2012 Map of Lead Mountain SW

About this map

Bullion Mountains dominate the northeastern portion of this arid California landscape, providing a rugged backdrop to the expansive military and transit infrastructure in the high desert. The terrain is defined by the natural corridor of Cleghorn Pass, a significant topographical break in the mountain range that has historically influenced movement through this part of San Bernardino County. This 2012 survey illustrates the modern footprint of the 29 Palms MCAG, showing how military boundaries intersect with the sparse local road network. The presence of Steeg Rd serves as a primary artery through the desert floor, tracing a path that connects these remote geological features with the broader regional infrastructure. The map clearly delineates the sharp contrast between the untouched mountain peaks and the structured zones of the Marine Corps Air Ground Combat Center.
