| Description |
The Beaverhead Rock area is located north of Dillon, Montana, and includes Tertiary deposits on the eastern flank of McCartney Mountain as well as basement rocks of the Selway terrane. Strata show evidence of deformation during the Paleoproterozoic Big Sky orogeny, Cretaceous through Paleogene Sevier-Laramide orogeny, and Miocene to present Basin and Range extension. Past exploration activities have shown minimal potential for mineral or petroleum resources.
