The WSA is part of the Kaiparowits Plateau, in the Canyonlands Section of the Colorado Plateau Physiographic Province. The surface of the WSA slopes generally northward, and consists of benches and south facing cliffs. Some specific locations in the WSA provide exceptional scenic geologic features. The East Kaibab monocline, or The Cockscomb, extends along the western boundary of the WSA. The monocline contains a feature known as Cads Crotch which is a trough on the crest of the structure.
