About this map

Anza-Borrego Desert State Park dominates the eastern expanse of this 1982 map, revealing the intricate geography of the Borrego Valley and Borrego Badlands before modern development intensified. The map captures a complex cultural landscape of indigenous lands, including the Los Coyotes Indian Reservation, Mesa Grande Indian Reservation, and Santa Ysabel Indian Reservation.

To the west, the terrain rises into the Cleveland National Forest, where the Palomar Observatory stands as a landmark on the heights. The settlement pattern reflects the area's transition from high-desert ranching and small outposts like Borrego Springs and Warner Springs to recreation-oriented spots like Desert Lodge. Historic routes like 79 and s22 thread through the Valle de San Jose (Portilla), linking remote mountain communities like Julian and Kentwood in the Pines with the arid basins below.
