1990 Map of Slumgullion Pass

USGS Topo · Published 1990

About this map

The Castle Dome Mountains dominate this arid landscape within the Kofa National Wildlife Refuge in Yuma County. This provisional 1990 survey, based on data collected across several decades, reveals a high concentration of mineral exploration and water management in a desert environment. Prospectors and miners were active at the Big Eye Mine and the Keystone Mine, while several unnamed Mine Shaft and Prospects labels indicate widespread extraction efforts.
