About this map

The Campo Indian Reservation occupies the western portion of this rugged borderland landscape, where the high desert meets the international boundary between the United States and Mexico. The small settlement of Tierra del Sol serves as a focal point along the tracks of the San Diego and Arizona Eastern railroad, which snakes through the uneven terrain of the southern backcountry.

Hydrology in this arid region is defined by scattered landmarks like Lake Domingo and Jewell Valley Creek, alongside several unnamed springs that supported early ranching and transit. The topographic crest of the Tecate Divide and the prominent Rattlesnake Mountain dominate the eastern view, marking a significant geographic transition. This 1950s survey illustrates the sparse, high-altitude development and vital rail infrastructure that connected this remote corner of San Diego County to the broader regional economy.
