1982 Map of Iron Ridge

USGS Topo · Published 1993

About this map

The Rodman Mountains define the northern reaches of this high desert terrain, where the landscape is marked by the distinct industrial and military activities of the early 1980s. Resource extraction is a central theme, evidenced by the Bessemer Mine and several Prospects, along with an Open Pit Mine and associated Mine Dump. These features suggest a period of intense geological investigation and mineral pursuit in the Upper Johnson Valley.
