About this map

The Carrizo Plain landscape dominates this mid-1960s survey, illustrating a remote stretch of San Luis Obispo County where agricultural aspirations met the arid reality of the California interior. The settlement at California Valley is shown during a period of planned development, featuring a grid of unimproved dirt roads, a Po, a Fire Sta, and the California Valley Airfield. This human footprint contrasts sharply with the western half of the map, which is defined by the steep rises of Freeborn Mountain and Hubbard Hill.

Water management is the defining characteristic of this terrain, evidenced by numerous Well and Drill Hole markers scattered across the plain. The drainage patterns of San Juan Creek and Buckhorn Creek carve through the foothills, while the Syncline Hills provide a distinct geological boundary to the north. Local civic life is anchored by the Carrisa Plains Sch and the small station at Simmler, serving a dispersed ranching community.
