About this map

Lake Henshaw anchors the northeast corner of this San Diego County survey, where the San Luis Rey River feeds into the reservoir near Valle De San Jose. The landscape is defined by the high ridges of the Cleveland National Forest, including Black Mtn with its Black Mtn Lookout and the prominent Middle Ridge. Significant cultural markers include the Santa Ysabel Indian Reservation and the settlement of Mesa Grande, which is supported by the Mesa Grande Sch. Economic activity in these uplands is represented by the Himalaya Mine and Esmeralda Mine, while ranching history is evidenced by the Almond Ranch in Pamo Valley. A remote Landing Strip and rugged routes like the Mesa Grande Truck Trail illustrate the mid-century transportation network through this varied terrain of flats and canyons.
