About this map

Mining operations and narrow desert corridors define this landscape in the early 1970s. The Dome Rock Mountains dominate the terrain, carved by a network of drainage systems including Tyson Wash and Gonzales Wash. Local prospecting is evident through several named sites such as the Dozier Basin Mine and the Colrio Mine, while evidence of heavy industry remains visible at the Tailings south of Middle Camp Mtn.

Navigating these elevations required the use of specific natural breaks like Boyer Gap, Marquitta Pass, and Diablo Pass. The western edge of the map is delineated by the Colorado River Indian Reservation Boundary, marking a clear administrative division in the desert. To the east, the terrain levels out into the La Posa Plain, where the Oldman Tanque provides a rare reference point in the arid flats.
