The international border between California and Baja California anchors this southern San Diego County survey, highlighting a landscape defined by ranching, mountain valleys, and the transition into the high desert. Just north of the United States and Mexico boundary, the border town of Campo serves as a focal point, hosting U S Customs and a U S Military Reservation. The San Diego and Arizona Eastern railroad winds through the complex topography, connecting stops like Hipass Sta and Pueblo Siding. Numerous tribal lands, including the Campo Indian Reservation, La Posta Indian Reservation, and Manzanita Indian Reservation, are interspersed with private holdings like Coogan Ranch and Castle Rock Ranch. The road network follows established paths like U S Highway 80, which passes through mountain communities such as Boulder Oaks and Live Oak Springs.
