About this map

Montana De Oro State Park and the complex terrain of the Irish Hills dominate this coastal survey, which captures the industrial and natural intersection of the Central Coast in the mid-1960s. The shoreline is characterized by prominent landmarks like Point San Luis and the Diablo Canyon Power Plant, with its associated substation and filtration plant accessed via Diablo Canyon Road.

Detailed maritime features such as Whalers Island, Smith Island, and Lion Rock line the Pacific Ocean coast, while the interior is marked by deep cuts like Wild Cherry Canyon and Rattlesnake Canyon. This 1994 revision maintains the infrastructure of the era, including the Light Station at the point and various utilities like the Radio Tower and Water Tank, alongside the working landscape of the San Miguelito land grant.
