Figure 17. Tree alignment at #13. Th~re are three rectangular pits further to the north (#14), adjacent to a clearing that contains remnants of wooden structures and recently culti- vated garden plots (#15, Figure 18). The site appears to be from the gold rush era, but it has been disturbed and altered by recent activities. Recent artifacts were scattered about; however, some pieces of tin, stove pipe, galvanized roofing, and metal rods are in a similar state of decay as the gold rush material observed in the Dyea area. Figure 18. Building remains at illS. The next major feature up the trail is the log cabin at McDermott's farm (#16) which dates from 1897-98 and is still occupied. The cabin shows common log construction problems, including lack of foundation, sagging 2 and deterioration of some logs (Figure 19). A 175 m area around the cabin has been recently cleared and fenced (Figure 20) to accommodate several large garden areas and farm animals. The trail reaches the slough 150 m north of the cabin. A large pile of soil and trees has been pushed to the north edge of the property near where the trail disappears at the edge of the slough. The soil is predominantly fine river deposits, silt, and sand. -51- Figure 19. 1898 Cabin, McDermott's. Figure 20. Looking southeast across cleared land at McDermott's. Tin and light metal artifacts are scattered along the trail the entire d~s­ tance from the Skagway-Dyea road to the slough. The composting vegetation tends to mask the smaller materials such as heavier metal pieces, glass and ceramic fragments, nails, and other construction materials. No attempt was made to catalog all the artifacts scattered along either side of the trail, nor was any digging done. This section of the trail was surveyed using transects of 10 m spacing parallel to the trail. Dense vegetation pre- vented complete coverage in several areas. The survey area was extended south of the Skagway-Dyea road and out of the defined transmission corridor in order to attempt to identify the native village site of Dyea and to estimate its proximity to the proposed hydro- electric development. A survey conducted for Sealaska Corporation (1975), by Whilsey and Ham, Inc., Seattle, had designated a Point of Beginning (POB) or main datum for native village site no. 1303 based on information obtained from two informants, though no artifacts were located. The datum is on the northern boundary of the site and is located 700 m south of the Taiya River bridge. Carley (1981) located two additional structures (designated as "Indian Houses" on the 1918 Pullen Homestead map) which are 425 m north of site 1303 datum. The remains of these structures appear to be more recent than the gold rush era. It is not known if the structures were located on sites which pre-date contact with white men or if the natives had moved northwards because of increased gold rush activities. Available infor- mation indicates that, while the exact location of the native village site is not known, it probably lies south of the proposed transmission line corridor. Taiya River to Long Bay (Nahku Bay) This section of the transmission line corridor traverses the east side of the Taiya River flood plain and crosses a steep rocky ridge of exposed bedrock into Long Bay. -52- The trailhead for the Chilkoot Trail currently used by hikers is located at the southeast end of the Taiya River Bridge (#18, Figure 21). The new trailhead was placed on the south side of the bridge because there is no longer any bridges across the Taiya River on the original trail. Figure 21. Taiya River Bridge. Chilkoot Trail trailhead on right. The main road south of the bridge was constructed by the same manner described in the previous section (Figures 22 & 23). -53- Figure 22. View south from Taiya River Bridge. Figure 23. View north toward Bridge from 8.3 mile. The survey was conducted by walking transects south from the Taiya River Bridge. Both sides ~f the Skagway-Dyea road have been scarred and inundated by flood waters from the river. Sloughs and swamps on either side of the road dictated some modification of transect routes. A group of wooden structures was noted in a clearing 50 m east of the main road at mile 8.4. The two houses and several out-buildings, now in various stages of disrepair (#19), were constructed in the late 1940's. The southern-most house appears to be occupied at least periodically, but no residents were seen during the survey (Figure 24). The northernmost building, which is deteriorating, appears to have been constructed from pre-fabricated material. Bolts with large washers were used to fasten panels together. The main construction materials are 2 X 4" lumber and composition board. -54- Figure 24. "Army" building. Discarded debris in the vicinity included a pile of well used lead-acid batteries, various sizes and type of electrical wire (some had the insula- tion burnt off as part of a salvage operation), mesh wire, pieces of furniture, miscellaneous automotive parts, pieces of a fishing net with floats, a Chevrolet pick-up truck and miscellaneous food and beverage con- tainers. A small freshwater spring was noted at the base of the ridge 25 m east of the houses. A National Park Service ranger station, campground and trail-head parking are located on the west side of the Skagway-Dyea road at mile 8.3 (#20). The ranger station consists of three temporary plywood buildings, a gravel parking lot and a road winding through the willows to a location where tables, toilets and fire areas are provided. The entire area is located on the Taiya River flood plain. -55- A small marine ·shell deposit was discovered 50 m south of the 8.0 mile post on a small rock bench 3 m above the road (#21, Figures 25 and 26). A careful visual examination of the exposed po-rtion of the deposit failed -to identify any indication of cultural material. However, no digging was done at the site so only a small portion of the deposit could be seen. The deposit is more completely described in Appendix B-2. -56- ." ,,- Figure 25. Marine shel-l deposit. 