About this map

Brawley Peaks dominate the northwest corner of this landscape, marking a rugged high-altitude transition toward the shores of Mono Lake to the south. The 1950s terrain reveals a legacy of resource extraction and frontier transit, with the Old Railroad Grade and numerous tracks like Pole Line Road cutting through Mono Valley and Alkali Valley. Historic industrial and settlement sites are scattered throughout, including the Syndicate Mill (Site), Gray Mill, and the Toll House located near the northern springs.

Water is the defining lifeblood of this arid district, indicated by concentrated clusters of seasonal and permanent sources. Significant hydrology includes Walford Springs, the remote Larkin Lake, and Warm Springs along the lake's northeastern edge. Of particular interest to local historians is the Mark Twain Camp in the Toiyabe National Forest, providing a physical link to the region's literary and mining lore along the border of Mineral Co and Mono Co.
