Santiago Peak (Old Saddleback) and Modjeska Peak dominate this 1954 survey of the Santa Ana Mountains, marking the rugged divide between Orange and Riverside counties. The landscape is a complex network of canyons and fire roads, including the Main Divide Truck Trail and Silverado Truck Trail, which provided critical access through the Cleveland National Forest before widespread modern development.
