About this map

The Colorado River defines the western edge of this agricultural landscape, forming the international boundary between the United States and Mexico. The survey captures the intricate irrigation network of the Yuma Valley during the mid-1960s, where the West Main Canal and South Main Canal distribute water across a grid of named laterals like the Ingraham Lateral and Cummings Lateral.

Settlement is concentrated at Gadsden and the border town of San Luis, supported by the Southern Pacific railroad line. Industrial infrastructure is noted through Grain Elevators at Somerton Siding and several Gaging Stations along the river. To the east, the terrain shifts abruptly from the irrigated valley floor to the arid Yuma Desert, while the northern portion includes a section of the Cocopah Indian Reservation.
