1959 Map of San Marcos Pass

About this map

Santa Ynez Mountains terrain dominates this late 1950s survey, showing a landscape defined by sharp canyons and the drainage of the Santa Ynez River. The presence of the San Marcos Sch, San Marcos Ranch, and several established campgrounds like Fremont Campground and Los Prietos Campground indicates a region transitioning into a recreational and residential corridor. Transportation is anchored by San Marcos Pass, while high-elevation routes like West Camino Cielo and East Camino Cielo trace the ridgelines. Significant backcountry infrastructure is evident through the Los Prietos Ranger Sta and various radio facilities, including a Radio Range Station in the southeast. Cultural landmarks such as Indian Cave and Painted Cave highlight the area's geological and archaeological interest within the Los Padres National Forest.
