About this map

The Mesa Grande Indian Reservation and the sprawling waters of Lake Henshaw anchor this late-twentieth-century study of San Diego County's back country. Situated within the Cleveland National Forest, the landscape is defined by the sharp transition from the Mesa Grande plateau down into the deep basins of Pamo Valley and the Temescal Valley. The map documents a rugged interior economy where old mining claims like the Himalaya Mine, Esmeralda Mine, and Shenandoah Mine dot the slopes of Gem Hill and Angel Mountain.

Land use patterns reflect a complex history of land tenure, from the colonial-era boundaries of the Valle de San Jose Grant and Guejito Grant to the operational infrastructure of the Henshaw Fire Station and Work Center. High-altitude springs like Black Mountain Spring and remote outposts such as Almond Ranch signify the enduring importance of water and ranching in this Mediterranean climate zone before modern development reached these higher elevations.
