Prior to Middle Awash I asked to examine With cultural remains dated unequivocally to 13,000 calendar years ago, Dry Creek assumed major importance upon its excavation and study by W. Roger Powers. The site was the first to conclusively demonstrate a human presence that could be dated to the same time as the Bering Land Bridge. As Powers and his team studied the site, their work verified initial expectations. Unfortunately, the research was never fully published.Dry Creek: The Archaeology and Paleoecology of a Late Pleistocene Alaskan Hunting Camp is ready to take its rightful place in the ongoing research into the peopling of the Americas. Containing the original research, this book also updates and reconsiders Dry Creek in light of more recent discoveries and analysis. ABSTRACT. Joe . D. . Dragovich. 1. , . James H. .
