These conditions prevail to a point within half a mile of the mouth of the valley, where the stream enters a rock canyon, with nearly vertical walls, that extends to its mouth. Throughout the basin of Crow Creek, the bedrock consists predominantly of interbedded argillites or shales and graywackes, with some conglomerates, cut by numerous granitic dikes and sills. Locally, the shale beds have been metamorphosed, with the development of slaty cleavage, and in places the metamorphism has been intense enough to produce a somewhat schistose structure.
