About this map

The central California coast around Estero Bay is documented here during the late 1930s, showing a landscape defined by its maritime geography and early petroleum infrastructure. Significant industrial development is visible at the Standard Oil Co Estero Bay Tankage and Loading Station just north of Morro Beach. The coastal settlements of Cayucos, Morro Bay, and Baywood Park are clearly established along the shoreline, connected by a network of primary and secondary roads.

Further inland, the topography rises sharply toward peaks like Hollister Peak and the volcanic prominence of Morro Rock, which stands as a landmark at the bay's entrance. The map provides a look at local education through the Banning Sch and agricultural land divisions within the Los Osos Valley. This 1937 revision utilized aerial photography from the Army Air Corps to update drainage and culture features, offering a precise view of the region before modern mid-century expansion.
