About this map

The Palo Verde Mountains and Mule Mountains dominate this arid landscape in the mid-1950s, defining a region of stark volcanic landforms and historical desert corridors. The map records a series of prominent summits including Palo Verde Peak and Thumb Peak, alongside the unusual Flat Tops and the Geode Beds, which indicate the geological character of this corner of Imperial and Riverside counties.

Evidence of early desert transit is preserved in the route of the Butterfield Stage Line and the Niland Rannels Road, which navigate through the rugged terrain alongside Milpitas Wash. The presence of several prospects and localized water sources like Clapp Spring and Coon Hollow highlights the precarious nature of settlement and industry in the Colorado Desert during this era. A southern Naval Reservation and numerous jeep trails further underscore the mid-century's military and exploration footprints in the California backcountry.
