Holocene prehistory of the northernmost north Pacific

We examine evidence for Holocene contact between Asia and North America across what is now the Bering Strait, emphasizing maritime adaptation. After 10,000 B.P. residual influence of the Siberian Paleolithic is clear, and derivative Americans were moving southward along the open Pacific coast and settling in the eastern Aleutian Islands. By 6000 B.P. maritime adaptation is evident in the Kodiak Island region, and expansion westward brought colonization of the entire Aleutian chain of islands before 3000 B.P. In Asia there was marine subsistence on Hokkaido by 6000 B.P, but in the lower Amur River region, the southern and northern regions of the Okhotsk Sea, the coast of Kamchatka, and the Chukchi Peninsula no major maritime interest can be dated until after 2700 or even 2500 B.P In north Alaska, the mainland was cut off from Siberia by 6000 B.P with the rise of postglacial seas, but contact was reestablished 5000 B.P at the cultural level of the nonmaritime Siberian Neolithic. Pronounced marine orientation appears intrusively in north Alaska somewhat before 3000 B.P, when the only known source for the technology was the region extending from the Gulf of Alaska through the Aleutian Islands. Thereafter developed the maritime culture of the historic Eskimo people.
