The Salton Sea shoreline dominates the northeastern corner of this 1940 survey, where the Salton Sea National Wildlife Refuge provides a sanctuary amidst the arid Colorado Desert. This era shows the early development of small agricultural and recreational outposts like Sea View Beach and Sandy Beach, while the interior remains a landscape of industrial exploration and water management. Landmarks such as the Diamond Bar Test Well, Harpers Well, and the Mesquite Drill Hole signal the search for resources in the harsh terrain. Further south, the Roosevelt Sch and the Elmore Desert Ranch represent the sparse but determined settlement of the Lower Borrego Valley. Transportation is defined by the Pacific Portland Cement Co RR skirting the Superstition Hills and numerous washes like San Felipe Creek that carve through the desert floor.
