2015 Map of Cucamonga Peak

About this map

The San Gabriel Mountains dominate the northern half of this landscape, where the Angeles National Forest and San Bernardino National Forest converge. High-altitude landmarks like Cucamonga Peak, Bighorn Peak, and Ontario Peak overlook a series of deep drainages including Cucamonga Canyon and Day Canyon. This transition from the high peaks to the valley floor defines the local geography, as mountain washes like Day Canyon Wash and Deer Canyon Wash extend south toward the developing residential and commercial grid.
