1985 Map of Desert

USGS Topo · Published 1985

About this map

Von Schmidt Boundary (1873) cuts across this desert landscape, marking the historic line between Nevada and California. The rugged eastern portion is dominated by the Lucy Gray Mountains, where the Lucy Gray Mine stands as a focal point of industrial activity. To the west, the arid expanse of the Ivanpah Valley and the dry bed of Ivanpah Lake define the terrain. The Union Pacific railroad runs through the valley, serving the small settlement of Calada. This map also preserves precise historical markers such as the 3 1/2 Mile Mon State Mon 126, which anchors the 19th-century survey lines through this high-desert region of Clark and San Bernardino counties.
