Overburden at the Site consists primarily of glacial tills, outwash, and alluv- ium with boulder and gravel zones, although significant rock talus exists on the valley slopes in the damsite area. Previous investigations have determined the following general stratigraphy from the surface downward in the reiict channel areas. These general conditions may not prevail over the entire area of invest- igations~ and variations will not be basis for claims or "change-of-conditions" claims~ and indeed one of the objectives of this work is clarification of existing overburden and bedrock conditions. 14 D Surficial Deposits Organic silts and sands with cobbles and boulders. Outwash Silty sand with gravel and cobbles. Alluvium and Fluvial Deposits Sand, silt with occasional gravel to 160 feet or more. Till/Water Lain Till Clayey silty sand with gravel and cobbles, often .plasti..cl.;. up to or exceed- ing 65 feet thick. Till Silt, sand, gravel, cobbles, poorly sorted; to 60 feet thick or more. Intergl aci a 1 Sand, gravel, with occasional silt, sorted; to 45 feet thick or more. A typical cross section is given in attachment A, figure 4.5 Alternating sequences of alluvium, outwash, and till have been detected in the area. Scattered frozen ground is found and depth to bedrock varies from zero to greater than 500 feet. Copies of dri 11 1 ogs and seismic surveys from a 11 previous investigations are available for inspection at Acres upon request of the Contractor. An extracted set of documents from the seismic surveys r~ports for the 1980 and 1981 field seasons, which included work in all the areas covered under this contract, have been included as Attachment B to indicate previous work. These attachment~ are intended as an indication of the previous seismic interpretation work and do not necessarily represent actual or anticipated conditions under this contract. Previous geotechnical reports and boring logs are available for inspection at Acres offices in Anchorage and Buffalo, New York during normal business hours. The Fog Lakes Relict Channel has not been drilled, but is expected to be similar in materials to the Watana Relict Channel. The photos and sketch in Attachment A (labeled Figure 6.30) indicates the general conditions in the Watana Relict Channel 15 area. An indication of present inferred geologic conditions are shown in the figures in Attachment B. The Oamsite area constitutes a significant portion of the work. Typical conditions are shown in Attachment A by the photos labled Figure 6.18. Overburden is not expected to exceed 100 feet at any point. Heavy talus accumulations and scatt- ered rock outcrops may occur on many of the lines. 2.4 -Scope The work to be performed under this Agreement shall comprise all activities necessary to perform seismic refraction surveys .. and-ir:tte.rpretation, as detailed below. Performance shall include all work performed by the Contractor's forces, assisted by brushing~ laborer and survey support provided by Acres as specified in Section 2.9. The actual footage of seismic survey under this contract is indeterminate, but is estimated as follows: -Oamsite: -Watana Relict Channel: -Fog Lakes Relict Channel: 26,600 LF 27,000 LF 37,400 LF Tentative line locations and lengths are shown in Appendix A. The exact line locations, sequences, and length will be determined in the field by the Engin- eer. Alternative or secondary lines are shown for the relict channel areas, and are noted on the Tables and/or Figures as such. These represent additional or alternative locations which may be run in addition to or in lieu of the primary lines which form the basis for the estimated footages above. The purpose of the work specified shall be to determine; within the limits and accuracy of modern equipment, knowledge and methods; the thickness and general nature of the overburden underlying each line, and seismic velocities and variations in the upper 50-100 feet of bedrock.

