About this map

Mining operations and remote desert outposts define this 1956 mid-century survey of the high Mojave landscape. The Union Pacific railroad corridor serves as the industrial spine of the region, connecting small stations like Nipton, Moore, and Brant. Further east, the historical weight of the Von Schmidt Line (Approx) (1873) marks the enduring boundary between California and Nevada.

Mineral extraction is the primary human imprint across the Ivanpah Mountains and the New York Mountains. Significant sites such as the Carbonate King Mine, Morning Star Mine, and Sagamore Mine are documented alongside numerous shafts and prospects. These workings, clustered around landmarks like Kokoweef Peak and Mineral Hill, reflect the rugged economic life of San Bernardino County before modern development transformed the region.
