At leas t three sequential bison kills that seemingly occurred in late fall ar e contained in the deeply buried deposits. This eastern Plains periphe ry site's similar corner notched dart points, identical geomorphic set ting of all bone deposits, and radiocarbon assays suggest site use dur ing the Late Archaic/Woodland transition, ca.
