Techno-spatial analysis of the obsidian productions at Dry Creek (Interior Alaska)
Interior Alaska is a key-region for studying long-distance circulation/use of obsidian. • This work focuses on Dry Creek, the largest obsidian assemblage in interior Alaska. • The data is the largest published sample size of source obsidian from a site in Alaska. • We analyze how artifacts from each obsidian sources were transported to the site. • We discuss the much-overlooked mid-Holocene component IV clusters. Interior Alaska is a key-region f…
Alaska Natives and Mammoths
Interactions between Native North Americans and extinct megafauna—including proboscideans (mammoths, mastodons, and gomphotheres)—tend to be portrayed only as predatory and only during a short period at the very end of the Pleistocene. In this article, we review the evidence of interaction between mammoths and Alaska Natives in subarctic/arctic North America to discuss how mammoths have held larger cultural significance both during the period of …
An inland arctic biface production site in the Northern Brooks Range (Alaska, USA)
This paper presents initial results from an exploratory ground survey and test excavation conducted near Galbraith Lake in the Atigun Valley of Alaska's central Brooks Range. Combining pedestrian survey with UAV-based aerial reconnaissance, the study aimed to identify prehistoric campsites and assess site formation processes in this inland Arctic landscape. A limited test excavation at site PSM-077 revealed a lithic assemblage dominated by biface…
Tracing past biodiversity in Central Alaska through comparative osteological identification and compound specific isotopic analysis
Northern landscapes are rapidly changing. Researchers in the region can leverage archaeological to contextualize the degree and pace of contemporary ecological change. The Klein Site on Quartz Lake offers a valuable ecological record from the late Holocene. Two occupations, at approximately 600 and 1200 years ago, reflect biodiversity before and after a volcanic eruption that arguably shifted local resources and resource use dramatically. However…
The Recent Dene History and Archaeology of Shaw Creek, Alaska
This paper discusses the critical era of cultural contact between the Dene population and Euro‐Americans during the 18th and 19th centuries at Shaw Creek in the Middle Tanana Valley, Alaska. It also provides a regional social context for the most recent archaeological component at the Swan Point Archaeological Site. The Tanana Valley represents one of the last major subarctic regions of North America to be incorporated into colonial governance, a…
Late glacial–Younger Dryas climate in interior Alaska as inferred from the isotope values of land snail shells
The isotope values of fossil snail shells can be important archives of climate. Here, we present the first carbon (δ 13 C) and oxygen (δ 18 O) isotope values of snail shells in interior Alaska to explore changes in vegetation and humidity through the late-glacial period. Snail shell δ 13 C values were relatively consistent through the late glacial. However, late-glacial shell δ 13 C values are 2.8‰ higher than those of modern shells. This offset …
Ancient Burials at Upward Sun River, Central Alaska
In the late summer about 11,500 years ago, probably in the space of a few weeks, three young Paleoindian children died and were buried in a residential camp alongside Xasaa Na’ (Upward Sun River). An infant and neonate were buried together with associated funerary objects below a central cooking hearth, and later a ~three-year-old child was cremated and buried above the same feature. This article explores the lifeways of the Ancient Beringians th…
Projectile points across the Northern Rocky Mountain front
In the recent past, the Front Ranges of the Northern Rocky Mountains formed a permeable boundary that people repeatedly crossed for trade, subsistence, or warfare, and where people occupying different parts of western North America interacted. In this paper we apply a landscape approach to study pre-contact projectile point morphologies and raw materials, and related changes in the geographic affiliations of peoples using the Billy Big Spring Sit…
Evaluating Systematic Use of Ground Penetrating Radar and Auger Surveys to Determine Activity Areas at Three Open Air Sites in Central Alaska
This study explores various testing techniques' ability to identify activity areas across deeply stratified, open air archaeological sites. To determine the efficacy of different site testing techniques, a systematic ground penetrating radar and auger survey was completed at three sites in central Alaska: Swan Point, Bachner, and Niidhaayh Na'. The results show that both ground penetrating radar and auger survey can indicate subsurface geology, i…
The Swan Point Site, Alaska
The Swan Point site in interior Alaska contains a significant multi-component archaeological record dating back to 14,200 cal BP. The site’s radiocarbon ( 14 C) chronology has been presented in scattered publications that mostly focus on specific archaeological periods in Alaska, in particular its terminal Pleistocene components associated with the East Beringian tradition. This paper synthesizes the site’s 14 C data and provides sequential Bayes…
Glacial kettles as archives of early human settlement along the Northern Rocky Mountain Front
The Northern Rocky Mountain Front (hereafter Northern Front) is a prominent geographic feature in archaeological models of human dispersal in the terminal Pleistocene and Early Holocene of North America. Testing those models has been arduous because of local geomorphological factors that tend to obliterate or otherwise limit access to archaeological finds of relevant age. In this paper, we present well-stratified archaeological and environmental …
