1948 Map of Cypress Mountain

About this map

The Santa Lucia Range dominates this late 1940s landscape, where mining operations and rural school districts define the cultural geography of San Luis Obispo County. Industrial activity is centered at the Klau Mine in the north and the Oceanic Mine to the west, linked by the winding paths of Cambria Road and Cayucos Road. These routes follow the natural drainages of the Santa Rosa Creek and Cienega Creek, illustrating how early infrastructure was dictated by the complex ridges of Cypress Mountain and Black Mountain. Local educational history is anchored by the Mammoth Rock Sch, situated along the road to the coast. In the southern portion of the sheet, the map details the San Geronimo area and the headwaters of Villa Creek and Cayucos Creek, providing a clear view of land divisions and the Indefinite Boundary Santa Rosa that shaped property and land use in this era.
