1967 Map of Yucaipa

About this map

Yucaipa and its surrounding valleys are captured here during a period of significant suburban expansion, evidenced by the purple-tinted updates that overlay the earlier survey. The landscape transitions from the rugged foothills of the San Bernardino National Forest, featuring landmarks like Cram Peak and Morton Peak, down into the developed grids of Redlands and Mentone. Water management is central to the area's layout, with percolation basins near the Santa Ana River and the Wilson Flood Control Basin regulating flow from Oak Glen Creek. Educational and civic growth is prominent, shown through the sites of Yucaipa High Sch, Crafton Sch, and the Mill Creek Ranger Station. The map illustrates the era's evolving residential patterns as small settlements like Dunlap Acres and Calimesa begin to merge into a more continuous urban fabric while maintaining proximity to the wild terrain of the Crafton Hills.
