When I am prospecting for Eocene fossils in Wyoming, I often come upon archeological remains such as this artifact. The Bridger Formation is the source of countless tons of chert that can be made into stone tools. The native peoples of this region would seek out good examples of useful stone.
I see millions of stone flakes "lithics" out in the badlands. Complete stone tools are rare. This is in part due to the looting of archeological resources by amateur "pothunters" and dealers in illegaly obtained antiquities. I left this bifacial quartzite artifact where I found it as it is a Fedeal crime to collect antiquities on BLM admistered lands without a permit. My permit is for the surface collection of vertebrate fossils.
