EVALUATING CULTURAL RESOURCES ASSOCIATED WITH THE CENTRAL INTERIO~ ALASIA Report by University of Alaska Museum Archeology Department Prepared for Alaska Power Authority Draft Report May 1984 I DRAFT '• I I I I I I I I I I I I I I I I ll I 1 -INTRODUCTION 1.1 -Scope Federal agencies are required to assess the effects of projects, such as the Susitna Hydroelectric Project, on properties on or eligible for nomination to the National Register of Historic Places. When such properties will be adversely affected, the agency must determine whether there are feasible and prudent alternatives which would avoid or satisfactorily mitigate the adverse effect. The eligibility of a site or group of sites, for inclusion in the National Register, is based on the significance of the site(s). Therefore, it is first necessary to determine site significance. The significance of a site is directly related to its potential to answer research questions. This report summarizes the assessment of site significance through defining the concept of significance, identifying pertinent variables, and presenting research questions relevant to the study area. Section 2 addresses the determination of site significance from legal and scientific perspectives. Legislation relating to site significance· is discussed and professional concerns on the definition of significance are presented. Section 3 presents the variables recorded for each site. These data form the basis for determining the relevance of a site to a particular research topic. The method of recording data and a explanation of the variables are presented in the Procedures/Quality Assurance Manual (Revised 1984). 1-1 DRAFT I I I I I I I I I I !Ill I I I I I I I I I I ---- Section 4 presents research questions grouped according to five major research areas. These areas are: 1) Cultural Chronology, 2) Possible Effects of Tephra Falls on Prehistoric Human Ecology, 3) Subsistence and Settlement, 4) Population Dynamics I Exchange and Diffusion, and 5) Ethnography and History. Additional research topics may be generated as a result of evaluating the questions and the collection of additional data through continuing fieldwork. 1-2 DRAFT I I I I I I I I I I I I - I - I I I 2 -SITE SIGNIFICANCE The federal mandate to manage and protect archeological and historical resources has historically divided cultural properties into two classes: those which are "significant" and those which are not (Tainter and Lucas 1983:707). The definition of significant archeological resources is a controversial and much debated concept in archeological and le~al communities. The complexity of the concept of significance has been discussed and evaluated in a number of reports and articles (Anderson 1972; Scovill et al. 1972; House and Schiffer 1975; Moratto 1975; Glassow 1977; King et al. 1977; Moratto and Kelly 1977; Raab and Klinger 1977; Schiffer and Gumerman 1977; Schiffer and House 1977; Sharrock and Grayson 1979; Barnes et al. 1980; Tainter and Lucas 1983). This section will outline the history of significance from legal and scientific standpoints to explicate how the concept of significance is implemented with respect for archeological sites associated with the Susitna Hydroelectric Project. Effective evaluation of the concept of significance can be accomplished by dividing it into types. In principle, the process of assessing significance is relatively straightforward once there is agreement on the types of significance that needs to be considered. One first specifies explicit criteria for judging resources in relation to each type of significance. Then the fit between the criteria and the resources is evaluated. Finally, it may be desirable to arrive at an overall judgment based on a weighing of the types of significance that have been considered (Schiffer and Gumerman 1977:240). Although several types of significance have been recognized in the literature, including historical, ethnic, public, legal, and scientific significance 2-1 DRAFT I I I I I I I I I I I I I I I I I I I (Schiffer & Gummerman 1977:244-245), two are considered most encompassing and integral to our discussion. As will be shown, legal and scientific concepts of significance provide two different but interrelated perspectives. 2.1-Legal Significance The concept of significance has a long history in federal legislation relating to archeological and historic preservation. In early legislation, such as the 1906 Antiquities Act and the 1935 Historic Sites Act, the concept was equated with significance on a national level. Private preservation groups working in the early decades of this century had to come to grips with the significance concept in order· to evaluate historic buildings on their associative (association with great persons and e·.