Equipment, supplies, and crew will be transported to and L'Om the site in accordance with the provisions of Sect:ion 2 .. 9 at no cost to the Contractor. {a) Mobilization Mobilization will be considered complete when all personnel and all associated equipment and materials necessary to commence operations are on the Site and are set up at a work site ready to work. (b) Oemobilization Demobilization will begin when seismic operations and field interpretation at the last line site has been completed and Contractor has been notified to remove his equipment .. Oemobi1ization will be considered complete when all personnel, equipment, and surplus material is removed frooi the Site and cleanup is complete as defined under Section 2.13. 3.2 -Fog Lakes Relict Channel Work to be performed in the Fog Lakes Relict Ch nnel area is estimated to total 37,400 linear feet of line, (Attachment A) in segments of about 1,100 feet each. The intent of these lines is to define the subsurface profiles of the suspected relict channels and to ascertain the probable highest point of the bedrock profile on the channel thalwegs, therefore, shifting of the lines from the locations shown may be necessary to follow the channel. At any point, a line trend may be abandoned in favor of alternative locations if it is felt to be necessary to obtain the required information. All lines shot in this area are expected to exceed l,Onn feet each. The primary objective is to determine 25 depth to bedrock, however, general intermediate and rock velocity data is also required. Accuracy as a percentage of overburder depth is critical, particularly in the deepest areas. All points along the line shall be staked as necessary to obtain accurate locations within one foot horizontally and vertically at start, end and turning points, and within 10 feet along the lines. A11 markers shall be clearly labelled with the line and point numbers. 3.3 -Watana Relict Channel The work to be performed in the Watana Relict Channel area is predominately ,~ill-in lines to tie into or supplement the 1980-81 lin.es. Total estimated footage in this area is 27,000 linear feet, (Attachment A) in straight line segments of 1,100 feet typically, and estimated line lengths of 1)100-6,600 feet. The primary intent of these lines is to obtain detailed top-of-rock profiles. All points along the line shall be staked as necessary to obtain accurate locations, within one foot horizortally and vertically at start, end, and turning pints, and within 10 feet along the lines. Lines are expected .to be predominantly straight, with not more than one or two turning points per 1 i ne. 3.4 -Oamsite An estimated 26,600 linear feet of line are to be conducted in the damsite area (Attachment A). The accurate dete rrni nation of depth to bedrock and bedrock velocity variations are the primary co.ncerns in these lines. All lines shall be staked for accuracy within one foot vertically and horizontally at critical points, and within 10 feet along the lines. Individual line segments are expected to be straight lines (in plan) at least 550 feet in length. Line segment locations will be laid out in the field by Acres prior to shooting. Minor shifts in location will be allowed to avoid excessively difficult work areas, subject to approval by the engineer. Overburden within the damsite is shallow in mort areas, with an estimated maximum depth of 1\JO feetG Contractor shall have capability of geophone spacings suitable for determining depths to bedrock from O-H10 feetc Variations in bedrock velocity across the site, which may indicate fractured, sheared and 26 J, tli i ] .I I '"-"' I ' ' i lll! J • 1 I I i i ~ 4 ' 1[11i ' ·I . 11 I . i faulted areas, shall be specifically noted and investigated in detail, as approved by the Engineer. All points along the line shall be staked as necessary to obtain accurate locations within one foot horizontally and vertically at start, end and turning points, and within 10 feet along the lines. 3.5 -Interpretation Field interpretation shall define; within the limits imposed by field conditions, lack of survey, and the unadjusted sei.smi~ _r:ecords; the approximate overburden velocity, top of bedrock location, and approximate bedrock velocity variations. Significant detail is expected with respect to bedrock conditions in the damsite area, whereas a more gener·al conditions interpretation similar to that of Appendix R is acceptable in the relict channel areas. Computer refinement and interpretation simi 1 a r to that performed in the 19RO-Rl surveys shall be used under this contract, with refinement and application of experience and judgement being performed by the chief interpreters for the draft and final reports. These reports shall be prepared under the direction of, and be signed by, and experienced re£;isteted geophysicist. 3.6 -.Reporting (a) A daily field progress report shall be provided to the Engineer, listing work accomplished for that day's shift, with quantities claimed under each pay item. This report, which may be on simple fill-in form, shall be signed by the Engineer and the Contractor's Field Representative, and will constitute the record of field contract services when signed by both {b) (c) parties. Field interpretation shall be performed as specified in sections 2.4, 2.R, and 3.S and provided to the Engineer in rough field format understandable to a geologist or engineer. The Contractor shall provide three ccpies of a draft report, complete in 27 all essentials but without completion of editing, proofreading, or fina.l minor interpretation changes, to Acres by November 1, 19R2.

