Moses Coulee dominates this mid-1960s landscape at the boundary of Douglas and Grant Counties, revealing a dramatic geomorphology shaped by ancient floods. The quadrangle is marked by a network of steep canyons and water sources, including Rattlesnake Springs, Mineral Spring, and Bell Spring, which historically supported life in this arid region. The presence of Three Devils Grade indicates the challenging engineering required to traverse the elevation changes between the coulee floor and the surrounding plateaus.
