1967 Map of Secret Pass

About this map

The Black Mountains dominate the western portion of this mid-century desert survey, where steep terrain gives way to the broad Sacramento Valley in the east. Central to the landscape is Secret Pass, a natural gateway through the range that connects to Secret Pass Canyon and Sacramento Wash. The availability of water in this arid environment is clearly documented by the presence of Cave Spring, Trough Spring, and another unnamed Spring, suggesting the historic importance of these locations for both travel and cattle.
