On Your Knees Cave

On Your Knees Cave is a terminal Pleistocene archaeological site on Prince of Wales Island in the Alexander Archipelago. Discovered in 1993 and excavated in the mid-1990s, the site yielded ancient human remains and an assemblage of faunal and cultural materials that have informed debates about early human migration into the Americas, Paleoindian occupation models, and paleoenvironments of the late Pleistocene and early Holocene.

Discovery and Excavation

The cave was found by a local Alaska Native and subsequently reported to regional heritage authorities, prompting investigations by teams from the University of Alaska Fairbanks, the National Park Service, and the Smithsonian Institution. Field seasons in 1996 and 1997 involved systematic stratigraphic excavation, sediment sampling, and documentation using methods adopted from projects at Hoyo Negro, Monte Verde, Topper Site, Clovis-era localities, and coastal assessments like those at L'Anse aux Meadows and Channel Islands National Park. Excavators applied radiocarbon dating protocols established by laboratories involved with Woods Hole Oceanographic Institution-associated projects and comparanda from Kennewick Man and Spirit Cave research. Coordination included compliance with Native American Graves Protection and Repatriation Act processes and consultation with Tlingit and other regional Indigenous communities.

Human Remains and Archaeological Findings

Excavations produced a partially articulated human skeleton, curated and studied by physical anthropologists including Douglas W. Owsley and teams associated with the Smithsonian Institution's National Museum of Natural History. Direct radiocarbon dating of collagen placed the remains in the late Pleistocene, contemporaneous with dates reported from Manis and some estimates for Bluefish Caves. The assemblage included microliths and worked bone, comparable to artifacts from coastal route localities and suggested subsistence strategies akin to those inferred at Paisley Caves, Marmes Rockshelter, and Channel Islands sites. Faunal remains of marine and terrestrial species linked the deposit to ecological contexts similar to those reconstructed at Yukon River and Bering Land Bridge National Preserve sites. Morphological analysis contributed to comparative studies involving Kennewick Man, Naia, and other early American individuals, informing discussions that connect to research by institutions such as the American Association of Physical Anthropologists.

Geological and Paleoclimatic Context

Sediments in the cave preserve a stratigraphy reflecting late Quaternary sea level changes and postglacial vegetational shifts documented in palynological and sedimentary studies similar to work at Seward Peninsula, Prince Rupert, and Haida Gwaii. Geomorphologists linked deposit sequences to regional deglaciation chronologies derived from studies in the Cordilleran Ice Sheet margin, Fairbanks-area cores, and isotopic work used in Greenland ice core comparisons. Marine transgression and regression phases mirrored patterns reconstructed for the Beringia corridor and coastal refugia invoked by proponents of the kelp highway hypothesis and coastal migration models championed in comparative analyses with Monte Verde and Southeast Alaska paleoecology research. Paleoclimatic proxies from the site align with millennial-scale events discussed in literature on the Younger Dryas and early Holocene warming episodes.

Cultural and Scientific Significance

The site's antiquity and context have had wide resonance across debates concerning the timing and routes of early human colonization of the Americas, intersecting with work by researchers associated with University of Alaska Anchorage, University of Washington, University of California, Santa Barbara, and the University of Oregon. Findings informed policy and ethical dialogues involving the National Park Service, the Smithsonian Institution, and Indigenous stakeholders, paralleling controversies seen in the study of Kennewick Man and repatriation cases under the Native American Graves Protection and Repatriation Act. On the scientific front, the remains contributed to morphological, genetic, and isotopic comparisons with Ancient North Eurasian models, Beringian Standstill hypotheses, and coastal dispersal frameworks advanced by interdisciplinary teams including archaeologists, geneticists at institutions like the Max Planck Institute for Evolutionary Anthropology, and paleoecologists at the National Oceanic and Atmospheric Administration. The site is frequently cited in syntheses by the Society for American Archaeology and in reviews addressing late Pleistocene human adaptations across North America.

Conservation and Access

Responsibility for stewardship involves collaboration among local tribal authorities, state agencies such as the Alaska State Museum and the Alaska Office of History and Archaeology, federal entities including the National Park Service, and research institutions that conducted the original excavations. Access to the cave and associated collections is managed under protocols similar to those applied to other sensitive sites like Mound 72 and Windover Archaeological Site, balancing research, curation at institutions such as the Smithsonian Institution, and Indigenous rights under NAGPRA. Ongoing conservation measures address site stabilization, climate impacts parallel to concerns at Glacier Bay National Park and Preserve, and curated storage standards practiced by university and museum facilities.
