1948 Map of York Mountain

About this map

York Mountain and the western slopes of the Santa Lucia Range define this mid-century landscape in San Luis Obispo County. The 1948 field survey reveals a terrain largely dedicated to cattle ranching and rural life, anchored by large holdings like Kentucky Ranch in the north and Santa Rita Ranch to the south. The distribution of Summit Sch, Asuncion Sch, and Oakdale Sch suggests a network of small, scattered school districts serving the remote families of the area. Water management is central to this environment, evidenced by numerous Windmill sites and the complex drainage of Willow Creek, Jack Creek, and Santa Rita Creek. The presence of an Indefinite Boundary between Paso De Robles and Asuncion reflects the early administrative divisions of the California land grants, providing a clear look at local land use before modern development reached the hills west of Templeton.