(b) Payment as defined under Sections 4.3, 4.4, and 4~5 will be made only up to a maximum combined total of 12 hours per shift per crew. In no case wi 11 payment be made for cumulative tot a 1 charges for the sum of Items 3 and 4 of the Schedule in excess of 12 hours per shift for each crew, unless approved in writing by the Engineer. (c) For each crew, if any payment conditions defined in Sections 4.1, 4.2, 4.3, 4.4 and 4.5 occur on the same day, payment will be made according to the following priority only for the period of time said payment conditions occur simultaneously: ( i ) ( i; ) ( i i i ) (iv) (v) First, for conditions defined under Section 4.1; Second, for-conditions defined under Section 4.2; Third, for conditions def)ned under Section 4.3; Fourth, for conditions defined under Section 4.4; and Fifth, for conditions defined under Section 4.5. For each crew, no payment shall be made under more than one of the payment conditions even though more than one of these payment conditions may occur simultaneously. (d) Statements with copies of signed shift reports and all applicab\e invo1ces for expenses must be submitted monthly, in accordance with Section 1.12 of th;s ~greement. 34 (e) If this contract is terminated Acres will pay the Contractor at the rates stated in the Schedule for work completed. Acceptable partially completed work will be paid at direct cost to the Contractor, based on audited invoices, pay and overhead costs~ Unacceptable incomplete vwrk will not be paid for • ....... _ (f) When performing under Section 4.3 or 4.4, and subject to approval of the Engineer, crews may be combined for joint operations to increase efficiency. Payment·for·combined crews will be made as if the crews were working independently. (g) Upon successful completion of the field work required for the seismic lines and acceptance of the contractor•s preliminary field interpretation by the engineer, Acres will pay the contractor 65 percent of the app- licable rates stated in schedule C-1. Acres will pay the contractor the remaining 35 percent upon acceptance by Acres of the final inter- pretation and report preparation. Acceptance of the contractor's preliminaFy field'interpretation by the engineer does not guarantee acceptance of or payment for the final interpretation or report. (h) For purposes of initial payment following the completion of field work, the length of seismic lines run in the Watana and Fog Lakes relict channels will be based on the measured distance (either taped or taken from maps) along the completed lines as approved by the engineer. Upon completion of survey work the exact length of all lines (as measured in horizontal projection) will be calculated and the payment quantities adjusted accordingly. 35 C! ,<0 I,,, ATTACHt·lEiH A SITE AND PROPOSED vJORK LOCJ\TION PLAN ATTACHMENT A SITE AND PROPOSED WORK LOCATION PLAN The fo 11 owi ng documents are provided in this at tach men t , showing the 1 oca- tion and extent of proposed work.

These surveys were performed under contract with· R &-M Consultants ( R & M) as part of their subcontract ·with Acres American Incorporated (AAI). The 1981 geophysical program was easentLa~y a continuation of surveys performed during 1980 under the same contract. Results of the 1980 surveys were submitted to R & M in a report dated 19 December 1980. Interpretations included in this report are based in part on the 1980 work, on prev1.ous seismic refraction surveys (Dames and Moore, 1975; Shannon and Wilson, 1978), and on limited boring and surface mapping information. Locations of all refraction traverses from 1975 through 1981 are shown in Figures 1, 2, and 3. Figure l covers the immediate area of the proposed Watana Dam site and Figure 2 shows line locations outside of the immediate site area but in the same vicinity. Figure 3 shows line locations near the proposed Devil Canyon Dam site. 1.1 Purpose Geophysical surveys from 1981 and from past years were accomplished as part of feasibility studies for the Susitna Hydroelectric Project proposed by the Alaska Power Authority. Seismic refraction and limited magnetometer surveys were intended to investigate the nature and distribution of bedrock and overburden materials and to supplement dat~ from other sources such as borings and geologic mapping. , n ~ ' fl '. :ciw lC c. l-2 For all surveys run during 1980 and 1981, line locations were specified by AAI. Some of the 1981 locations were recommended by Woodward-Clyde Consultants at the close of the 1980 season, and incorporated in the 1981 program. 1.2 Scope A total of 7 21 900 ft of refraction line was run in 1981 during three separate f.ield effo~ts (spring 1. summer, and fall) to bring the two-year totai"·· to approximately 1001 ooo· linear feet. In addition, approxima_tely.-~000 ft of magnetometer line was run near Devil Canyon in an unsuc- cessful attempt to detect buried mafic dikes. The spr1ng seismic refraction survey consisted of 21,900 ft of line at 12 locations (Lines 81-1 through 81-12) across the river and adjacent low-lying areas near the Watana site (Figures 1 & 2). Field work was accoinplisheo between l April and 14 April 1981 when the river was frozen. The low water level and low water velocity plus access afforded by ice allowed refraction surveys to be run in areas where they would be infeasible later in the year. A draft report of the results of the spring work was submitted to R & M dated 18 June 1981. A total of 22,200 ft of refraction line was run during the month of July as 10 separate traverses (Lines 81-13 through 81-22). Nine of these were run at the Watana site (Figure l), some as continuations of existing lines. One traverse was run on the proposed south abutment at Devil Canyon (Figure 3). From 26 October to 15 November, 1981, a 28,800 ft traverse was run from rock outcrops uear the proposed \"latana south abutment to a point approximately 5 miles to the east.

