About this map

Mining operations and high Sierra terrain dominate this 1970s survey of the California-Nevada borderlands. The industrial impact is most visible at the Leviathan Mine and the nearby Leviathan Mine Ruins, where Tailings are clearly marked along the drainage of Leviathan Creek. Further south, the map documents a cluster of historical workings including the Zaca Mine, Globe Mine, and Red Gap Mine situated near the Monitor Creek drainage, illustrating the intensity of mineral exploration in this corner of the Toiyabe National Forest.

Water management and geography define the lower elevations, notably at Heenan Lake with its marked Spillway and the winding course of the East Fork Carson River. The map also preserves the 1873 California-Nevada State Boundary and the Von Schmidt Line, providing critical context for researchers of state line disputes. Named flats like Centerville Flat and Forest City Flat offer specific points of interest for local historians tracking early settlement patterns and livestock grazing areas in the Sierra Nevada.
