The Archaeology of Beringia by Frederick H. West
Twelve thousand years ago a climatic warming trend submerged the remains of the land bridge between Siberia and Alaska. The indigenous population of the vast plain that linked Siberia to Alaska was forced to emigrate to the east. Long considered merely a passageway, Beringia, in Frederick Hadleigh West's view, is better understood as a complete biotic province unto itself, home for early peoples, and an important center of dispersion for many species. The Archaeology of Beringia is West's painstaking synthesis of all recent findings on the inland hunters of Beringia and their unique arctic culture.
