About this map

The Dome Rock Mountains dominate this 1970s landscape, serving as a hub for mining activity and desert travel. The map documents several named mineral operations including the Marquitta Mine, Dome Basin Mine, and Colrio Mine, with extensive Tailings and Prospects scattered through the high ground. To the west, the Colorado River Indian Reservation boundary runs north-to-south, separating the high peaks from the lower drainages.

Surface water is a defining challenge of the era, evidenced by the scattered network of dry washes and man-made improvements. Key water features like Oldman Tanque and Lead Well provided critical points of interest for travelers and livestock alike. Low-lying areas such as the La Posa Plain are bisected by significant drainages like Tyson Wash and La Cholla Wash, while the small settlement of Gonzales sits near the Dome Rock Interchange, reflecting the intersection of modern transport and the older mining landscape.
