The San Bernardino Mountains dominate this high-desert and alpine interface, where the arid floor of Catclaw Flat meets the steep drainages of the San Bernardino National Forest. The landscape is defined by its dramatic hydrology, featuring the Whitewater Wild and Scenic River and complex canyon systems like Hell for Sure Canyon and Grape Canyon. The Pacific Crest National Scenic Tri winds through this terrain, providing a continuous corridor through the high country. For the geographer or local historian, the map preserves the intricate drainage patterns of Mission Cr and its tributaries, alongside prominent peaks such as Kitching Peak and the geological feature known as Red Dome. The boundary line between San Bernardino Co and Riverside Co bisects the region, marking the administrative division across this topographic expanse.
