1987 Map of Hanging Rock Canyon

USGS Topo · Published 1987

About this map

Last Chance Range dominates this mid-1980s landscape, where steep topography transitions sharply into the broad expanse of Eureka Valley. The map reveals an area defined by mineral exploration and high-desert infrastructure, characterized by numerous prospects and open pit mines scattered across the ridgelines. Of particular interest to historians is Crater (Site), appearing as a named location tucked within the range near several extraction points. The network of 4wd tracks provides the only access through Hanging Rock Canyon, illustrating the isolation of these industrial sites. In addition to mining for materials like lead, the map identifies several vertical flight data targets, such as Vfdt 9-258, indicating the region’s use for aerial survey and geodetic control in the latter half of the 20th century.