1" ~ ~, Figure 26. Marine -"'.; shell deposit. A small occupied house, outbuilding and animal corral are located 75 m east of the 8.0 mile post (#22). South of the 8.0 mile post the road traverses the edge of Taiya Inlet on a bench blasted out of the hillside. Two widely spaced north-south transects were surveyed in a basin area approximately 300 m above the road. The main reason for covering the area was to investigate a mine (prospect) shown on the topographic map (Skagway B-1 Quadrangle, T27S, R59E, Sec. 35). The prospect was not located, but it is most likely outside of the proposed development corridor. An occupied trailer is located just east of the Skagway-Dyea road at 7.2 mile (#23). At mile 6.6, a single steel wire telegraph/telephone line was discovered (Figure 14). The line is broken and ends 25 m uphill (east) from the roadway. The line angles towards the ridge top on a bearing of S38 0 E (UTM N6593300M/E480450, T27S, R59E, Sec. 34). At the top of the ridge (UTM o N6593250M/E480650M, Sec. 34) the line's bearing changes to S45 E for approximately 100 m down into the Long Bay drainage where its route was lost (Appendix B-3). This line may have connected Skagway and Chilkoot Pass with Dyea, as described in an 1898 newspaper item in the Dyea Trail entitled, "Sunset Telephone Company--communications with Skagway and all points on the Dyea Trail" (Spude, 1980:37). An attempt was made to find additional intact sections of line, but road building and other activities along the route has damaged the line. Three short pieces (less than 10 m) of wire and one white ceramic insulator were found just above the road between 8.0 and 6.6 mile. Three short isolated pieces were found in the 5.5 mile area west of Long Bay and a short piece of similar wire was found north of Dyea running parallel to the Chilkoot Trail. No additional sections of intact line were found. A NPS ranger familiar with the upper sections of theChilkoot Trail indicated that long lengths of wire are still visible; however, the insulators are gone, at least on the sections of line on or near the trail. -57- Figure 27. Green glass insulator on line from Long Bay to Skagway. Two small occupied cabins or sheds overlooking the Taiya Inlet at 6.3 mile are visible from the road. Access is by a short driveway to the west of the road (/125). Three houses were observed at the head of Long Bay at 5.1 mile (#26). A log cabin and conventional house are located to the north of and within 10 m of the road. Rick Burroughs, who lives at the cabin, thought it was built in the 1940's. An unoccupied "A" frame house is 75 m to the north of the road and about 50 m northwest of the large house. There are numerous out-buildings (woodsheds, old root celler, garage, power plant, and storage sheds) associated with this group of houses. The area between the road and the beach is densely covered with vegetation. There is a small pit 20 m south of the log cabin. It contained a small amount of recent trash, mostly food and beverage containers. No other features were associated with it and its age probably corresponds with that of the log cabin. This strip of land also has a recently constructed mesh wire pen for small animals (goats) and a small fenced garden plot. -58- There is an occupied house on the beach at Long Bay below the road at 5.3 mile. Access is by trail from the road (#27). Long Bay to Skagway The section of the transmission line corridor between Long Bay and Skagway traverses a steep rocky ridge on the north end before the ridge flattens out near its southern terminus at the Skagway River. Surveys were not conducted in the northernmost area as steep topography made the presence of cultural resources unlikely and foot travel was dangerous. Transects paralleling the Skagway-Dyea road were used to survey the corridor from 4.5 mile south to the Skagway River. The surveyed area contained only contemporary cultural resources. Informa- tion gained from literature and local informants indicates there was very little, if any, gold rush activity in this area. The Skyline Trail begins just north of the Skagway-Dyea road (#28, Figure 28). This ridge trail provides hiker access to the alpine region of AB mountain. The trail forms the eastern boundary for a four-acre parcel of patented property belonging to Elizabeth Selmer of Skagway. The property lies west of the trail and includes an outhouse and remains of a burnt cabin 50 m northwest of the trail head. All of the material in this area is recent. A small shed at the Skyline Trail head (20 m northeast of road, Figure 29) was placed there by a person trying to patent that area (#28). An addi- tional occupied cabin was noted 200 m north of the Skyline Trail (#29). Background information on the status and activity of the Skyline Trail area was provided by Elizabeth Selmer. Southwest of the Skyline Trail (Figure 28), a road provides access to a rifle range, a small cove north of Yakutania Point (road is blocked to vehicular traffic) and to the Skagway River northeast of Yakutania Point. A well-traveled trail leads from the rifle range to the remains of a sus- pension foot bridge (#30) on the Skagway River. The trail passes two large pieces of cable (4.5 cm diameter) which are anchored in a rock face. -59- Figure 28.

