Crafton Hills separates the established residential and citrus corridors of Redlands and Mentone from the valley floor of Yucaipa. This landscape is defined by its complex water management systems, including the historical The Zanja irrigation canal, the Bear Valley High Line Aqueduct, and the Redlands Aqueduct which navigate the base of the San Bernardino Mountains. The map reveals a transition from the urban grid of Highland to the higher elevations of the San Bernardino National Forest, where features like Morton Peak and Cram Peak overlook Mill Creek Canyon. Educational development is anchored by Crafton Hills College atop its namesake ridge, while to the south, the community of Calimesa straddles the border between San Bernardino and Riverside counties near Wildwood Canyon.
