About this map

Sweetwater Reservoir and Lower Otay Reservoir dominate this mid-century portrait of southern San Diego County, reflecting the critical water management systems supporting the region's mid-century expansion. The landscape transitions from the residential developments of Spring Valley and Homelands in the northwest to the more isolated cattle country and ranch lands of the east. The Otay Mountains rise sharply in the south, where the map terminates at the United States-Mexico international boundary.

Key infrastructure like the Dulzura Conduit and Highway 94 trace the drainage patterns of Jamul Valley, connecting ranching outposts such as Ivanhoe Ranch and Honey Springs Ranch. Military and aviation interests are prominently represented by the Brown Field Naval Auxiliary Air Station near the border and the La Mesa Airport to the north. Educational and spiritual centers like The Oaks Sch and the Indian Church near Jamul anchor the smaller settlements of this era.
