About this map

The high desert landscape of Ivanpah Valley and the northern reaches of the New York Mountains define this region in the early 1980s. The settlement of Ivanpah sits at a crossroads of the modern Union Pacific Railroad and an older era of transport, marked clearly by the Old Railroad Grade that cuts across the valley floor. This transition between the flat expanse and the rising slopes reveals a history deeply tied to mining and reliable water sources in an arid environment.

Mining activity is concentrated in the steep canyons of the south, where operations like the Sagamore Mine and Giant Ledge Mine are situated near vital springs. Several named water sources, including Slaughterhouse Spring and Keystone Spring, provided the necessary infrastructure for these remote sites. Farther west, the siding at Brant served as a key point along the rail line, while family-named landmarks like Lecyr Well and Mail Spring point to the grazing and prospecting history of San Bernardino County.
