1981 Map of Poker Brown Spring

USGS Topo · Published 1982

About this map

The high desert terrain of Pershing County is defined by the Trinity Range in this 1981 survey, where relief is carved by numerous drainages including Poker Brown Canyon and South Trinity Canyon. Water sources are few and vital in this arid landscape, centered on Poker Brown Spring and Trinity Spring. The map reflects an environment focused on resource extraction and industrial infrastructure rather than permanent settlement. Scattered evidence of mining activity appears through labels for a Mine and several Prospect sites, while the presence of a Pipeline and 4WD tracks suggest the modern management of this remote territory. For researchers, the map provides a precise record of the physical landscape and access routes used by the mineral industry in the late twentieth century.