Current Understanding of the Earliest Human Occupations in the Americas
Various chronologies of the earliest Native American occupations have been proposed with varying levels of empirical support and conceptual rigor, yet none is widely accepted. A recent survey of pre-Clovis dated sites (Becerra-Valdivia and Higham 2020) concludes a pre-Last Glacial Maximum (>26,500–19,000 cal yr BP) entry of humans in the Americas, in part based on recent work at Chiquihuite Cave, Mexico. We evaluate the evidence used to develop t…
Obsidian source classification and defining “local” in early Holocene Southeast Alaska
Despite the ubiquity of obsidian in early Holocene archaeological assemblages across Southeast Alaska, artifact sourcing using bi‐plots and Principal Component Analysis has been hampered by the highly correlated geochemistry of two major sources: local Aguada Cove on Suemez Island, and distant Mount Edziza, in the Coast Mountain range. Partial Least Squares Discriminant Analysis (PLS‐DA) models constructed with device‐specific portable X‐ray fluo…
Quantifying marine reservoir effect variability along the Northwest Coast of North America
Recognition of marine reservoir effect (MRE) spatial and temporal variability must be accounted for in any radiocarbon-based paleoclimate, geomorphological, or archaeological reconstruction in a coastal setting. ΔR values from 37 shell-wood pairs across southern Southeast Alaska provide a robust local evaluation of the MRE, reporting a local Early Holocene weighted ΔR average of 265 ± 205, with a significantly higher ΔR average of 410 ± 60 for sa…
Evaluating Claims of Early Human Occupation at Chiquihuite Cave, Mexico
Archaeologists working in Mexico recently claimed evidence for pre-Last Glacial Maximum human occupation in the Americas, based on lithic items excavated from Chiquihuite Cave, Zacatecas. Although they provide extensive array of ancillary studies of the cave's chronostratigraphic and paleoenvironmental record, the data they present do not support their central argument, that these lithic items are anthropogenic and represent a unique lithic indus…
Marine Reservoir Effects in Seal (Phocidae) Bones in the Northern Bering and Chukchi Seas, Northwestern Alaska
We explore marine reservoir effects (MREs) in seal bones from the northern Bering and Chukchi Seas regions. Ringed and bearded seals have served as dietary staples in human populations along the coasts of Arctic northeast Asia and North America for several millennia. Radiocarbon ( 14 C) dates on seal bones and terrestrial materials (caribou, plants seeds, wood, and wood charcoal) were compared from archaeological sites in the Bering Strait region…
Late Quaternary (≥MIS 3 to MIS 1) stratigraphic transitions in a highland Beringian landscape along the Kuskokwim River, Alaska
Stratigraphic records extending to Marine Oxygen Isotope Stage (MIS) 3 (57,000–29,000 cal yr BP) or older in Beringia are extremely rare. Three stratigraphic sections in interior western Alaska show near continuous sedimentological and environmental progressions extending from at least MIS 3, if not older, through MIS 1 (14,000 cal yr BP–present). The Kolmakof, Sue Creek, and VABM (vertical angle bench mark) Kuskokwim sections along the central K…
Yukon First Nation use of Copper for End-Blades on Hunting Arrows
Copper metallurgy and bow and arrow technology are widely considered hallmark traits of the Late Prehistoric Period in the northwest of North America (Yukon and Alaska). In recent years, a number of osseous arrow points have been recovered from melting alpine ice patches in the northwest, some with evidence of copper utilization. This article reports on the construction and radiocarbon dating of three osseous arrowheads recovered from Yukon-Alask…
The micromorphology of loess‐paleosol sequences in central Alaska
The middle Tanana Valley of central Alaska contains a well‐preserved record of human occupation and paleoenvironmental change since the Late Glacial period (c. 16,000 cal yr BP) and is a critical region for understanding human dispersal into the Americas. Micromorphology analysis of soils and sediments from six archaeological sites yields valuable information about soil formation processes and landscape evolution during the Late Glacial and into …
A Multiscalar Consideration of the Athabascan Migration
Genetic and linguistic evidence suggests that, after living in the Subarctic for thousands of years, Northern Athabascans began migrating to the American Southwest around 1,000 years ago. Anthropologists have proposed that this partial out-migration and several associated in situ behavioral changes were the result of a massive volcanic eruption that decimated regional caribou herds. However, regional populations appear to increase around the time…
Small mammals and paleovironmental context of the terminal pleistocene and early holocene human occupation of central Alaska
This paper explores paleoenvironmental and paleoecological information that may be obtained from small‐mammal assemblages recovered at central Alaska archaeological sites dated to the terminal Pleistocene and early Holocene (14,500–8,000 cal B.P.). Small‐mammal remains in these open‐air sites are primarily related to deposition by natural death causes and as such provide information on site paleoenvironments and landscape heterogeneity. Their pre…

Terminal Pleistocene Alaskan genome reveals first founding population of Native Americans
The Early Holocene-aged Component at the Jay Creek Ridge Site, Middle Susitna River Valley, Alaska
The Jay Creek Ridge site is an early Holocene stratified site located in the Middle Susitna River Valley in central Alaska. Two components, the Lower and Upper, were defined through several years of testing and excavation in the 1980s (1982–1983 and 1986). Accelerator mass spectrometry dating of the Lower Component indicates the site is around 11,000 calibrated years before present, placing it among the oldest upland sites in the central Alaska R…
Strontium and Oxygen Isotope Profiles of Sequentially Sampled Modern Bison ( Bison bison bison ) Teeth from Interior Alaska as Proxies of Seasonal Mobility
Studies addressing prehistoric mobility in animals typically use isotopic analyses of sequentially formed tissues, such as the growth layers in teeth, to infer physical movement on the landscape. Strontium isotope ratios (87Sr/86Sr values), which vary geographically, are particularly useful for this purpose, especially when paired with stable oxygen isotope ratios (δ18O), which vary seasonally. Together, these two isotope systems can provide info…

Testing the “Dicarb Problem”
An assumption exists in North Alaskan archaeological literature that radiometric assays produced by the now-defunct Dicarb Radioisotope Co. (Dicarb) are “too young” or more recent when compared to those produced by other laboratories. This assumption is statistically tested by comparing radiocarbon assays produced by Dicarb to those produced by Beta Analytic, Inc.; Geochron Laboratories; and the NSF-Arizona AMS Facility. The primary data set cons…
Geological and Cultural Context of the Nogahabara I Site
Interpretation of the Nogahabara I assemblage as a Late Pleistocene abandoned toolkit rests primarily on the premise of a single brief occupation at the site. The limited contextual data presented do not discount a palimpsest of noncontemporaneous assemblages in secondary contexts associated with a lag deposit. Spatial patterning, lithic assemblage patterning, artifact surface alteration, and disparate radiocarbon dates at the site, as well as ge…

The Keystone Dune Site
The Keystone Dune site, in central Alaska, contains a well-preserved archaeological occupation that dates to 13,430–13,230 cal yr BP. Archaeological excavations resulted in the recovery of features, and materials include hearths, faunal and lithic specimens, macrobotanical remains, and ocher. These were analyzed and interpreted to reconstruct past activities conducted at the site. Keystone Dune was most likely used for a short time, in the contex…
High Resolution Radiocarbon Dating at the Gerstle River Site, Central Alaska
Early Holocene cultural material at Gerstle River, central Alaska, provides excellent contextual controls for examining variability in radiocarbon dating. Over 4,000 bone and teeth fragments are directly associated with over 7,000 lithic artifacts and 10 discrete charcoal-rich hearths in a thin occupation layer (∼10 cm vertical thickness) within well-stratified loess deposits. Radiocarbon dating of the hearth features indicates overlapping ages a…

The Rosa-Keystone Dunes Field
Stabilized sand sheets and dunes hold a remarkable amount of information on paleoenvironmental conditions under which late Quaternary landscapes evolved in northern subarctic regions. We provide the results of a project focused on understanding the development of lowland environments and ecosystems, including dunes and sand sheets, which were critical habitat for early human occupations in subarctic regions. Our study area is the Rosa-Keystone Du…

AMS Dating of the Late Pleistocene Mammals at the Colorado Creek Site, Interior Western Alaska
The Colorado Creek section of Alaska is an important paleontological site first excavated and reported on in the early 1980s and 1990s. The remains of two individual mammoths (the “Upper” and “Lower”), and elements of horse, bison, and caribou make this a unique faunal assemblage for a region in interior western Alaska, and the western edge of eastern Beringia. The mammoth remains were the only portions of the faunal assemblage radiocarbon dated …

Rediscovering lost relationships
In 1931, the Hudson's Bay Company cargo steamer, SS Baychimo , was trapped in sea ice and abandoned in the Chukchi Sea off the northern coast of Alaska. Large amounts of scientific and navigational instruments and gear and personal items were left aboard, among them an ethnographic collection gathered in 1930 from Inuit groups in the Canadian Arctic by Richard Sterling Finnie. The ship was boarded several times over the next three years with item…
