1943 Map of Vallecito

About this map

The Santa Rosa Mountains and Vallecito Mountains dominate this 1943 survey, which reveals the early developments and ranching outposts within Anza State Park. In the northern reach, Oasis serves as a vital maintenance station near the Salton Sea shoreline, while the central Borrego Valley shows a burgeoning community centered around Borrego School and the Desert Lodge. The map documents a transition from pioneer infrastructure like the Old Butterfield Stage Rd to industrial and agricultural ventures such as the Gypsum Mine and Flemming Saw Mill. Family-held lands including Brinniger Ranch, Wilson Ranch, and Las Arena Ranch illustrate the homesteading pattern of the era. Transportation networks are anchored by the Borrego Valley Road and the specialized Portland Cement RR in the southeast, reflecting a desert landscape being actively organized for recreation, resource extraction, and settlement.
