1987 Map of Oasis Divide

USGS Topo · Published 1987

About this map

The Silver Peak Range dominates this landscape in Esmeralda County, revealing an arid expanse defined by high-altitude mining activity. The 1987 survey identifies several industrial sites, including the Heavy Rock Mine in the northern ridges and extensive Open Pit Mines further south. A significant historical marker, the Von Schmidt Line (1873), cuts across the southwestern corner, referencing the original 19th-century boundary survey between California and Nevada. High desert terrain is further marked by the geographic Oasis Divide, where transmission lines and unimproved roads navigate between peaks and through White Wolf Canyon. The map provides a clear record of the area's geological extraction and the persistence of early territorial boundaries.
