About this map

Morro Bay and the adjacent community of Los Osos anchor this coastal landscape, where the distinct volcanic peaks of the Irish Hills meet the Pacific. The prominent landmark of Morro Rock stands at the harbor entrance, while further inland, the chain of ancient volcanic plugs continues with Cerro Cabrillo and Hollister Peak. Between these heights, the Los Osos Valley provides a corridor for settlements like Baywood Park and Cuesta-by-the-Sea, which border the wetlands of Estero Bay.

South of the residential districts, the terrain shifts into the protected wilderness of Montana de Oro State Park. A complex network of trails, including the Hazard Peak Trl and Oats Peak Trl, winds through Hazard Canyon and up to summits like Valencia Peak. The map documents the interface of mid-century coastal development with conserved lands, showing the transition from the dense street grids of the coastal towns to the drainage systems of Chorro Cr and Islay Cr.
