1971 Map of Dome Rock Mts SW

About this map

The Dome Rock Mountains dominate this 1970s landscape, defined by a complex network of desert drainages and mid-century resource extraction. At the base of the peaks, the Copper Giant Mine and Copper Chief Mine illustrate the region's mineral history, while numerous unnamed Prospects and Mines dot the arid slopes. The terrain is deeply incised by several major washes, including Ehrenberg Wash, Limekiln Wash, and La Paz Arroyo, which flow toward the Colorado River valley located just beyond the western margin. Significant administrative divisions shape the land use here, specifically the northern reach of the Yuma Proving Ground and the historical Old Indian Reservation Boundary. Evidence of modern infrastructure appears via the Pipeline corridors and the presence of a Rest Area in the northern corridor, providing a glimpse into the industrial and military utility of this desert expanse during the early 1970s.
