Ground-penetrating radar (GPR) offers many advantages for assessing archaeological potential in frozen and partially frozen contexts in high latitude and alpine regions. These settings pose several challenges for GPR, including extreme velocity changes at the interface of frozen and active layers, cryogenic patterns resulting in anomalies that can easily be mistaken for cultural features, and the difficulty in accessing sites and deploying equipment in remote settings. In this study we discuss some of these challenges while highlighting the potential for this method by describing recent successful investigations with GPR in the region. We draw on cases from Bering Land Bridge National Preserve, Cape Krusenstern...

The Archaic stage was defined as a cultural response to post-Pleistocene landscapes dominated by trees. The Early Holocene produced an open landscape susceptible to colluviation, flooding, and gullying thus placing severe constraints on archaeological site preservation. The paleo-environment surrounding the development of the Northern Archaic can be reconstructed from pan-Alaska proxy records of flooding, loess fall, and soil formation at Onion Portage and Tingmiukpuk, and using a variety of studies of lake levels, glacial expansions, and slope activations, supplemented by loess and dune stratigraphy from the Tanana and Nenana valleys. The development of the Northern Archaic correlates with the retreat of the treeline,...
