1964 Map of Grays Well NE

About this map

The Imperial Sand Dunes and their shifting Sand Hills dominate this borderland landscape, where the arid desert meets the engineering of the mid-20th century. The All American Canal cuts a stark line across the dunes, illustrating the massive water-diversion efforts vital to the region's agricultural development. Along the southeastern edge, the Colorado River serves as a natural boundary between California, Arizona, and Mexico, supporting life in the Yuma Valley. This survey captures the transition from the high, arid ground of Pilot Knob Mesa and the landmark Pilot Knob down to the irrigated corridor of the Cocopah Indian Reservation. The presence of the Southern Pacific railroad and the Pesch. Canal near the Well symbol highlight the infrastructure required to maintain human settlement in this extreme environment.
