About this map

The Crafton Hills and the southern slopes of the San Bernardino Mountains define this landscape, where the Santa Ana River basin meets the developing citrus and agricultural groves of the mid-1950s. The burgeoning community of Yucaipa serves as a central hub, flanked by the residential pockets of Dunlap Acres and Calimesa to the south. Local education and infrastructure are clearly marked, featuring Greenleaf School, Dunlap Sch, and the Yucaipa Jr High Sch.

Water management and natural resources are central to the area's layout, seen in the path of the Santa Ana River and the complex irrigation systems including the Zanja, Crafton Reservoir, and several Gaging Stations. Evidence of the region's mountain-to-valley economy appears through the Mill Creek Ranger Sta and Thurman Flat Guard Sta within the San Bernardino National Forest, alongside the tracks of the Southern Pacific railroad that connects these valley settlements.
