Summary

A finely made bifacial skinning knife was left on a small natural pointed hill apparently as a non-utilitarian offering placed on a high promontory, a common prehistoric practice across much of western North America. Age is unknown, but the tool is believed to date from the Late Prehistoric Period or terminal Archaic, or about A.D. 200-1200.