A Geometries/Nimbus model ES-1210E' twelve-channel stacking seismograph and an explosive energy .. source was used for all lines~ Line lengths and geophone spacing varied as-discussed later in separate sections. Data reduction for the 1981 surveys .. was.--accomplished in a similar manner as for the 1980 lines~ essentially following the procedures of Redpath (1973). Rigorous delay time methods were used for: only a few lines for which data was sufficient and teo complex for adequate interpretation by approximation methods. Time-distance plots of the data are included in Appendix A (spring surveys), Appendix B (summer surveys), and Appendix C (fall-Fog Lakes surveys). Interpreta'"cion of these lines are shown as Figures 4 through 23 and are discussed in Sections 4.0, 5.0, and 6.0. These sections discuss the setting of each traverse, our interpretation, and anomalous or ambiguous condit.i.ons which became apparent during data reduction and subsequent review of all available data. Our conf~d~nce in the contacts between layers of differing velocities on the figures is variable. Solid lines repre- sent well controlled contacts with the depths shown prob- ably within 20 percent of the true total depth. Dots on a line represent depths calculated by the delay time method or by approximation techniques. Dashed lines are less well controlled with an estimated possible deviation from true depths on the order of 30%. Queried dashed lines are 2-2 assumed contacts that are based on assumed velocities and information other than that resulting directly from data reduction, or that are inferred by the data but are not mathematically explicit. ~~ ,. l'"'l r ~:' \ :, 3" J LIMITATIONS Seismic refraction is a widely used and well suited exploration tool for engineering projects but is subject to certain limitations which should be kept in mind when evaluating the . interpreta·tions presented in the following sections D The effects of inhomogeneities I irregular contacts, .. blind zones 11 and hard:...over-soft conditions are discussed below. Othe-r limit(:·tions which result from the site environment and from the sp_ecif.i.e..d. scope of these surveys apply particularly to seismic work performed at the Susitna sites. The seis~ic refraction technique depends upon measuring the first arrival of a seismic wave at geophones placed on the ground surface progressively further tram an explosive charge or other seismic source. Arrivals at nearest phones generally indicate travel directly through low-density surface materials. At points further from the source, the seismic wave arrives sooner than would be expected from travel through surface materials, having traveled in part through deeper, more dense, and therefore higher velocity layers. If subsurface layers are uniform, horizontal and the seismic velocities progressi-v-ely increase with depth, a mathematical model can be developed from the arrival time data that approximates actual conditions. Several condi- tions exist in nature, however, which make interpretation of the data less precise and introduce ambiquity into the model. ln ideal situations, plots of arrival times versus distance (see Appendices A, B, and C) produce straight lines, the inverse slopes of which represent the seismic velocity of the subsurface material. Deviations of the data from straight lines indicate inhomogeneity within layers, !) 3-2 irregular layer contacts, or inaccuracy ~n identification of first arrival time. Sufficient data is seldom available to distinguish amoung these possibilities. It is also difficult to determine if irregularities occur in near- surface layers or at depth. In many cases, the data resulting from local or lateral velocity changes can· alsd be interpreted as contact irregularities. Thin layers at depth also present a problem~ Ideally each layer is represented on a time-distance ··plot-as a separate stra~ght line, Thin layers may produce no indication of their existance in the data regardless of the detail of the survey. Such 11 blind zone .. cases can affect the calculated depth to deeper layers, such as bedrock, by a theoretical maximum of 30 percente Layers with seismic velocities less than overlying layers are not detectable by refraction. This situation is suspected i:.o exist in several areas, at the