1955 Map of Jamul

About this map

The Brown Field Naval Auxiliary Air Station and the associated Brown Field Bombing Range dominate the southern landscape just north of the United States Mexico border. This mid-century survey captures a period of transition for San Diego County, where burgeoning communities like Spring Valley and Jamul sit alongside expansive agricultural holdings such as Otay Ranch and Ivanhoe Ranch. Water management is a defining feature of the region, illustrated by the presence of Sweetwater Reservoir, Upper Otay Reservoir, and Lower Otay Reservoir, which served the growing coastal population. Rugged peaks like Lyons Peak and Mother Miguel Mtn break up the valleys, while the Cleveland National Forest covers much of the eastern terrain. Traces of early social infrastructure remain visible through labels for Indian Church, The Oaks Sch, and the La Mesa Airport.
