About this map

The Santa Maria River forms a natural dividing line between San Luis Obispo and Santa Barbara counties as it meets the Pacific Ocean in this late-1950s survey. The coastal landscape is defined by massive Sand Dunes and the industrial footprint of the Guadalupe Oil Field, where an Oil Sump and various Jeep Trails mark the exploitation of the region's natural resources.

South of the river mouth, the terrain rises sharply into the Point Sal Ridge and the Casmalia Hills. This area includes the protected coastline of Point Sal Beach State Park and the rugged outcrops of Mussel Rock and Lion Rock. The southern portion of the map is dominated by the northern extent of Vandenberg Air Force Base, showing early territorial boundaries like the Guadalupe Grant Bdy and Casmalia Grant Bdy.
