About this map

Santiago Reservoir dominates the lower southwest of this landscape, fed by the waters of Santiago Creek and held by the Santiago Dam. The terrain is defined by the steep canyons of the Santa Ana Mountains, where the Cleveland National Forest meets private ranching and industrial interests. Resource extraction is a visible legacy here, with the Claymont Clay Mine, Santiago Coal Mine, and Black Star Coal Mine marking the hillsides.

Modern infrastructure and recreation appear along the northern edge, where the Riverside Freeway follows the Santa Ana River near the Santa Ana Golf Course. A unique mid-century industrial marker is the Rocket Fuel Test Site located in the canyons north of the reservoir. Local history researchers can trace the old property boundaries of the Santiago de Santa Ana and Lomas de Santiago land grants, while hikers may recognize the rugged path of the Main Divide Truck Trail crossing the ridges near Sierra Peak.
