The Coahuila Indian Reservation and Los Coyotes Indian Reservation anchor the highland terrain of this 1940s War Department survey. This interior landscape is defined by the headwaters of the San Luis Rey River, which flows southwest toward Lake Henshaw. The settlement of Warner Springs serves as a primary hub, situated near the thermal waters of Agua Caliente. To the north, the Chihuahua Valley and Terwilliger Valley provide level ground amidst the ridges of the Cleveland National Forest.
