About this map

The Yuma Proving Ground dominates this arid landscape in the mid-1980s, defined by its Military Reservation Boundary and the stark topography of the Trigo Mountains. This area is characterized by an extensive network of desert drainages, including Trigo Wash, Weaver Wash, and Mohave Wash, which carve through the high terrain of the North Trigo Peaks and South Trigo Peaks.
