About this map

Dome Rock Mountains and the surrounding high desert terrain define this southwestern Arizona landscape during the early 1970s. The region is marked by significant mineral extraction history, evidenced by a cluster of named workings such as the Copper Bottom Mine, Yellow Dog Mine, and Cinnabar Mine. These sites are linked by rugged jeep trails and passes, including Copper Bottom Pass and Weaver Pass, which navigate the steep elevations between Sawtooth Mountain and Cunningham Mtn.

A notable boundary for the Yuma Proving Ground occupies the southern portion of the sheet, while an Indian Reservation Boundary cuts across the northwestern corner. Evidence of long-standing human presence in the arid environment is found at Petroglyphs near Tule Springs, contrasting with modern infrastructure like the prominent Pipeline and the Airway Beacon that facilitate transit across the La Posa Plain.
