About this map

The Yuma Proving Ground dominates this mid-1980s landscape, illustrating the restricted military presence that has shaped this portion of the Arizona desert. The terrain is defined by the Dome Rock Mountains and the South Trigo Peaks, where natural corridors like Trigo Pass, Weaver Pass, and Felipe Pass provide the only practical routes through the sharp relief.