Remnants of a wooden boardwalk were noted. Wooden timbers bolted together to form a bridge frame were visible on a small willow covered island in the Skagway River (Figure 28). The bridge was for foot traffic only and was removed when the main highway bridge was constructed upstream from Skagway. 2 A small pet cemetary (10 m) (#31) with 13 graves is located 15 m above the bridge-cables. MOst of the graves are enclosed by a water pipe frame that stands 20 em off the ground and is painted silver. Most graves had metal name markers, one was wood, one wood cross, one marble marker (was broken and unreadable) and two were unmarked. Two grave markers provided the dates of 1958 and 1980. The 1958 marker has a round brass Skagway dog tag tacked on the marker. Alternate Transmission Line Corridors Two alternate transmission line corridors are under consideration by R.W. Beck and Associates, Inc.; one from the powerhouse along the west side of the Taiya River valley and the second from the powerhouse site over the mountains to the west, directly into Haines. -61- The alternate corridor along the west side of the Taiya valley did not receive as complete a survey as the primary route on the east side of the Taiya River. However, the area from the powerhouse site to the tide flats was surveyed by foot-travel along roads and trails. Moving south from the powerhouse, the first mile of corridor contained several occupied and abandoned residences. Most of the material appears to be recent (1940-50's), however, it is possible that some of the buildings may be older. From the southern end of Section 22 to a point several miles south of the Dyea townsite there is evidence of gold rush activity, particularly in the area adjacent to and south of the townsite. Remnants of the DKT dock, the toll bridge and wagon are still visible, according to Spude (1980:177). The survey team did not cover any of the DKT area. There are also several residences and garden plots in this section of the corridor. Four resi- dences were noted in the valley and one was reported on the hillside. Due to the area's close proximity to Dyea, it is quite possible that some, if not all, of these dwellings date from the 1898 period. The entire lower mountain slope through this area was logged heavily in the early part of the century. The second alternate route (traversing the mountains to Haines) was not surveyed due to the difficulty of access in rugged terrain. The area has a very low potential for cultural resources. POTENTIAL FOR IMPACT AND MITIGATION RECOMMENDATIONS This evaluation addresses the potential fo~ project impacts and mitigation for the defined survey areas. Future rerouting of hydroelectric project development into areas outside of the surveyed corridor would require additional surveys prior to ground disturbance. -62- West Creek Drainage The survey did not reveal any cultural resources within the dam site or reservoir. The possibility of mining claims along the periphery of the reservoir area does not warrant any further investigation at this time. However, during any vegetation clearing activities which accompany con- struction, surpervisory personnel should be on the alert for signs of small mining operations. If cultural remains are located, further surveys should be made to determine their extent. The remainder of the dam site and reservoir area should not require further investigation or mitigation efforts. No resources of cultural significance were identified within the areas of the power corridor which were surveyed. These areas included the west end near the dam site, the east end near the powerhouse site, and the approxi- mate location of the powershaft access road. For non-surveyed areas along the power corridor, it is recommended that an archaeologist should investi- gate if there are future plans for ground disturbance in this area. Crews should notify a designated person whenever cultural materials are discovered that were not noted on the original survey. Taiya River Valley No significant cultural resources were observed at the power house site near the confluence of West Creek and the Taiya River. However, additional archaeological investigation is recommended if the site is relocated during subsequent planning and/or if surface disturbance activities occur outside the surveyed area during construction of access roads, staging areas, and other ground disturbing activities. The primary transmission line corridor across the Taiya valley will cross the Chilkoot Trail and areas of gold rush activity. Placement and design of the transmission line in this sensitive area, and as it transects the valley, will require consultation with and approval from state and federal regulatory agencies. Additional information will be required before final impact assessment and mitigation measures can be completed. Necessary design information would include, at least, the exact route to be traversed, -63- type of line (buried, elevated, or a combination) and projected maintenance and right-of-way requirements for each line section. Additional archaeolo- gical investigation is recommended for the exact location at