The border city of Calexico anchors this late-1950s survey of the Imperial Valley, where the intricate irrigation network of the All American Canal and the Alamo River defines the landscape. The map reveals the critical infrastructure supporting agriculture along the United States Mexico border, featuring an extensive system of drains and canals such as the Hemlock Canal and East Highline Canal. Local educational history is well-represented through several institutions, including Union High Sch, Rockwood Sch, and the Jasper-Alamitos Sch. Beyond the residential streets of the city, small rural hubs like Bonds Corner and the Labor Camp appear alongside specialized landmarks like the Radio Sta (KICO) and the Mountain View Cem. The transition from the engineered valley floor to the desert is marked by the East Mesa, where a Jeep Trail winds through the arid terrain.
