1933 Map of Dome Rock Mts

About this map

The Colorado River Indian Reservation dominates the western portion of this 1933 survey, stretching from the banks of the Colorado River into the heart of the arid interior. The landscape is defined by the sharp elevations of the Dome Rock Mountains, which historically served as a significant site for mineral extraction. Numerous mining operations are mapped here, including the Goodman Mine, Cinnabar Mine, and the Copper Chief Mine, suggesting an era when prospectors and companies heavily exploited the area for gold, copper, and mercury. Water sources like Tule Springs and the Beamer Well provide essential landmarks in an environment otherwise shaped by dry washes such as Goodman Wash and Ehrenberg Wash. Transportation patterns are evidenced by the Old Arroyo Road, which navigates the complex terrain of the Copper Bottom Pass and Marquetta Pass, linking isolated mine sites to the river valley.
