1955 Map of Cleghorn Lakes

About this map

The Bullion Mountains dominate this high-desert terrain of San Bernardino County, where the landscape is defined by vast volcanic and metamorphic ridges and arid basins. In the mid-1950s, this area was established as a critical military training zone, largely encompassed by the Marine Corps Training Center. The presence of a Dry Well and the ephemeral Cleghorn Lakes highlights the extreme conditions of the region, where water sources were scarce and vital for any operation. Mapping points like Bullion East VABM 4046 and Bald VABM 4079 served as essential survey benchmarks in this wide-open environment. A solitary Jeep Trail provides the primary ground access through the foothills, indicating the limited development and specialized use of the land during this period.
