1966 Map of California Valley

About this map

Carrizo Plain and the surrounding high desert of eastern San Luis Obispo County are captured here during a period of mid-century development. While much of the landscape remains defined by the dramatic geology of Syncline Hill and Freeborn Mountain, the emergence of California Valley as a planned community is evident through its grid of roads and the California Valley Airfield. Near the established settlement of Simmler, the Carrisa Plains Sch serves as a vital community anchor for the ranching families of the area. The map traces the natural drainage of San Juan Creek and Anderson Canyon, juxtaposing these ancient watercourses against the human imprints of remote landing strips and isolated Drill Holes. This survey preserves the exact footprint of a unique California land venture before many of its proposed roads were fully realized.
