1970 Map of Whipple Wash

About this map

The Whipple Mountains dominate this California landscape, where complex geological formations and deep desert drainages define the area north of the Colorado River. Notable for its industrial and mining footprint during the early 1970s, the map identifies the Colorado River Aqueduct Tunnel traversing the southern portion of the range, an essential piece of regional water infrastructure. Mining activity is evident through the presence of the Islander Mine, the Whipple Mtn Adit, and various unnamed mines and prospects scattered across the high ground. The eastern section of the quadrangle includes the Colorado River Indian Reservation Boundary, marking the edge of tribal lands. Major natural features like Copper Basin and the prominent Monument Peak anchor the topography, while a network of jeep trails and the Copper Basin Trail provide the primary means of navigating this arid terrain.
