Abstract

Shell Valley, from the mouth of Shell Canyon, to its junction with the Bighorn Hiver in east-central Bighorn County, Wyoming, was mapped and the fluvial landforms were described in detail. The morphologic features of this valley and its major tributaries are largely the product of structurally-controlled stream erosion and alluviation. Their disposition indicates that they have been produced by lateral planation, slope retreat, simple downcutting, and downcutting accompanied by lateral migration of the stream, all of which are still active. Correlation of the local features with some more regional features, which have been dated, indicates that much of the Erosional history of Shell Valley was confined to the Pleistocene.
