About this map

Camp Cooke Military Reservation dominates the western landscape of this mid-century survey, illustrating the significant military footprint in Santa Barbara County. The Lompoc townsite is clearly defined by its grid, served by the Southern Pacific railroad and a nearby Municipal Airport. The map captures a transitional era for the region's heritage, marking the Mission La Purisima State Park and Mission La Purisima alongside the industrial activity at the Diatomaceous Earth Quarries in the hills to the south.

Rural life is preserved through labels for the Jalama Sch and San Julian Sch, while the expansive ranching history of the area is reflected in large land grants like San Julian and Cañada de Salsipuedes. Waterways such as the Santa Ynez River and Salsipuedes Creek wind through the Santa Rita Hills, providing a detailed look at the drainage patterns and topography that defined local settlement before late-twentieth-century development.
