The Salton Sea shoreline dominates the northeast corner of this 1940 survey, where the water surface is recorded at 241 feet below sea level. This desert landscape is defined by its arid hydrology, showing a complex network of seasonal drainages including San Felipe Wash, Tule Wash, and Carrizo Wash. The map documents a period of early 20th-century desert infrastructure, from the Pacific Portland Cement line in the south to the developed leisure spots at Sea View Beach and Sandy Beach. Local history is preserved in the location of the Roosevelt Sch and the Elmore Desert Ranch, while industrial exploration is evident through the Diamond Bar Test Well and Harpers Well. The arid expanse of West Mesa and the Superstition Hills highlights the isolation of these early Imperial County settlements and desert outposts.
