1951 Map of Cayucos

About this map

Estero Bay and the coastal landscape of San Luis Obispo County are captured here just after the mid-century, showing the development of Cayucos and the evolving community of Morro Bay. The map highlights the coastal shelf between the Pacific Ocean and the rising peaks of the Santa Lucia Range, including prominent landmarks like Morro Rock and Valencia Peak. Further inland, the drainage patterns of Chorro Creek and Los Osos Creek define the agricultural corridors of the Los Osos Valley, where small rural schoolhouses like Sunnyside Sch and Los Osos Sch served local families.
