Chugwater Formation

The Chugwater Formation is a mapped bedrock unit consisting primarily of red sandstone, in the states of Wyoming, Montana, and Colorado in the United States. It is recognized as a geologic formation in Colorado and Montana, but as a Group (set of formations), the Chugwater Group, in Wyoming. Despite its presence below the highly studied Morrison Formation, the Chugwater receives little attention.
