Bullion Mountains dominate this arid landscape within the Mojave Desert, where the elevation contours reveal a series of dry basins and steep ridges. The map identifies the Cleghorn Lakes, which appear as ephemeral catchments typical of this high desert environment in San Bernardino County. Surveyed for the Public Land Survey System, the area is divided into several townships including t3n r11e and t2n r12e. This topographic record provides a detailed look at the unpopulated desert interior, focusing on the natural drainages and landforms of the mountains before they descend into the broader desert floor. The lack of roads or established structures highlights the isolation of this corner of the California desert.
