About this map

The Trigo Mountains dominate this arid landscape in La Paz County, where the high point of Mohave Peak overlooks a network of desert drainage systems. This 1986 survey documents a significant portion of the Yuma Proving Ground, illustrating the intersection of military land use and the natural topography of the Sonoran Desert. The map reveals the intricate patterns of seasonal waterflow through features like Mohave Wash, Gould Wash, and Yuma Wash, which cut across the high-relief terrain.

Evidence of historical resource exploration is scattered throughout the mountains, marked by various Prospect and Prospects sites. These labels indicate a history of mineral interest in the area, likely predating the formalization of the military reservation. The geography here is defined by these isolated mining attempts and the vast, undeveloped stretches of the Mc Allister Wash corridor, providing a clear record of this specialized desert environment during the mid-1980s.
