1990 Map of Coyote Peak

About this map

The Little Horn Mountains dominate this arid landscape on the border of La Paz and Yuma Counties. This 1990 provisional survey documents a transition zone where the Ranegras Plain meets the high peaks of the Kofa National Wildlife Refuge. The map captures a quiet interior of the Sonoran Desert, defined by seasonal water management and rugged landforms. Scattered prospects and a Mine Shaft indicate a history of mineral exploration, while several Check Dams and the Vinegaroon Well highlight the infrastructure required for life and livestock in this environment. Significant landmarks like Coyote Peak, the Royal Arch, and Natural Arch serve as permanent beacons across the vast terrain. Modern access is represented by Hovatter Road and various 4WD trails that navigate the washes, including Cementosa Wash.
