Mule Mountains and the McCoy Mountains dominate this arid landscape in the southeastern Colorado Desert, flanking the wide alluvial expanse of the Chuckwalla Valley. This 2015 survey details a rugged section of Riverside County where the land rises sharply toward the Palo Verde Mesa. Human activity here is defined by long-distance transit and historical desert routes, centered on the corridor of Interstate 10 which cuts through the northern half of the map. Traces of older desert passage are evident in the Bradshaw Trl at the southern edge, a historic path through the desert mountains. The map also documents access points such as McCoy Springs Rd and Blackrock Rd, which serve the isolated high ground near Black Rock.
