Running Springs and Arrowbear Lake serve as the primary residential hubs within this section of the San Bernardino National Forest, where steep canyons and high-elevation plateaus define the landscape. The hydrology of the region is complex, with the Santa Ana River emerging in the south while numerous creeks like Deep Cr and Bear Cr drain the northern slopes. Notable landmarks such as Keller Peak and Government Peak provide significant relief, overlooking areas like Seymour Flat and Manzanita Flat.
