Late Pleistocene Settlement in the Nenana Valley, Central Alaska

Ongoing research in the Nenana Valley is uncovering a complex record of Late Glacial settlement in the foothills of the Alaska Range. A local eolian sequence provides relatively precise stratigraphic and chronological control, permitting integration with regional paleoclimatic history. Initial occupation seems to have occurred approximately 12,000 years ago, and is represented by several assemblages containing bifacial points. Microblade technology did not appear until ca. 10,500 B.P. The valley probably was exploited on a seasonal basis for large mammal procurement.