which the line will bisect the Chilkoot Trail. Aligning the transmission line along the existing Skagway-Dyea road would result in the least cultural impact. In many cases the disturbance caused by road construction appears to have been extensive. However, the use of all or part of the road corridor would not eliminate additional planning of mitigation measures prior to route approval. An elevated transmission line would minimize the impact on cultural remains in sensitive areas. However, the visual impact of the elevated line must also be considered. Sections of the corridor in the Taiya valley will cross private parcels of land, some of which have had considerable land alteration. It is possible that cultural resources may have already been disturbed in these areas. Parts of the private property, especially around areas of disturbance, were not surveyed. Four additional areas within the eastern Taiya River valley which warrant consideration include (a) the modern Chilkoot Trail and Trailhead, (2) the group of structures east of the Skagway-Dyea road at mile 8.4, (3) the NPS ranger station at "S.3 mile, and (4) the marine shell deposit at mile S.O. The avoidance of these areas during routing will eliminate the need for further investigation and mitigation. It is recommended that a more inten- sive investigation be conducted at the mile 8.4 houses and the 8.0 shell deposit should it be necessary to route in the immediate vicinity of these features. East Ridge to Skagway In the Taiya River to Long Bay section of the development corridor, the only significant cultural resource located was the" steel wire line over the ridge. Impact on this site can be eliminated by avoidance of the area. If this is not feasible, the line should be marked and activity in the imme- diate area designed to avoid the trees supporting the line. -64- In the Long Bay to Skagway section there are two areas of sensitivity which should be avoided to eliminate disturbance. These include the shed and trail head area for the Skyline trail and the pet cemetary and suspension bridge remains near the Skagway River. While neither might be classified as significant resources, their avoidance would eliminate possible problems. Alternate Corridors It is recommended that the alternate route along the west side of Taiya River valley receive a more thorough archaeological-historical survey if this is selected as the preferred route. The close proximity of this route to historic Dyea, passage through NPS administered lands, and high visi- bility suggest this route may be more sensitive and difficult to mitigate than the east Taiya valley route emphasized in this survey. The high mountain corridor to Haines would also require an intensive survey and mitigation program if it was selected as a preferred transmission route. Higher elevation areas may be sufficiently surveyed by helicopter, with on-ground survey limited to less difficult access areas where there is greater potential for cultural remains. -65- REFERENCES Carley, C.D., 1981.

Scope of Report This report presents results which address the objectives outlined above. The limited nature of fishery impacts resulting from the West Creek hydro- electric project is discussed herein, and measures to protect, mitigate or enhance fishery values are examined. -67- METHODOLOGY A reconnaissance by Mssrs. Dan Bishop and Alex Milner was made on 16 and 17 July, 1981. From this investigation, four small tributary streams entering West Creek above the lowest gorge were identified and designated (Figure 30) for minnow trapping. This work was designed to determine if anadromous or landlocked fish specie(s) were present above the lower gorge. Two-foot, galvanized wire minnow traps baited with boraxed salmon eggs were fished for two hour periods in three tributaries, while the fourth tributary (across West Creek and immediately above the dam site) was fished for only 40 minutes because of helicopter scheduling. Ten traps were deployed by S. Elliot (ADF&G), M. Schwann (ADF&G), and Joe Wallmo~ party to this investigation, in each of the two tributary channels of the middle basin (within the clearcut) on 27 August. Twelve traps were used . in the tributary entering West Creek one mile above the dam site and eight traps were used in the small stream entering from the south immediately upstream of the dam site on 11 September by D. Bishop and J. Wallmo. Periodic examinations were made of the clearwater tributary entering West Creek immediately downstream of the West Creek Bridge. Counts were made of Dolly Varden seen in a pool of this tributary. During the entire survey period the flows of both the Taiya River and West Creek were high and waters were turbid, restricting visibility from the stream banks. Individuals contacted as part of the fishery investigation included: Dave Cantillion -Regional Biologist, Commercial Fisheries Division, ADF&G. Discussed potentials and problems of a hatchery on West Creek. -68- Figure 30. ~e'L~YOir r:trIM~-tct­ e.fe\,/' 712 I ------- Location of tributaries examined for fishery habitats. o Profc~e d ])3 ...... 4:h ~ CONIOUR ~ CAL E 112 IN1ERVAL 100 h.

