About this map

Big Potrero Valley dominates this 1960s-era survey of the southern California borderlands, where the small community of Potrero serves as a hub for local ranching and transit. The landscape is defined by the international boundary between the United States and Mexico, with the San Diego and Arizona Eastern RR following the winding terrain near the border. Along the valley floor, Potrero Creek and the small Picnic Lake provide essential water sources in this arid environment.

Evidence of the region's historical transit routes remains visible through the California Trail and various jeep trails that crisscross the foothills of Hauser Mountain. Small settlements and landmarks such as Bell Valley, Canyon City, and the local cemetery reflect a sparse but persistent community structure. The presence of a Gravel Pit and numerous wells indicates the local extractive and agricultural activities that sustained these remote outposts during the mid-20th century.
