1940 Map of Yuma

About this map

The Colorado River and Gila River converge at a strategic desert crossroads on this 1940 survey, documenting the early development of the Lower Colorado River Valley. The city of Yuma serves as the hub of this arid landscape, featuring vital community infrastructure such as the Yuma General Hospital, the Indian Sch, and the Yuma Cem. The map illustrates a complex network of man-made waterways, including the Alamo Canal, Main Canal, and A Canal, which transformed the surrounding Yuma Desert into productive agricultural land.