RESULTS OF FISHERIES INVESTIGATION West Creek and Tributaries Above Upper Gorge Reports by residents of Skagway and Dyea indicated that few if any fish resided or spawned in upper gorge waters near the proposed dam site. No fish were observed during examinations of these waters by members of this study team or by D. T. Hoopes during his reconnaissance on 25 August, 1981. No fish were captured during minnow trapping in two tributaries entering this portion of the West Creek drainage (see Figure 30). Both of these tributaries had sections and stream edges with ample area of gentle stream velocities and with fine gravel bed material suitable for spawning. No attempts were made to trap fish in the fast turbid waters of West Creek above the dam site. If fish reside in this upper basin, they are most likely to be found in clearwater tributaries. -70- The gorge below the proposed dam site contains a series of cataracts and chutes with sustained high velocity conditions (see Figures 31, 32 and 33). Upstream migration of salmonids is likely to be greatly limited or prevented, at least for the period of high flows from May to November. West Creek and Tributaries in Middle Basin Several local people reported fish in two small mountain drainages entering West Creek as it passes through the up-river portion of the clearcut. Trapping on 27 August by S. Elliott, M. Schwann11 and J. Wallmo supported these reports as did observations by D. Bishop and D. T. Hoopes. Dolly Varden were present at very low density levels (some of the lowest in Southeast Alaska) and representative samples of fish were aged at 3 years. Elliott believes this population is probably resident (land-locked). These two small streams join into a lower section with gentler gradient before entering West Creek. There is ample good quality spawning gravel in the lowest portion of these tributaries. Iron staining in the gravels indicate that this lower part of the tributary receives flow from upwelling groundwaters. West Creek flows at high velocity without relief in this middle basin be-. tween the upper and lower gorges. The streambed is dominated by boulders and cobbles. There is little, if any, rearing or spawning habitat in this channel. Lower Gorge of West Creek This extended section of rapids and falls is bordered and confined by steep slopes or rock walls. The flow, as seen from the adjacent northerly slopes, provides absolutely no access for fish traveling up the stream bottom. No slow flowing water areas were seen (see Figure 3~. Blockage to fish migration upstream may be more a function of sustained high velocities than a result of a particular falls or rapids. lIS. Elliott and M. Schwann are ADF&G fisheries biologists with the Sportfish Division, Juneau. -71- Figure 31. Rapids below damsite. Figures 32 and 33. Cataract areas below damsite. Drop in lowest cataract shown in Figure 34 is 1.2 to 1.8 m. -72- West Creek Between Lower Gorge and Taiya River Confluence The single tributary joining West Creek in this section enters the main stream immediately below the West Creek Bridge. This tributary is fed by a mountain stream, by local areas of upwelling spring flow, and by flood- waters during high flows of the Taiya River (Figure 35). There is no evidence that any significant fraction of this tributary's flow derives from surface or groundwaters of West Creek. This tributary supports anadramous Dolly Varden. Adult fish were ob- served congregating in a pond on the stream which is probably spring fed. Two counts were made of fish in the pond: 60 and 48 Dolly Varden were counted, respectively. This tributary stream may also support a few fall chum (Oncorhynchus keta) , and coho (~kisutch) salmon, although local residents have not seen them in this stream,. and none were seen during this investigation. Shorelines of Lower West Creek and Taiya River Turbidity of water generally prevented any meaningful observations along the shorelines of lower West Creek and the Taiya River within one-half mile downstream of the confluence. However, when the stream was visited on 30 October, 1981, water clarity had begun to improve. An examination of the shoreline near the mouth of West Creek showed no spawning salmon, though a chum salmon carcass from up the Taiya River was caught in log debris on the river below the West Creek confluence. West Creek, near its con- fluence with the Taiya River, was neither minnow trapped nor seined for possible resident population. West Creek below the lower gorge is shown on Map 1, and prominent streambed and streamside conditions are indicated. Eulachon Spawning Habitat in Lower West Creek Vicinity The Eulachon runs of the lower Taiya River also extend into the West Creek confluence during some springs. The possible impact of regulation and alteration of West Creek's stream flows upon Eulachon spawning is very -73- -74- Figure 34. Series of falls and rapids in West Creek lower gorge directly upstream from Taiya River valley. Figure 35. Tributary whioh enters West