The WSA is dominated by Mt. Ellsworth and Mt. Holmes, two mountain peaks which are bodies of igneous rocks that intruded and deformed overlying sedimentary layers. In the northern and eastern portions of the area there are high, narrow mesas cut by deep canyons. Almost half the WSA is bare rock outcrop. Blackbrush and other shrubs are the dominant vegetative type in the remainder of the area.
