About this map

Pine Creek Tungsten Mill and several high-altitude mining operations define the industrial character of this high Sierra landscape. Set within the overlapping boundaries of the John Muir Wilderness, Inyo National Forest, and Sierra National Forest, the map traces a complex network of extraction sites like the Tungstar Mine, Lambert Mine, and the Brownstone Mine. These operations were supported by specialized infrastructure, including a tramway and aqueduct, facilitating resource movement through difficult terrain near Four Gables and Mount Tom.

The western portion of the sheet opens into Humphreys Basin and French Canyon, a lake-rich region featuring Steelhead Lake, French Lake, and Puppet Lake. This 1982 survey illustrates the transition from heavy mineral extraction to protected wilderness, where old ruins and a corral sit near alpine passes like Pine Creek Pass. The map serves as a detailed record of the mining era's footprint on the Inyo and Fresno county line.
