The Bullion Mountains dominate this high-desert landscape in San Bernardino County, where the topography is defined by sharp contour lines and arid peaks. This mid-century survey by the Geological Survey and the California Department of Water Resources records a transition in land use, as indicated by the presence of a Training Center designation across the central and southern portions of the sheet. The map is a study in verticality and military geography, centered on the high ground of Vabm Rough. With few roads or permanent civilian structures, the area serves as a primary example of the mid-20th-century desert ranges that were repurposed for strategic defense and training purposes, leaving much of the natural terrain undisturbed save for survey markers.
