The Salton Sea shoreline and the harsh desert landscape of the Chocolate Mountains dominate this wartime survey of the Colorado Desert. Settlement is sparse, clustered primarily along the Southern Pacific railroad line where small stops like Bombay Beach, Pope, and Frink provided critical access points for local industry and transport. The map documents an essential moment in regional water engineering, showing the Coachella Canal cutting across the alluvial fans and the presence of several Artesian Well sites and irrigation features like the Z Drain and W Lateral Canal. Local industry is anchored by the Imperial Salt Co on the sea's edge, while family-named sites such as Greer Ranch and Haubaugh hint at the rugged agricultural efforts of the era. The boundary between Riverside and Imperial Counties bisects the northern reach of the quadrangle.