-2nts in American History) and artistic merits. This need to set standards for evaluation in historic preservation greatly influenced the further deve 1 opment of the concept of significance (Tainter and Lucas 1983:708). The first formulation of guidelines to serve as selection standards for preservation was attempted by the National Park Service Chief Historian and later released to the National Resources Board in 1934. The determining factor for selection of a historic or prehistoric site was its possession of "certain matchless or unique qua·lities" whicl1 represented large patterns of "the American story,11 were associated with the life of some great American, or associated with some dramatic event in American history (Schneider 1935, in Tainter and Lucas 1983). Subsequent guide 1 i nes is sued by a private organization, the National Council for Historic Pre~ervation, which lobbied for the congressionally chartered National Trust for Historic Preservation, 2-2 DRAFT I I I I I I I I I I I I I I I I I I' I I were based primarily on the 1934 standards, but stated more explicitly that preservation was to include sites exemplifying the achievements of aboriginal man in America or sites of outstanding scientific importance for the light they shed on this subject (Finley 1965, in Tainter and Lucas 1983). These criteria were revised and expanded by the National Trust in 1956 and are the basis for the federal attempts to define significance today (Tainter and Lucas 1983:708). As a result of two important pieces of legislation an~ a presidential mandate, standards by which to eva 1 uate the significance of sites have again been codified by the federal government. The National Historic Preservation Act (NHPA) of 1966 established the National Register of "districts, sites, buildings, structures, and objects significant in American history, architecture, archeology, and culture" (Public Law 89-665; 80 Stat. 915; 16 U.S.C. 470s Section 101). Under the provisions of this law, consideration must be given to any National Register or National Register eligible site, structure, or district which is to be adversely affected by projects utilizing federal funds. Also with the passage of NHPA, resources of regional, state, and local as well as national significance gained protection under the law. The importance of the National Register was strengthened by the signing of Executive Order 11593 in 1971. This directive ordered federal agencies to 1 ocate, inventory, and norni nate to the Secretary of the Interior a 11 properties under their jurisdiction or control that appear to qualify for listing on the National Register of Historic Places (E.O. 11593). Implicit in the order is the notion that properties must be significant in order to be 2-3 DRAFT I• I II I I I I I I I I I I I I I I I I I I nominated to the National Register, as pointed out by Tainter and Lucas ( 1983: 709}. In 1974 another key piece of legislation deal·ing with significant properties, the Archeological and Historic Preservation Act, was passed. It amends the Reservoir Sa 1 vage Act of 1960 which provided for the preservation of historical a~nd archeological data that might be lost as a result of dam construction (74 Stat. 220; 16 U.S.C. 469}. According to an amended section of the 1974 law, Whenever any Feder a 1 agency finds, or is notified, in writing, by an appropriate historical or archeological authority, that its activities in connection with any Federal construction project of federally licensed project, activity, or program may cause irreparable loss or destruction of significant scientific, prehistorical, historical, or archeological. data, such agency shall notify the Secretary (Secretary of the Interior); in writing, and shall provide the Secretary with appropriate information concerning the project, program or activity. (Public Law 93-291; Stat. 174) The law further states that recovery, protection, and preservation of the data must subsequently take place. Criteria by which to assess significance in compliance with the federal laws and Executive Order 11593 appear in the Federal Register in 1976 and have been worded to provide for the inclusion of a diversity of cultural resources on the National Register of Historic Places. According to the National Register criteria of evaluation, the quality of significance is present in historic and archeological propertJes that 2-4 DRAFT I I I I I I I I I I I I I I possess integrity of location, design, setting, material, workmanship, feeling, and association, and (a) That are associated with events that have made a significant contribution to the broad patterns of our history; or (b) That are associated with the lives of persons significant in our past; or (c) That embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that represent a significant and distinguishable entity whose components may lack individual distinction; or (d) That have yielded, or may be likely to yield, information important in prehistory or history (CFR 36:60.6). Criterion (d) is generally used in nominating archeological sites to the register. Tainter and Lucas ( 1983) observed that the hi story of the concept of significance is rooted in legislation passed in the early decades of this century in response to concerns of arch i tectura 1 preservati ani s ts. The criteria stated above are very broad with regard to assessing the scientific or research value of archeological sites. Some aid in detei"mining significance is, however, provided in a handbook, Treatment of Archeological Properties, published in 1980 by the Advisory Council on Historic Preservation. The council was established by the NHPA to act in an advisory capacity in. reviewing proposals for archeological data recovery projects. In their handbook principles guiding the Council •s staff in their review process are set fort~. One of their major pri nci p 1 es states that properties draw their archeological value (significance) from the "assumption that they can be used fruitfully for research 11 (Advisory Council on Historic Preservation Jl 1980:6). One of the stated intents of the National Historic Preservation Act I I I is "to insure future generations a genuine opportunity to appreciate and enjoy the rich heritage of our (Pub1i~ Law 89-665, Preamble). Archeological research which addresses significant questions about the past is viewed by the council as being in the public interest, and thus fulfills this intent. 2-5 DRAFT I I I I I I I I I I I I The crucial role of research potential in assessing archeological significance is also docume·nted in the Federal Register among the regulations to be employed in complying with the Archeological and Historic Act of 1974. Significant .... cata, as used by the Act, are data that can be used to answer research questions, including questions of present importance to scholars and questions that may be posed in the future (36 CFR 66.1). These additional guidelines, set within a scientific framework, allow archeologists to more effectively gauge whether or not a site or sites have "yielded, or may be likely to yield, information important in prehistory or history" (CFR 36 60.6). 2.2 -Scientific Significance Scientific significance is an outgrowth of legal significance as stated in federal antiquities legislation over the past century and more specifically s i nee 1976 when the Fed era 1 Register set forth criteria for s i gni fi cance pursuant to the Historic Site Preservation Act of 1966, National Environmental I Policy Act of 1969 and Executive Order 11593. This legislation is very open . I I I I I Jl II ended and subject to a wide r~ange of interpretations (Raab and Klinger 1977) . A general consensus in the ar·cheological discipline has been reached in interpreting· the legislation. House and Schiffer (1977) state that significance of archeological sites is best a~sessed by scientific significance. They further argLie that scientific significance is best evaluated by research potential. This position is also supported by Raab and Klinger who ". • • fee ·1 that the best approach to assessing a rchaeo 1 ogi ca 1 significance is in relation to explicit, problem-oriented research designs 11 (1977:632). This same position was subsequently adopted by other 2-6 DRAFT I I I I I I I I I I I II I I I I I I I I archeologists (Grady 1977; Lynott 1980). The assessment of archeological significance in general and scientific significance in particular might best be taken from Schiffer and Gumerman: A site or resource is said to be scientifically significant when its further study may be expected to help answer current research questions. That is, scientific significance is defined as research potential (1977:241). The nature of research potential with regard to scientific significance is both diversified and dynamic. Basic archeological issues such as regional classification and chronology are included along with broader theoretical goals such as general anthropological principles and social scientific methods. Dixon (1977) presents an argument which suggests a broadening of archeological significance base to other areas of science such as paleoecology, marine mammals science, weather and climate, and the fishing - industry. These are all within the realm of scientific significance. One other outstanding characteristic of scientific significance is its dynamic nature. If scientific significance is tied closely with research potential, then as research designs change and methodological techniques develop, the status of significance will also change. Lynott (1980) illustrates this case . with an exa.mple from central Texas. The initial assessment of Bear Creek Shelter~ after limited testing in 1947 was essentially negative. This assessment was based upon the site's research potential to contribute to chronology building. Upon reevaluation of the site in the 1970's, research had come to emphasize questions of subsistence and settlement and the site was consequently considered significant. This same kind of issue of "future potential" is recognized by other archeologists (Glassow 1977; Dixon, in press). For instance, Glassow suggests; 2-7 DRAFT I I I I I I I I I I I I I I I I I I I ... the history of archaeology over the last two decades demonstrates that our conception of what is important to observe in the archaeological record is subject of radical change or at least significant expansion. Before the advent of concern for studying settlement patterns, for example, only "type sites" or sites with deep, large deposits might have been considered "significant", whereas today we would consider even small, ephemeral sites to be important (1977:414). The same kind of issue can be found in the archeological literature outside of a management context. For instance, Dixon evaluates the significance of artifacts from sites along the Porcupine River, Alaska, based upon context. The question of context is of paramount importance because it provides all things with meaning. Context provides parameters in which any object or phenomena may be interpreted and through interpretation becomes knowledge. Context is not limited to the depositional setting and recorded data associated with a specimen. The historic period in which the investigator functions also provides context which limits the parameters of analysis. For example, archeological material discovered. in the early 1900's is regarded differently in~the 1980's because of the advancement in analytical techniques, such as scanning electron microscopy and radiometric dating, which have expanded the contextua 1 limits of recovered material. Context must be understood as being characterized by confidence rather than as an absolute state of being. confidence is dependent upon the amount and quality of context provides (Dixon, in press). a degree of The degree of the information Tainter and Lucas (1983:707-718) attempt to sum the problem up by suggesting that because the theoretical and methodological basis of research in archeology changes, as with all empirical disciplines, we must make our own assessments with very careful detai 1 ~nd rigor~ In recapitu1ation, the significance of archeologica7 resources is best assessed within a framework of research potential given the diversified and dynamic character of the science. 2-8 DRAFT I I I I I I I I I I I I I I I I I I I 2.3 -Summary Although the development of legal and scientific concepts of significance have been discussed separately, it is clear that the two are closely interrelated and cannot be separated in actual practice. The crucial element that defines significance is research potential. This is best measured by the ability of the site data to answer current research questions. The process of constructing a framework for assessing the potentia 1 of specific sites to answer significant research questions within the Susitna River Canyon area is a complex task which involves three major steps: 1) identifying the range of variables present at the sites, 2) formulating the research questions, and 3) matching sites having the appropriate variables to specific questions. A. discussion of the first two is presented below. The third will be addressed after completion of reconnaissance level survey and systematic testing. 2-9 DRAFT t t I I I I I I I I I I I I I I I I I I I 3 -VARIABLES 3.1 -Introduction The procedures implemented during Cultural Resburces Investigation associated with the Susitna Hydroelectric Project are designed to retrieve information on three mcjor attributes of sites: location, $tratigraphic context, and artifact assemblage. A host of variabl~s by which sites can be evaluated for significance are subsumed under each cat~~gory. These variables, rangir1g from geographic and environmental context of a site to raw materials used in the manufacture of artifacts found at a site, are discussed below. 3.2 -Locational Data The site form completed for each site includes locational information telating to map coordinates, elevation, site size, terrain, vegetatio~-proximity to topographic features, and view. Map location is recorded by: 1) map quadrangle, e.g., Talkeetna Mountains; 2) the designation of the particular section of the quad, e.g., D-5; 3) the township, range, section, and quarter section description; 4) the UTM coordinates to the nearest 50 m; and 5) the latitude and longitude coordinates to within 5 seconds. The elevation of the site is recorded according to the position of the site on U.S.G.S. 1:63,360 series maps. Altimeter readings are also taken on direct impact sites within the proposed impoundments~ Two estimates of site size are recorded. The first is the observed size of the site as determined by surface artifacts and subsurface testing. The 3-1 ! I I I I I I• I ~. I I I I I I I I I I I I , ___ ----------------------------- testing procedure for determining site size is presented in the Procedures/Quality Assurance Manual (revised 1984). An estimated size of the site based upon the probable site limits as constrained by the terrain feature is also recorded. This latter value is important given the discontinuous nature of the artifact distribution at some sites, and the chancP that testing mav not reveal the limits of the entire site. .J Additional information relevant to the location of the site is provided by the terrain unit and vegetation regime present at the site. Geological terrain units as defined by R & M Consultants for the Susitna Hydroelectric Project, are used. Descriptions of the vegetation regime at the site follow the designations on the vegetation maps prepared for the Susitna Hydroelectric Project by the Agricultural Experiment Station, University of Alaska, Palmer. Sites not appearing on the above maps are assessed following the definitions of the terrain or vegetation units. 3.3 -Stratigraphic Context Sixteen stratigraphic units have been identified in the project area (Dixon et al. 1982a:5-19). No individual tests or sites have been found to contain all 16 stratigraphic units, however several archeological sites exhibit at least ten. Within any given site or site locus, subunits can be arranged in stratigraphic order. The stratigraphic units are composed of the surface organics and associated pedogenic units, four tephra units, glacial drift, bedrock, and the intervening contacts. By regarding the contact units as separate stratigraphic units, it is possible to accurately define the intervals between deposition of soil/sediment units. The four tephra units 3-2 DRAFT I I I I I I I I I I I I I I I I I I I testing procedure for determining site size is presented in the Procedures/Quality Assurance Manual (revised 1984). An estimated size of the site based upon the probable site limits as constrained by the terrain ft3ture is also recorded. This latter value is important given the discontinuous nature of the artifact distribution at some sites, and the chance that testing may not reveal the limits of the entire site. Additional information relevant to the location of the site is provided by the terrain unit and vegetation regime present at the site. Geological terrain units as defined by R & M Consultants for the Susitna Hydroelectric Project, are used. Descriptions of the vegetation regime at the site follow the designations on the vegetation maps prepared for the 5usitna Hydroelectric Project by the Agricultural Experiment Station, University of Alaska, Palmer. Sites not appearing on the above maps are assessed following the definitions of the terrain or vegetation units. 3.3 -Stratigraphic Context Sixteen stratigraphic units have been identified in the project area (Dixon et al. 1982a:5-19). No individual tests or sites have been found to contain all 16 stratigraphic units, however several archeological sites exhibit at least ten. Within any given site or site locus, subunits can be arranged in stratigraphic order. The stratigraphic units are composed of the surface organics and associated pedogenic units, four tephra units, glacial drift, bedrock, and the intervening contacts. By regarding the contact units as separate stratigraphic units, it is possible to accurately define the intervals between deposition of soil/sediment units. The four tephra units 3-2 DRAFT I I I I I I I I I I I I I I I I I I I I -------------,_,_ ___ i.Wm--~---·-•-••,.,..,-._,.:t-.t __ _, __ U_II ---~---llil!ilMmiiiiEFillll'iiliii'!FIIJ': .. \IIIIi --· are identified by local, project specific names. From the earliest to most recent they are: Oshetna, Lower Watanar Upper Watana, and Devil. The tephra units are identifiable in the field on the basis of color and texture. The region-wide occurrence of the tephra deposits make them excellent temporal horizon markers. Nine cultural horizons have been identified which can be correlated throughout the region based on stratigraphy. These zones consist of the upper level of organics, organic silts, and the contact between them, the surfaces of the four tephras, and the surface of the glacial drift or bedrock (Dixon et al. 1982a:5-19). In some cases paleqsols are present between the tephra. Dating of these paleosols asrists in establishing limiting dates for the tephra falls. The chro~ological documentation of sites and components within the project area is based upon four methods: 1) the direct historic approach, 2) radiocarbon determinations, 3) relative stratigraphic placement, and 4) typological comparisor of artifact assemblages with similar assemblages from dated sites. The nine cultural horizons can be dated within limits·, although the time span repv·esented by specific cu l tura 1 horizons may vary from a few hundred year~ to as much as 7,000-8,000 years for cultural horizon 9. Five major cultural traditions, each characterized by a unique artifact assemblage have been documented within the study area. These are: 1) Euro-American tradition (0-100 B.P.) (cultural horizon 1), 2) the Athapaskan tradition (100 • ca~ 1500 B.P.) (cultural horizons 2, 3, 4, 5)~ 3) Late Denali complex (ca. 1500-3400 B.P.) (cultural horizons 5?, 6, 7) 4) Northern Archaic traditcn {ca. 3400-5000 B.P.) (cultural horizon 8), and 5) American 3-3 DRAFT ag I _ --------~--~----~-,-------------------.. -----••••-ma··---711'8,_••• I I 1'-, . I I I Paleoarctic tradition (ca. 5000-10,500 (?) B.P.) (cultural horizon 9). Although the olde~t dated sites in the study area do not exceed ca. 7,000 radiocarbon years it is possible that human occupation in this portion of Alaska may span the last ca. 10,500 years. Due to the unlikelihood of dating all strata at every site, an emphasis is I placed upon the relative dating potential of the tephra units. The widespread I I I I I distr·ibution of the tephra deposits allows correlations to be made between all parts of the study area. The association of cultural horizons with stratigraphic units enables the construction of ~ultural components based upon the artifact assemblages of a nu~ber of sites sharing the same stratigraphic position. 3.4 -Artifacts An artifact can be considered as any object which owes one or more attributes to human activity. It can be faunal and floral material brought onto the site, structures and features, and items modified from stone, bone, wood, or • I I other raw material. The major categories of artifacts are lithic remains I which can be sorted according to materia 1 type and function, fauna 1 remains ll I I I I I flora, non-lithic artifacts, and features. Various types of lithic artifacts have been defined for the study area. These include: modified flakes, scrapers, blddes, microbladest burins, burin spalls, bifaces, bifacial preforms, notched points, stemmed points, leaf shaped points, lanceolate points, triangular points, microblade cores, microblade core tablets, blade cores, rejuvenation flakes, flake cores, 3-4 I . I I I I I I I I I I I I I I I I I I I hammerstones, abraders, and notched pebbles. The definitions of each of the tool types may be found in the Procedures/Quality Assurance Manual (Revised May 1984). Information is also recorded on the occurrence of the non-tool categories of unmodified lithic flakes, thermally altered rock, ochre, and cobbles and fragments. Eight commonly occurring types of raw material used in the production of lithic artifacts have been identified in the study area. These raw materials are argillite, basalt, chalcedony, chert, obsidian, quartz, quartzite, and rhyolite. The ... number and type of tool according to raw material are recorded ·for the artifact assemblage of each component of a site or locus. Provisions have been made for recording the occurrence of faunal remains for the variety of animals present in the Middle Susitna River Valley. Fauna include the subsistence species such as: caribou, moose, sheep, and bear; the furbearing species of wolf, fox, wolverine, and hares; and the rodents, birds, fish, and insects which may be incorporated into the site either intentionally or as a result of non-cultural deposition. Special emphasis is placed upon caribou due to the probable importance of this species in the subsistence regime. By recording the presence of specific skeletal elements, patterns of subsistence activities may be elucidated. The presence and absence of floral remains are recorded for their possible role in the subsistence round, paleoecological interpretations, and for their dating potential. Floral remains can also contribute to a better understanding of past climatic and vegetation regimes. The information 3-5 DRAFT I I I I I I I I I I I I I I I I I I I I --~-------~--------- recorded for flora consists of the presence of seeds and macrofossils and whether the material has been charred. Other artifacts made of bone/antler, metal, glass, and wood have been recovered in the study area. Features which are recorded include cultural depressions, hearths, historic structures of cabins, caches~ etc., and stone constructions such as cairns or hunting blinds. 3.5 -Summary Contextual information on the geggraphic and environmental setting, stratigraphic and cultural components, and the artifact assemblages represented by each component are major variables by which the research potential of sites in the Susitna Hydroelectric Project area is assessed. ·Additional variables will be added as required to address new avenues of research. 3-6 DRAFT ~~~~~---~----------------.-...-----------------------1!112!- I I t I I I I I I I I I I I I I I I I 4 -RESEARCH QUESTIONS 4.1 -Introduction One aspect of the Cultural Resources Survey of the Susitna Hydroelectric Project is designed to address major issues relating to the research potential, and thereby the significance, of sites within the study area~ The position of the project at the proposed linguistic juncture of the Tanaina and Ahtna (Krauss 1982) and geographir.ally located adjacent to the southern flanks of the Alaska Range, the Copper River Basin, and the lower Susitna River region allow for the study of archeology and history between groups of south central Alaska and those of the Alaskan Interior. The identification of readily distinguishable tephra units in the stratigraphy provides a unique opportunity in Alaskan archeology for the establishment of an area-wide corre 1 ati on of sites. These factors have be·en considered in the co 11 ecti on and management of data for assessing the significance of sites in the region. Five major research areas have been identified: 1) Cultural Chronology, 2) Possible Effects of Tephra Falls on Prehistoric Human Ecology, 3) Subsistence and Settlement, 4) P'opulation Dynamics I Exchange and Diffusion, ahd 5) Ethnography and History. Each major research area is discussed briefly with the major topics of interest followed by a list of questions pertinent to the topics. In order to determine which sites are appropriate for contributing to the analysis of each question, a series of required contextual variables is presented. These variables were introduced in the previous section and are available for every site which has been investigated. In addition, ancillary variables which may 4-1 I J ' I ., I I I I I I I I I I ~\ I I I I I I I 1 I I I ~-...--~-· ..,~ .... , -----~--------------------------------------- have a bearing on the interpretation of the research or may lead to other fruitful avenues of research are listed. Criteria affecting the ability of a site to address a particular research question are also presented as a means of establishing the non-significance of a site. 4.2 -Criteria of Non-Significance Factors affecting the research potential of a site are predominantly those of preservation and condition of deposits (Schiffer and Gumerman 1977:242). These factors are common to the assessment of the value of every site. Criteria for non-significance are discussed in this section rather than repeated after each question. When additional mitigating circumstances are present, they will be noted for that particular question. A site is constdered not relevant, and therefore non-significant, to the research potential of a particular question when it does not possess the required suite of variables necessary to address the topic. Sites which do possess the required variables may be geemed unsuitable due to the poor state of preservation, e.g., bone present but in the form of bone meal, o~ when the integrity of relevant stratigraphy is lacking as a result of erosion, cryoturbation, or adverse human impact. 4.3 -Chronology The chronological documentation of sites and components was reviewed in section 3.3. To date, five major cultural traditions and complexes, each characterized by specific configurations of associated cultural traits which 4-2 DRAFT I ' I I I I I I I I I I I I I I I I I I ~a I ~ persist over a long period of time have been documented within the study area. These are: 1) Euro-American tradition (0-100 B.P.) (cultural horizon 1), 2) the Athapaskan tradition (100-ca. 1500 B.P.) (cultural horizons 2, 3, 4, 5), 3) Late Denali complex (ca. 1500 -3400 B.P.) (cultural horizons 5 (?), 6, 7, 9), 4) Northern Archaic tradition (ca. 3400-5000 B.P.) (cultural horizon 8), and 5) American Paleoarctic tradition (cae 5000-? 10,500 B.P.). Issues related to how and why cultural traditions have changed are central to understanding the culture history of the region. The following questions address these issues. a) The temporal boundaries for each tradition are poorly understood with the exception of the Euro-American and the late phase of the Athapaskan traditions. Additional research is required at individual sites which fall on cultural horizons that s~ggest they hold th~ potential to document temporal limits of each tradition. i) Required variables: cultural horizons 4, 5, 8, or 9 AND datable material ii) Ancillary variables: artifact type artifact raw material 4-3 DRAFT I I I I I I I I I I I I I I I I I 11 I ,. '! iii) Criteria for non-significance see section 4.2 b) The nature and form of transitions between traditions are poorly understood in the Susitna Canyon area. Are the observed changes in artifact assemblages the result of population replacement, diffusion of artifact types, in situ development, or some combination of the above? i) Variables required: cultural horizons 2 and 5 OR cultural horizons 5 and 7 OR cultural horizons 7 and 8 OR cultural horizons 8 and 9 AND · artifact.types other than unmodified flakes ii) Ancillary variables: radiocarbon dates artifact raw material iii) Criteria for non-significance: see section 4.2 4.4 -Possible Effects of Tephra Fall~ on Prehistoric Human Ecology Evidence for four prehistoric tephra falls, occurring during an interval of at least 3,000 years from about 5,000 years B.P. to roughly the beginning of the 4-4 DRAFT t I I Christian Era, is widespread in both cultu~al and non-cultural contexts Jl throughout the Susitna Canyon area. The Susitna tephras may correlate roughly I I I I I I I I I I I I I I I : l I ~~ l in time with tephra deposits at other central Alaskan locales~ indicating a fairly extensive distribution for these ash deposits. Often overlooked in the archeological literature is the fact that emplacment of tephra on the landscape undoubtedly had some effect (positive or negative) on the prehistoric population inhabiting an area. Whether the effect was long-term and resulted in a large-scale emigration of people as suggested by Workman (1974, 1979) for the Yukon Basin, or only short-term as suggested by Dumond (1979) and Black (1981) fQr the Alaska Peninsula and the Aleutians, respectively, has yet to be resolved for the Susitna Canyon area. Environmental data, specifically data on plant and animal recovery in regions affected by historic volcanic activity and contemporary wildlife studies, can provide useful infarmation for the formulation of models with which to assess the possible impact on people occupying or utilizing the Susitna area at the time of the tephra falls. If the effects were only short-term in extent, major changes in artifact assemblages or major hiatuses in ~ite occupation would not be expected to occur in the archeological record. On the other hand, what might be expected is evidence of shifts in ~ettlement pattern or fluctuations in population density that may have resulted due to impact on the floral and faunal resources of the area. The following questions seek to address the above hypotheses on the impact of tephra falls. 4-5 DRAFT I I I I I I I I I I I I I I I I I I I :~I '1 :t ,,~ a) One effect of prehistoric tephra falls on human populations occupying the Susitna Canyon area may have been a shift in settlement.

Because of poor organic preservation at some levels it may not be possible to address some topics in more than a speculative manner. Prehistoric settlement information is probably the most abundant Kind of data obtained which relates to issues of subsistence and settlement. The most direct approach for gaining subsistence information fran, sites is the identification of floral and faunal remains in past contexts. Unfortunately, acidic soils and post-depositional transformations preserve only the most durable kinds of materials (i.e., lithir5). As a result, the amount of preserved organic remains is minimal and tnis situation escalates with progressively older occupations. Fortunately some depositional environments in the project area have allowed organic preservation. For instance, bone fragments of small mammals, birds, and caribou have been recovered at various sites. These remain~ do not allow for a reliable assessment of minimum numbers of individuals or percentage of the diet. Nor can reliable statements be made about the most preferred subsistence resource at sites. In addition to faunal remains, macrofossils of floral specimens have been recovered from some paleosols at various sites. Given the poor organic preservation, sites which do preserve organic material within and outside of the paleosol are very important. a) Is there a change in subsistence practices between the American Paleoarctic and Northern Archaic periods, and what evidence is there to support or refute this change? 4-10 DRAFT I t.l I• I I.

How far back can the use of the the region by the current groups of Ahtna and Tanaina be documented? The association of archeological assemblages with that of neighboring regions may aid in identifying the former inhabitants of the project area. The ability to segregate sites on the basis of common stratigraphy allows for~ the study of site density through time. The currently large, and expanding, data set from the project may reveal temporal trends in the occupation of the Susitna Canyon area. These trends may then be correlated with climatic change and effects of the tephra falls which may have affected the subsistence resources of the region and thereby the degree and frequency of occupation. The magnitude of tephra falls themselves may have had a demonstrable effect upon oc~upation of the project and adjacent areas. ln addition to the intensit) and duration of occupations, the introduction and transmission of items into and through the project area can he studied. Material sourcing of raw material and technological similarities with adjacent regions can provide information on the relationship of the study area to the remainder of Alaskan archeology.

Through implementation of the direct historical approach, the Athapaskan Tradition can be traced back to approximately A.D. 500 in the study area. Although ethnohistoric data have provided archeologists with useful information for interpreting sites falling within this time period, much remains to be learned about the origin, population dynamics, settlement and subsistence of these prehistoric people. Indirect impact of Euro-American culture on the Ahtna was experienc~d as early as the late 1700's, at which time iron and glass beads imported by Russian traders became available to peoples with whom the Ahtna had established trade connections (Workman 1977).
