Warner Springs serves as a central hub in this high-altitude landscape where the arid transition to the Anza Desert State Park begins. The survey details a rugged network of canyons and peaks within the Los Coyotes Indian Reservation and Coahuila Indian Reservation, revealing the isolated character of back-country San Diego County. Water sources are critical identifiers here, from Henshaw Lake in the southwest to the seasonal flows of Coyote Creek and Tule Creek.