Creek below bridge. Dolly Varden found in pools. difficult to assess. It is conceivable that timing or location of Eulachon spawning may be altered during some springs by the influence of changed temperature and volumes of West Creek waters. This possibility cannot be evaluated at this time, due to both the minimal information available on West Creek's Eulachon run, and the present lack of stream temperature information. A summary of Eulachon life history is provided so that some insight might be developed concerning the possible role of Taiya River flow conditions in influencing Eulachon spawning runs. Eulachon (Thaleichthys pacificus) are Pacific smelt which spend two to three years in marine environments, then migrate to rivers and streams of the Pacific Coast from northern California to northern southeast Alaska. These silvery fish range in length from 125 to 200 mm at 2-3 years of age. They are exceedingly rich in oil and have been traditionally rendered for cooking oil-by coastal and near-coastal Native peoples of the Northwest and Alaska. Spawning of Eulachon in Lynn Canal-Taiya Inlet streams occurs in early May, and is evidently of shorter duration than in more southerly streams (i.e. southern British Columbia). Great numbers of fish, probably domi- nated by two-year olds, enter the sandy mouths of rivers to spawn. Fertilized eggs eVidently settle upon the sandy bottom and become indi- vidually attached to sand grains through an external membrane. Newly hatched larvae are weak swimmers and probably migrate with currents back into the estuary. Eulachon streams in southeast Alaska are exclusively mainland rivers, with significant contributions by glacial meltwaters and high sediment loads. The early May spawning period to which Taiya River Eulachon are adapted would provide conditions with increasing volumes of meltwaters and suspended sediment load, and with water temperatures which are likely to fluctuate diurnally, but remain at relatively low levels. As yet, no information has been found which discusses or identifies the ecological requirements of spawning Eulachon. -75- POTENTIAL IMPACTS ON FISHERIES The construction of a dam and a reservoir in upper West Creek will destroy no fishery values in that part of the watershed as none have been found to exist. The proposed impoundment will inundate the lower portions of both upper drainage tributaries which were fished with minnow traps during this study. It is possible that some potential spawning and rearing habitat may remain in one or both of these clearwater tributaries above the limit of reservoir water, athough this has not been verified with accurate engineering data determining the reservoir limits. Such potential habitat would be useful if stocking the reservoir with fish was attempted. The reservoir waters are likely to be considerably less turbid than present stream waters, with only colloidal sized particles remaining in suspension near the lower end of the impoundment. Stream velocities will, of course, be radically reduced in the reservoir area. The portion of West Creek between the dam and the powerhouse may be subject to highly variable flow conditions ranging from very low flows (likely in winter), to sizeable or large releases at other times of the year. No fish are known to reside in or migrate through the mainstream of West Creek above the lower gorge. However the two small tributaries of the middle drainage which contain fish in their lower section may be affected. Impact could result from partial loss of tributary channel flows to groundwater because valley sediments are no longer saturated. Occasional resident Dolly Varden from the two above mentioned tributaries probably drift into the mainstream and are swept out of West Creek by high flows. Greatly reduced flows will allow fish caught in the mainstream to find pools and eddys in which to reside, at least temporarily. The lower gorge of West Creek presently contains no fish habitat. Develop- ment of a hydroelectric facility could result in pools in portions of the gorge. These pools may be attractive to fishermen, seeking Dolly Varden which may colonize these waters. -76- West Creek below the lower gorge and the proposed power house site contains no identified salmonid habitat, although the stream does provide an access route of several hundred yards by which anadromous Dolly Varden and pos- sibly a few chum salmon reach the mouth of the tributary stream (see Figure 37). There is no reason why this migration route need be disturbed as a result of powerhouse installation and routing of tail race water back into the stream channel. Stadia traverse information on the lower stream section has been provided to assist with evaluation and facility design. The possible impact of West Creek flow regulation upon Eulachon spawning in the Taiya River has not been analyzed. A meaningful body of informa- tion is simply not available. Most importantly, the spawning preferences or requirements of Eulachon have not been