1990 Map of Plomosa Pass

USGS Topo · Published 1990

About this map

The Plomosa Mountains dominate this landscape of the Sonoran Desert, defined by a complex network of ephemeral drainage systems and mining claims. Arid water features like Lazarus Tanks and the winding Italian Wash provided critical points of reference in a terrain where extraction was the primary driver of human activity. The map reveals an intensive history of prospecting, with numerous shafts and adits concentrated near Guadalupe Mountain and Scaddan Mountain.
