About this map

Malapai Hill stands as a prominent topographical marker in this arid landscape of Riverside County, where water resources are defined by ephemeral drainage systems like Fried Liver Wash. The 2012 geography is characterized by essential backcountry water points such as Pinyon Well and various rock-basin catchments including Live Oak Tank, Ivanpah Tank, and Twin Tanks. These features were critical for early transit and remain vital landmarks in the desert environment.

Road access is provided by Park Blvd and Pinto Basin Rd, which connect several key recreational sites. Significant geologic formations like Skull Rock and the massive boulders of Jumbo Rocks draw visitors to established locations like the Jumbo Rocks Campground, White Tank Campground, and Sheep Pass Group Campground. This survey documents a wilderness area where geologic landmarks and seasonal water sources dictate the patterns of human activity and exploration.
