2012 Map of Yucaipa

About this map

Yucaipa and Calimesa dominate the southern portion of this landscape, where suburban expansion meets the steep rising slopes of the San Bernardino Mountains. The northern half of the region is defined by deep drainages like Mill Creek Canyon and the Santa Ana River, which provide the hydrological foundation for the local valley communities. Traceable water features such as The Zanja irrigation canal and the North Fork Canal illustrate the engineering required to sustain agricultural and residential growth in this semi-arid climate. Between the urban centers and the peaks of Yucaipa Ridge, the Crafton Hills stand as a natural barrier, punctuated by Zanja Peak. Small settlements and landmarks like Dunlap Acres, Mentone, and the Jackson Ranch provide historical touchpoints for researchers studying the transition from early ranching and citrus farming to modern inland development.
