The Fenn Cache: Artifact #151

No one knows what this crescent-shaped tool was used for, though it has turned up in association with Clovis points elsewhere. While the tool's middle edges are dull from grinding, its ends remain sharp. It is made of chert from the Green River Formation of southwestern Wyoming and contiguous parts of Utah and Colorado. This is not far from where the cache is believed to have been found, the three corners area where Utah, Wyoming, and Idaho come together.
