1954 Map of Yucaipa

About this map

The Crafton Hills and San Bernardino Mountains dominate this mid-century portrait of a changing agricultural and residential landscape. While the northern reaches are preserved within the San Bernardino National Forest, featuring landmarks like Morton Peak and the Thurman Flat Guard Sta, the lowlands show the expansion of Yucaipa and Calimesa along the San Bernardino and Riverside County line. The importance of water management is evident in the complex network of the Santa Ana River, the historic Zanja, and the Wilson Flood Control Basin. Educational hubs such as the Greenleaf School and Dunlap Sch serve the growing neighborhoods of Dunlap Acres and Crafton. The presence of the Grafton Hills Airport and a Fish Hatchery reflects the diverse land use in the San Bernardino Valley during this period of post-war growth.
