About this map

The Black Mountains dominate the western portion of this mid-century survey, dropping sharply into the wide expanse of the Sacramento Valley. This arid landscape is defined by its scarce water sources, including Cave Spring and Trough Spring, which likely served as vital landmarks for early travelers and cattlemen. The terrain is bisected by the notable Secret Pass and its associated Secret Pass Canyon, a natural corridor through the range.

Evidence of local industry and infrastructure appears in the form of a Mine located near the canyon and a Gravel Pit to the north. Transportation across the valley floor is limited to Estrella Road and various jeep trails, while a long-distance telephone line follows the natural contours of the valley. The drainage patterns are clearly marked by the Sacramento Wash and Secret Wash, illustrating the seasonal water flow that shapes this desert environment.