determined, and no agency or group interest in such work fundamental to habitat protection or management has not been identified. PROTECTION, MITIGATION AND ENHANCEMENT The limited number of Dolly Varden present in the middle basin of West Creek are probably resident and stunted in growth. No protective measures are recommended for this population as it will probably survive habitat alterations. It is possible that some pools in the de-watered channel would become habitat for resident fish. Fishermen using such pools should be protected from sudden releases of water from the dam. The natural alluvial channel below the powerhouse and lower gorge on West Creek should be maintained so that fish migrating upstream from the Taiya· River have access to the small tributary entering West Creek below the bridge from the north. It appears unlikely that such a requirement would necessitate additional mitigation beyond returning tail race water into the West Creek channel. This will be better established after a map and profile of the stream section is completed. -77- The proposed West Creek project would provide a potential for a salmon hatchery water supply. The possibility of establishing a hatchery at the head of Taiya Inlet was discussed several years ago both by the Northern Southeast Aquaculture Association and by the Alaska Department of Fish and Game. The water taken from the lower depths of the reservoir water supply would be cold (4-60 C), poorly buffered (low conductivity, alkalinity, and hardness), and milky. These conditions, and the apparent infertile nature of the Taiya Inlet entry, could limit the usefulness of the site for a hatchery. The objectives and operation of such a hatchery must also address the species and timing of the returning run. For example, a sizeable hatchery run of late chum salmon would create serious diffi- culties in ADF&G management of the fall Lynn Canal fishery. On the other hand, an earlier run of salmon, possibly harvested in Taiya Inlet, might be compatible with harvest management strategy. The species composition and run timing which would be feasible and desirable for a West Creek hatchery must be determined before a decision is made to design and install a tap off the penstock or other hatchery water supply possibilities. Finally, there is the possibility that the tail race and lower West Creek flow route(s) could be designed so that salmon running into the Taiya River would be attracted to the channel for spawning. The concept of such a design would be to utilize a regulated (or partially regulated) flow derived from all or part of the tail race water to develop a salmon spawning channel. While this concept has been used in British Columbia projects, there has been no indication to date of support by the Alaska Department of Fish and Game or the Northern Southeast Regional Aquaculture Association for such efforts. Nevertheless, a significant potential may exist. -78- APPENDIX A-I: SELECTED PHOTOGRAPHS OF WILDLIFE SURVEY AREA AND HABITAT TYPES B. A. North wall of West Creek Valley.

APPENDIX B-1: INTERVIEW DATA 1) Burroughs, Rick -Long Bay area resident. The survey team spoke with Mr. Burroughs at his log cabin on the northwest shore of Long Bay, where he has resided for seven years. He represents part of the recent growth of Taiya valley population; pre- viously, Mr. Mathews and Mr. Patterson were the only permanent residents. Mr. Burroughs called our attention to a small debris-filled hole across the Skagway-Dyea road from his cabin. 2) Clabough, David -Ranger, Klondike Gold Rush National Historic Park. The survey team talked with Mr. Clabough on several occasions during the survey period, and on one occasion we patrolled the Dyea area with him. We visited the old Dyea cemetary and discussed the amount and rate of erosion that has been taking place in the vicinity of the cemetary and the native village site that is reported to be in the area. He was also able to provide general information on the gold rush era houses/cabins that are still occupied in the area, and on the location of visible remains of DKT Company activity southwest of Dyea. 3) Elliott, Skip -Dyea area resident, Skagway city manager. We met with Mr. Elliott in his office at the Skagway City Hall and discussed a map he had located in old city record books that indicated there were mining claims in upper West Creek valley. He felt that most would be well above the proposed project area. Mr. Elliott had made several unsuccessful attempts at trying to locate the claims. When asked about a possible historic native trail route from West Creek basin into the Haines area, he said a traverse would be possible, but the route would be very difficult. Mr. Elliott's familiarity with the West Creek drainage was a great asset in evaluating the potential for cultural sites in the area. In addition to the possible mining claims in West Creek, Mr. Elliott noted that the entire ridge south and east of Skagway was covered with mining claims, even though there is no gold there. 