This week we interview Dr. Spencer Pelton, the Wyoming State Archaeologist, about his work on the Powers II red ochre quarry site. He recently co-authored a paper about that site, and in it they reveal that the dating results make the Powers Site potentially the oldest quarry site in North America. It's a fascinating and unique site and Dr. Pelton graciously shares his expertise on red ochre, how it was mined, and how it was potentially used by Paleoindian people in Wyoming.
