1948 Map of Adelaida

About this map

Camp Roberts Military Reservation dominates the northern reaches of this coastal range landscape, illustrating the significant military footprint in San Luis Obispo County following the 1940s. The settlement of Adelaida serves as a focal point for local history, anchored by the Adelaida Cem and the nearby Lincoln Sch. The terrain is defined by a network of seasonal drainages, including Snake Creek, San Marcos Creek, and Las Tablas Creek, which carve through the hills and support isolated homesteads like White Ranch and Chimney Rock Ranch. The presence of a Landing Strip and multiple Windmills suggests a remote ranching economy evolving with mid-century infrastructure. This map captures the area after initial 1947 aerial surveys, with later purple updates documenting developments through the late 1970s.
