The border city of Calexico serves as the focal point of this mid-century survey, sitting directly against the United States-Mexico international boundary. The landscape is a testament to the engineering required for desert agriculture, dominated by a dense grid of irrigation infrastructure including the massive All American Canal, the Ash Main Canal, and the Alamitos Canal. Local social life in the 1950s is anchored by institutions like Union High Sch, the Hoffman Sch, and a public Swimming Pool in the city center. Beyond the urban limits, the map documents the Labor Camp and the Jasper-Alamitos Union School, showing how the labor and educational needs of the Imperial Valley were distributed across the irrigated fields. Notable landmarks such as Radio Station KICO and the Mountain View Cemetery provide specific points of interest for genealogists and local historians.