4) Hosford, Fred -Skagway resident. Mr. Hosford's father logged in the,Taiya River valley from the 1940's into the 1960's and the family owns property at West Creek near the powerhouse and tail race. The sheds and debris in the powerhouse area date from the 1950's. Mr. Hosford remembers the larger shed being occupied by an elderly man in the late 1950's, early 1960's. The evidence of logging in the powerhouse site and transmission corridor was done by the Hosford family in 1965. 5) Kalvick, Alf -Dyea area resident. The Kalvick's live on the main road near the junction with the road to the powerhouse. They have built their home, outbuilding and other improvements in four years. Their property backs up to the McDermott property to the east. Mr. Kalvick was able to provide information on gravel depth from information he. gained while putting in his well. He also provided information on the construction methods of the main road. Over the course of the survey several visits were made to the Kalvick's and stories of the area were enjoyed around the fire or at least out of the rain. 6) McDermott, John and Lorna -Dyea area residents. The McDermotts live in an 1898 log cabin along the Chilkoot Trail. The cabin has been modified and some major repair work has been done. The area around the cabin has been cleared and fenced for gardens and animals. The cabin has been occupied only periodically .over the years, but appears to be well-maintained. The McDermotts confirmed the location of the historic Kinney Bridge to the north of the cabin on the east side of the Taiya River. 7) Rapuzzi, Bob -Skagway resident. Mr. Rapuzzi described an historic native trail that ascended the south side of West Creek and traversed the mountains to the Chilkoot and Chilkat drainages (Haines area). He did not know how frequently the route had. been used, but indicated there were some rugged sections. Mr. Rapuzzi was not familiar with possible past military activity on the north side of the Skagway River, but indicated activity in that area was sparse in the 1890's. Development of the north side of the river occurred in later years, primarily after the construction of the Skagway-Dyea road. At one time, there was a cable which crossed the Skagway River near the 3.0 milepost. Mr. Rapuzzi indicated that the rock quarries along the southern edge of Yakutania Point were used to obtain fill material for the Skagway tide flats. 8) Selmer, Elizabeth -Skagway resident. Contact was originally made with Ms. Selmer to obtain information about her 4-acre property west of the Skyline Trail. Ms. Selmer originally improved her property to receive a patent, but her cabin burned some years ago. She indicated the shed located near the Skyline Trail was also constructed by an individual seeking to patent the area. Ms. Selmer recalled that the cables evident near the Skagway River were originally part of a suspension foot bridge. She thought the bridge was removed when the present Skagw~y airport was expanded. The only sign of military activity Mrs. Selmer recalled was a large antenna on Yakutania Point. She commented that the military was primarily interested in the White Pass and Yukon Railroad on the south side of the Skagway River. APPENDIX B-2: MARINE SHELL DEPOSIT This small marine shell deposit does not appear to contain cultural material, however, only the exposed surface was investigated. The road has cut into the deposit and it continues to erode. It is suggested that this deposit receive additional attention before any project activity in the area. The shell deposit is locate4 50 m south of the 8.0 milepost along the Skagway-Dyea road. The deposit is located on the top of a 3 m high rock face which was formed during road construction. An unknown amount of shell material was lost during construction. The deposit is composed mostly of mussel shells, with a few gastropods (.5 cm to 6.5 cm dia.), limpets, fish verterbrae and small bones. The visible stratigraphy of the deposit appears to divide it into three rela- tive distinct layers. The top layer is mixed with forest humus with small roots and averages 40 to 60 cm in depth. The middle layer is densely packed mussel shell and is from 10 to 40 cm in depth. The bottom layer has a variety of shell material (mostly mussel), sand, old humus, and small pieces of charcoal. This layer is from 5to 30 cm in depth. The width of the exposed deposit is approximately 5 m, ,but all three layers do not extend the entire width. While the surface of the site is under a dense moss and humus cover, its approximate size is estimated to be 3 to 4 m2 • The deposit is about 3 m above the road bed which is 2 m above the river level. It should be noted that these measurements are not referenced to the mean tide level. While this deposit is within the transmission line corridor, the small size and close proximity to the road make it easy to avoid. If there 'will be any disturbance to the area, further investigation should be considered.
