About this map

The Colorado River defines the landscape of this borderlands region, serving as the physical boundary between Riverside County, California, and Yuma County, Arizona. The city of Blythe dominates the western bank, shown during a period of expansion with detailed layouts for Todd Park and East Blythe. Essential transportation infrastructure of the mid-20th century is visible, including the Ehrenberg Bridge carrying U.S. Highway 60-70 across the water and the Atchison Topeka and Santa Fe railroad line.

Agricultural and civic development is highlighted by an extensive network of irrigation canals, such as the C and D Canal and D-10 Canal, which supported the Palo Verde Valley. Regional services are marked by Palo Verde College and Palo Verde Hospital, while the desert terrain to the east is etched with numerous washes like Cinnabar Wash and Weaver Wash. The presence of both the California Checking Sta and Arizona Checking Station underscores the importance of this crossing point for travelers and commerce during the era.
