About this map

Santa Ysabel Indian Reservation and the Mesa Grande Indian Res landholdings anchor this late-1940s survey of the San Diego County high country. The landscape is a network of rugged canyons and mountain peaks, including Angel Mtn and Black Mtn, interlaced by several truck trails for fire and forest access. Significant mining activity is recorded here, with locations like the Esmeralda Mine, Himalaya Mine, and the Shenandoah Mine (Aband) appearing near the Cleveland National Forest boundary.

Local life centers on the community of Mesa Grande and the Mesa Grande Sch, while the massive footprint of Lake Henshaw dominates the northeastern corner. The presence of the Almond Ranch in Pamo Valley and remote outposts like Snobel Valley suggest a sparse but established ranching economy. This sheet also captures seasonal water features such as Washtub Falls and the headwaters of the Sun Luis Rey River.
