About this map

The dramatic central California coast is defined by shifting terrain and industrial presence in this late 1950s survey. The landscape is split between the massive Guadalupe Sand Dunes to the north and the uplifted Casmalia Hills and Point Sal Ridge to the south. Along the shoreline, the boundary between San Luis Obispo and Santa Barbara counties meets the sea at the mouth of the Santa Maria River.

Industrial activity and conservation coexist in this region, with the Guadalupe Oil Field established amongst the dunes while the Point Sal Beach State Park protects the rugged promontory near Point Sal and Lion Rock. The southern portion of the map transition into the northern reaches of Vandenberg Air Force Base, marked by a network of trails and jeep trails leading toward remote coastal points like Mussel Rock.
