2021 Map of Lead Mountain SW

About this map

The Bullion Mountains dominate the northern terrain of this 2021 study, rising sharply above the arid floor of the Mojave Desert. This particular expanse of the high desert is defined by the passage through Cleghorn Pass, a natural gateway between the ridgelines that has long influenced movement across this part of San Bernardino County. The landscape is marked by the grid of the Public Land Survey System, with township and range lines like t3n r10e and t2n r10e providing the primary human structure over an otherwise unpopulated mountain wilderness. The map captures the stark topography of the area just as it appeared in the early 2020s, showing the intricate contouring of the slopes and the dry wash networks that characterize the desert interior.
