1959 Map of Tierra Del Sol

About this map

Tierra del Sol sits at the heart of this high-desert landscape in the late 1950s, positioned just north of the international border between the United States and Mexico. The terrain is defined by the prominent Tecate Divide and Rattlesnake Mountain, which overlook the eastern stretches of the Campo Indian Reservation. A critical transport artery, the San Diego and Arizona Eastern railroad, winds through the southern portion of the quadrangle, tracing the contours of the land near the border. Water sources appear as scattered features in this arid environment, including Lake Domingo, several unnamed Springs, and the seasonal flow of Jewell Valley Creek. The presence of numerous bench marks and triangulation stations like Boundary Peak indicates the precision required for mapping this varied topography along the California and Baja California line.
