1943 Map of Jamul

About this map

Jamul and the surrounding ranchlands of southern San Diego County are documented here just as the region began its mid-century transition. The landscape is defined by the significant hydrological infrastructure of the Sweetwater Reservoir and Lower Otay Reservoir, the latter held by the Savage Dam. This era shows a network of established family operations and outposts, including the Mellor Ranch (Guard Sta) and several namesake holdings like Williams Ranch, Daley Ranch, and Kuebler Ranch. A notable remnant of the Great Depression is visible at Camp Minnewawa (CCC), reflecting federal investment in the local back country. These scattered settlements are connected by the early alignment of Highway 94, which snakes through the Jamul Mountains toward the international border with Baja California.
