Two volunteers from the hatchery strolled by our camping spot the other night and we chatted for an hour. They told us about this place. It’s located just off Interstate 90 as you enter Wyoming ( near Beulah). It doesn’t look like much at first but it’s a fascinating history lesson. We took the guided tour though the museum and down into the sink hole that several tribes used to run bison to their deaths. They could harvest enough meat and bones and marrow to last the tribe for a long time. The meat could be dried into jerky or ground up and mixed with choke cherries and marrow fat to make Pemmican. It’s sort of like a meaty trail bar. Jackie was a well informed and interesting guide. She patiently answered our many questions and took her time as we made our way back up that steep and long path from the pit. The site was discovered by workers checking the stability of the sink hole when the interstate was being constructed. They performed a core sample and pulled up bison bones. Fascinating find.