Watana site in particular, where less dense sediments may underlie frozen, more dense ground. Non-seismic information, such as boring data, is required to resolve hard-over-soft conditions, enabling correction of the refraction model, which is otherwise likely to be in error by as much as 30 percent for the depth of deeper layers. Several conditions occur which preclude collection of the optimum quantity and quality of data. These include weather: ground conditions and, of course, the time available to resolve operational problems which may arise. For the Susitna work, field data reduction was performed to assure the sufficiency of results from each line. In some cases, however, time and budget constraints precluded running additional lines which may have resolved some uncertaint.i.es. ! ~ :cJ l : .01 l 3-3 In interpreting data which is less than straight forward, the tendency is to produce as simple a model as possible without violating the restraints of the data. In these cases, the experience and judgement of the interpreter is important in producing a geologically reasonable picture. The presence of an experienced geologist during shooting of the lines and during interpretation, combi~ed with the results of previous investigations, increased the likeli- hood that profiles presented herein reflect a fairly accurate model of existing conditions suitable for evalua- ·4··-- tion of the feasibility of the project. Further explora- tion is required to resolve the uncertainties identi- fied during these surveys. . i .J t Lt ....... 5.0 SUMMER 1981 SURVEYS Traverses 81-13 through 81-19 were located on the north side of the river, upstream from th~ proposed Watana Darn. This area is under lain by a buried or 11 relict" channel. Velocities of channel fill material. vary considerably ·as discussed in relation to the individual t·raver·ses below. From borings discussed in the 1980 report (Woodward-Clyde Consultants, 1980) , these rna terials are known to include well consolidated glacial tills-an·d--outwash deposits, younger alluvial deposits, and some lacustrine sediments, all possibly frozen in part or entirely. Alth~ugh the seismic velocities of the channel fill referenced with each traverse are a reflection of material properties, no subsurface boring data was available in the vicinity of the 1981 traverses to identify the type of material that migh,t be represented by a particular velocity range. Traverses 81-20 through 81-22 were run in areas of shallow bedrock on the south abutment at Wat.ana and on the south abutment at Devil Canyon. For these as well as for the other lines, higher velocity bedrock (ie 15,000 to 20,000 fps) is presumably more competent than lower velocity bedrock (ie 10,000 to 14,000 fps). Specific rock types or degrees of weathering, however, cannot generally be distin- guished by velocity alone. Correlation of the seismic velocities reported herein with the most recent surface · mapping and boring information may provid~ a better idea of the extent of particular mapped units and struc- tural features away from their locations known from out- crops or cores. 5.1 Traverse 81-13 Three 1,100 ft geophone spreads overlapped line 80-1 by 500 f·t and continued that traverse an additional 2, 800 ft to 0 5-2 the northeast as shown in Figure 1. The traverse crosses undulating topography which rises gently to the: northeast. The interpreted profile of traverse 81-13 {Figure 10) shows a continuation of the relict channel with a relatively uniform depth toward the northeast end of the line where it shallows. Bedrock, with s.eismic velocities ranging from 13,000 to 15,000 fps is from 200 to 250 ft deep beneath most of the traverse. Channel fill rna teria_l ranges from 6,000 to 8,000 fps and surficial sediments, which are thicker toward the southwest end of .the ... l.in.e \vhere it overlaps 80-1, average 2, 200 fps. Several irregularities in the time-distance plot (Figure· B-1) appear to be d.ue to topographic effects. 