1959 Map of Tierra Del Sol

About this map

The Campo Indian Reservation and the winding route of the San Diego and Arizona Eastern railway define the landscape of this high-desert region along the international border. In the late 1950s, the settlement of Tierra del Sol sat as a quiet mountain outpost, connected by the Tierra Del Sol Rd and situated near the prominent Tecate Divide. The terrain is characterized by high-elevation landmarks such as Rattlesnake Mountain and Boundary Peak, which overlook the small Lake Domingo and the seasonal drainages of Jewell Valley. This survey captures the rural infrastructure of San Diego County before significant modern development, showing the proximity of early 20th-century rail engineering to the United States Mexico boundary line.
