About this map

The San Ysidro Mountains dominate this borderland landscape, where the international boundary between the United States and Mexico cuts across steep ridges and deep canyons. The summit of Otay Mountain serves as a technological hub with several Radio Towers and a Radio Tower overlooking the terrain. To the north, the Dulzura Community Center anchors the small settlement area near Bee Canyon.

Tracing the drainage patterns of the Tijuana River and Cottonwood Creek reveals the importance of water sources in this arid region, marked by numerous named points like Donohoe Spring, Lupe Spring, and Echo Spring. Historical mining activity is evidenced by the Donohoe Mine and another unnamed Mine located near Mine Canyon. Access through the highlands is restricted to rugged routes such as the Minnewata Truck Trail and Otay Mtn Truck Trail, which converge at Doghouse Junction.
