About this map

The Yuma Proving Ground dominates this arid landscape in Yuma County, characterized by the stark intersection of military testing infrastructure and raw desert terrain. The northeastern portion of the quadrangle is defined by the expansive Castle Dome Plain, while the southern reaches are crowded by the complex ridges of the Muggins Mountains and Red Bluff Mountain. This area serves as a significant site for high-altitude observation and defense testing, noted by several Observation Tower locations and numerous scattered Prospect labels that hint at historical mineral exploration in the canyons.
