1959 Map of Casmalia

About this map

Vandenberg Air Force Base dominates the central coastal landscape of Santa Barbara County in this mid-century survey, illustrating a massive military footprint over the historic Rancho Jesus Maria and Rancho San Antonio lands. The topography is defined by the heavy industry of the Casmalia Oil Field and the Airox Mine to the northeast, while the Southern Pacific rail line cuts through the Sand Dunes and coastal terrace. Small railway stops and ranching outposts like Schumann, Antonio, and Tangair represent the rural infrastructure supporting the region before suburban expansion. To the south, the San Antonio Creek meanders through the San Antonio Valley toward Purisima Point, providing a glimpse into the natural drainage patterns and land-grant boundaries that shaped the Santa Maria area's development.
