EaOp-6, Saamis: This late prehistoric site consists of five areas designated A-E. Area B represents campsite activities with a number of basin hearths containing layers of fired rock. Area C is primarily a meat processing area, and Area E is thought to represent butchering and possibly meat processing and killing of bison. S-824 and S-827 are well within the expected time range, and they correspond to their stratigraphic positions. However, S-825 is too late, since stratigraphically and culturally it should fall in the same time period as S-824. [Note that the normalized age overlaps the estimate at 2-sigma.]
