1951 Map of Blanco Mountain

USGS Topo · Published 1958

About this map

Roberts Ridge and the surrounding high-altitude terrain of the Inyo National Forest dominate this mid-century survey, revealing a landscape defined by isolation and mineral exploration. The presence of the Naval Research Station near Sage Hen Flat and the Radio Relay Sta atop the peaks suggests the region's importance for specialized scientific and communications infrastructure during the 1950s. Mining activity is scattered throughout the canyons, with the Wilkerson Mine, Mollie Gibson Mines, and Grandview Mine marking the efforts to extract wealth from these mountains.
