About this map

San Luis Obispo sits at the heart of this Central Coast landscape, appearing as a compact urban center flanked by distinctive peaks like Cerro San Luis Obispo and Terrace Hill. The pre-war geography is defined by the Southern Pacific railroad corridor, which winds through the Cuesta Pass to connect the city with northern settlements like Santa Margarita and Atascadero. Notable institutional landmarks include the California Polytechnic School and the California National Guard Camp near Chorro Creek.

Rural life is marked by several outlying school districts such as Stowe Sch, Parkhill Sch, and Irish Hills Sch, reflecting the distributed ranching and agricultural communities of the era. The terrain transitions from the volcanic plugs of the San Luis Range to the vast acreage of the Los Padres National Forest, while aviation is represented by Clark Field (Airport) and an Airway Beacon near Thyle.
