About this map

Jamul and the neighboring hills of North Jamul anchor this inland Southern California landscape, where the chaparral-covered slopes of the Jamul Mountains and San Ysidro Mountains meet a network of ranching and early residential outposts. The 1970s terrain is marked by a complex system of fire roads and truck trails, including the Minnewawa Truck Trail and the California Riding and Hiking Trail, which connect dispersed ranch sites like Honey Springs Ranch, Mountain Shadows Ranch, and Mocogo Ranch.

Resource extraction and community foundations are evident through features like the Peg Leg Mine and the Jamul-Las Flores Sch. The topography is defined by significant drainage systems such as Hollenbeck Canyon and Jamul Creek, which carve through the elevations between Lyons Peak and McGinty Mountain. This survey captures the area as it transitioned from a strictly rural ranching district toward more modern development near the Dulzura corridor.