5.2 Traverse 81-14 The southwest end of traverse 81-14 is located about 600 ft from the northeast end of traverse 80-2. Three 1, 100 ft lines were used to extend traverse 80-2 to the northeast. The n9rthern end of the line turns north tc the edge of a small lake as shown in Figure 1. Relatively smooth topo- graphy rises gently to the northeast to within 1,000 ft of the small lake, then drops gently toward the lake. The t.cpography along the northern 1, 000 ft was not surveyed i the profile shown in Figure 11 for that area was approxi- mated from small scale maps and field notes. The interpretation of traverse 81-14 (Figure 11) shows 18,000 fps bedrock to be 500 ft deep beneath the southwest end of the line. This requires a drop of about 200 ft from the northeast end of line 80-2 which is not inconsist .. ent with the 19:30 interpretation. The 500 ft depth places the thalweg of the channel at an elevation of about 1;700 ft, which is similar to that found on line 80-1 to the west and somewhat de,=per than on lines to the southeast. This -' ~ \\ .. 1. , .I "t ~ i : . I ;l I L~ 5-7 east side of the traverse to produce more detailed data in that araa. Gently rolling topography along the traverse rises slightly toward the east. Figure 15 shows that bedrock, interpreted to be about 18,000 fps, under.lies the entire traverse at shallow depth, generally less than 10 ft. A srnal~ wedge, up to 50 ft thick, of intermediate velocity material, averaging 7,000 fps overlies bedrock near the east end of the line. This material was identified as varved silts and clays in b or i n g D H-2 5 ( U . S . Army Co r p s -o .f .. E ~ i n e e r s , 1 9 7 9 ) o 5.9 Traverse 81-21 Four overlapping 550 ft geophone spreads and several 225 ft detail spreads were run across the suspected projection of the Fingerbuster structural feature on the south abutment of the proposed Watana Dam. The total length of the line was about 1900 ft. It crosses line 81-20 near its northeastern end. The topography rises steeply to the southwest along the traverse. The purpose of traverse 81-21 was to delineate, if possi- ble, the Fingerbuster zone in order to locate a drill site for further exploration of the zone. As shown on the interpretive prof i 1 e of the travers e ( E· i g u r e 1 5 ) , the structural zone appears to occur as an area of 12,000 fps bedrock flanked by more competent 18,000 fps bedrock. This is overlain by 1,500 to 3,500 fps surficial materials which range in thickn··]ss from zero to 40 feet. The location of the zone was thought to be known more precisely from apparent anomalies on field time distance plots. Several anomalies apparent on the time-distance plot (Figure B-·6) , can be attributed for the most part to topographic irregularities and to changes in thickness of .. . j .. \._ L ' 1 ; ~ i Lt I I. lc.J l 5-8 the near surface layer. The zone appears to be delineated by a prominent slope bre~k to the west and a rapid thinning of surficial deposits to the east. It appears that a topographic low exists over the central portion of the zone. The depression appears to be due to erosion by a crossing stream. 5.10 Traver~e 81-22 This traverse was run as three overlapping 550 ft geophone spreads along the ridge on the south abutment of the proposed Devil Canyon Dam. The eastern portion of the traverse crosses the southern ends of lines 80-12 and 80-13. The somewhat irregular ground surface along the traverse slopes do\Alnward toward the east end . The interpretive profile of traverse 81-22, shown in Figure 16, shows very shallow bedrock ranging from 11,000 to 15,000 fps overlain by surficial materials of 1,800 to 2, 000 fps. The surficial material appears to average about 10 ft thick but thickens to as much as 30 ft at one location near the east end. Intermediate layers of 5, 000 and 10~000 fps interpreted for the south ends of 80-12.and 80-13 were not apparent from the data for 81-22. .··~ l. L ' ·ll : LJ l. ~--t':_ ) '' ...J 6.0 FALL TRAVERSES-FOG LAKES AREA The Fog Lakes traverse consisted of 48-500 ft geophone spreads with common· end shot points. The location of the traverse was selected to cross areas of possible buried channels which could contribute to seepage from -the reservoir. Topography along the line is gently rolling and relatively flat loca~ly. Elevations r~nge from less than 2, 300 ft across the Fog Lakes valley, approximately five miles east of the proposed Watana Dam, to about 2, 400 ft ~ ~ .. ·-- near the proposed south abutment. The interpretation of the data for the traverse, shown in Figures 17 through 23, indicates that apparent bedrock velocfties vary substantially along the traverse, from 20,000 fps to as low as 10,000 fps. Two types of intermediate material are apparent. The first ranges from 4, 500 to 7, 000 fps and is interpreted to consist of poorly consolidated, saturated glacial deposits. The second ranges from 8, 000 fps to as much as 10,500 fps. This is suspected to be well consolidated glacial sediments in part or entirely frozen. Surficial deposits range from 1,000 to 3,000 fps, are as thick as 50 ft in some areas, and are absent in others. Several areas along the traverse appear to be underlain by buried channels which extend below the proposed reservoir level. The two most prominent of these are near the west end of the traverse (Figure 17) and beneath t:1e Fog Lakes Valley (Figures 22 and 23). Near the west end, a channel which may be as deep as 300 ft (to ~levation 2,030) is filled mainly with low velocity (4300 to 6000 fps) de- posits. Higher velocity channel fill (9000 fps) is indi- cated near the east side of the channel but the contact I. l l .. L )..J I ' . .....) i 6-2 between the two types of channel fill is uncertain. It is possible that the higher velocity material is permafrost, in which case unfrozen sediments (with lower velocities) could be present below it and the total depth of the channel could be somewhat less than shown on the profile. The width of the deepest part of the channel appears ·tO be about 1,000 feet. The apparent channel in the Fog Lakes Va~le¥·i~-more than a mile wide. The deepest part appears to underlie the lowest part of the valley at an elevation of about 1,940, 350 ft below ground surface. Much of the rest of the channel, which extends below the topographic high northwest of the valley, is below an elevation of 2,100 feet. The shape of the channel shown on the profile is based on marginal arrival-time data from distant offsets and from minimum depth calculations where distant offsets did not penetrate sufficiently to detect rock. The shape, therefore, could be significantly different, especially on the west side where depths could be greater. The interpretation shown, however, is considered to be a reasonable estimate of the maximum depth within the Jimits of the uncertainties of the data. The most critical uncertainty is the nature of the 8, 000 to 11,000 fps apparent channel fill material. If this material is interpreted to be well consolidated glacial deposits then the interpreted profile as shown in Figures 22 and 23 is appropriate. However, if the material is frozen, then lower velocity material could underlie the perma- frost and depths to bedrock could be shallower than shown on th~? Figures. 0 L. I· l l N1 [ .jl 6-3 A third possibility, which is not likely, is that the apparent channel fill could instead be weathered bedrock, at least in part. If this were true the bedrock velocity would be so close to that expected for frozen or well consolidated sediments that the contact between them could not be distinguished. It is remotely possible that the apparent iridications of high velocity bedrock at depth are the result of irregularities in shallower, ·very low "Jelocity weat.hered rock or from steeply dipping contacts between v1eathered bedrock and higp Y.~.)._ocity channel fill. An a~tempt was made to resolve the nature of high velocity apparent channel fill material using shallow reflection at ~he location of refraction line 81-FL-3. Results were r.aot definitive but the t,:ost likely reflection appears to place the bedrock contact at a depth of 170 ft beloy.r ground surface which is similar to the depth indicated by refraction in that area. This depth, however, indicates an anomalous high near the middle of the broad channel which makes the interpretation even more tenuous. Other areas of apparent channeling are present along the central portion of the traverse. These chanr .... ::.s, although broad in some cases, are all above eleva~ion 2,150 and generally shallower than elevation 2,200. At several locations along the Fog Lakes ~raverse, bedrock lows appear to coincide with higher seismic velocities which is contrary to conditions elsewhere in the vicinity. No explanation for this is evid•.~:Jt from the present data. -~--~-~~-·----~--·--~-·--·--·-··------~~--''· .· \\ •; .. - 1-w I' z 0 22QO 2100 ~ 2000 > w ..J w 1900 ..... ·r ........ .
