is found deep in La Sal Creek Canyon where a disseminated ore body formed adjacent to a small normal fault. Following discovery in 1897, the Cashin Mine operated here from 1899 to sometime in the 1950s producing both copper and silver.
Copper mineral staining is common on exposures of sandstones around the mine site.
