About this map

Santa Ysabel Indian Res. and the surrounding high country of San Diego County are captured here during a period of transition in the backcountry. The landscape is defined by vast land grants and reservations, including Coahuila Indian Reservation and Potrero Indian Reservation, interspersed with small settlements like Julian and Mesa Grande. The San Bernardino Meridian bisects the western reaches, marking the formal surveying of this complex terrain of valleys and peaks like Palomar Mt. and Agua Tibia Mountain.

Agricultural pockets are evident in the Valle De Pamo and Santa Maria Valley, where the town of Ramona serves as a hub. The map traces early transportation routes connecting isolated outposts such as Oakgrove and Witch Creek. This era reveals a network of springs and canyons, such as Sawyer Spring and Nigger Canyon, that were vital to the livestock and mining operations of the early twentieth century.
