2015 Map of Casmalia

About this map

Vandenberg Air Force Base occupies a significant portion of the coastal landscape in this 2015 survey, where military operations meet the undulating terrain of northern Santa Barbara County. The map details the transition from the high ridges of the Casmalia Hills and Purisima Hills down to the sea-level expanses of the San Antonio Terrace and Burton Mesa. Small settlements and naming points like Casmalia, Shuman, and Devon are interspersed among a dense network of ranch and access roads, such as Point Sal Rd and W Lompoc Casmalia Rd. The drainage of San Antonio Cr carves through the central valley, defining the geography between the hills and the Pacific Ocean. This modern record illustrates the specialized infrastructure required for the aerospace mission of the base while preserving the names of the region's earlier ranching and railway history at locations like Antonio and Narlon.
