The Elephant Canyon Formation is the basal Permian geologic formation of the Cutler Group overlying an unconformity on the Pennsylvanian Honaker Trail Formation in the Paradox Basin of southern Utah.[1][2]
Description
It consists of pink dolomite, light-gray dolomitic sandstone, light-brown and moderate-red, fine-grained sandstone, a basal conglomerate and conglomeratic sandstone, and limestone. The basal conglomerate is composed of moderately sorted cherts up to 3 cm in diameter. It weathers to a medium brown and forms hackly, blocky ledges and intervening slopes.[3]
