1955 Map of Jamul

About this map

Savage Dam and the Lower Otay Reservoir anchor the southern landscape of this mid-1950s survey of the San Diego backcountry. The region's transition from agricultural ranching to strategic military and suburban growth is evident in the presence of the Brown Field Naval Auxiliary Air Station near the international border, contrasted with long-standing ranching operations like the Otay Ranch, Kuebler Ranch, and Monte Vista Ranch. The topography is dominated by the San Ysidro Mountains and San Miguel Mts, where the rugged terrain is carved by Dulzura Creek and Steele Canyon. Small communities and landmarks such as Jamul, Dulzura, and the Indian Church illustrate the localized settlement patterns before the extensive modern expansion of the San Diego metro area. The map also delineates the Otay (Dominguez) Grant Boundary and Otay (Estudillo) Grant Boundary, preserving the historical land grant divisions of the Spanish and Mexican eras.
