1948 Map of Paso Robles

About this map

The Salinas River corridor defines this Central Coast landscape, anchoring a series of historic settlements from the San Miguel Mission in the north to the expanding grid of Paso Robles in the south. The 1948 survey, updated with 1970s revisions, highlights a period of significant regional growth marked by the presence of the Camp Roberts Military Reservation and the development of the Paso Robles Municipal Airport. Transport and infrastructure are central to the map's story, with the Southern Pacific railroad and U.S. Route 101 tracing the river valley past smaller points like Wellsona and the Old Adobe. Local institutions such as the El Paso De Robles Sch (Reformatory) and the Fair Grounds appear alongside family-named terrain like Norn Hill and Ranchito Canyon, offering a detailed view of the area's agricultural and institutional evolution.
