About this map

Jamul and the surrounding ranchlands of San Diego County are captured here during a period of transition in the early 1970s. The landscape is defined by its agricultural and residential evolution, featuring numerous established properties such as the Mountain Shadows Ranch, Skyline Ranch, and Bar HL Ranch. Infrastructure of the era is evidenced by Radio Facilities near Lyons Peak and a network of truck trails, including the Minnewawa Truck Trail and Wisecarver Truck Trail, which cut through the Cleveland National Forest.

To the south, Dulzura and Engineer Springs sit along the winding canyon roads, while the St Francis Xavier Cemetery serves as a localized landmark for genealogists. Resource extraction is noted at the Peg Leg Mine and various quarries and gravel pits, indicating the area's continued utility. The rugged topography of the San Ysidro Mountains and Jamul Mountains frames these small settlements and family-named valleys like Lee Valley and Bratton Valley.
