1982 Map of Hidden Valley West

About this map

The Cady Mountains dominate this high-desert landscape in San Bernardino County, where drainage patterns define the arid environment. Along the northwestern edge, the Mojave River is a primary landmark, featuring the Ninemile Waterhole, an essential water source in an otherwise parched corridor. The terrain is marked by seasonal drainages like Wilhelm Wash that cut through the elevation toward the southeastern expanse of Hidden Valley. Evidence of small-scale mineral exploration is present throughout the hills, indicated by various Prospects scattered among the peaks and washes. This 1980s-era survey represents the desert just before significant modern shifts in land management, showing a territory primarily shaped by natural topography and the search for minerals.
