About this map

The San Andreas Rift Zone defines the geological character of this coastal landscape, running parallel to the shoreline through the Olema Creek drainage. This 1950s era survey captures the dramatic interface where the Pacific Ocean meets the steep coastal bluffs of Punta De Los Reyes (Sobrante). A series of freshwater basins, including Wildcat Lake, Pelican Lake, and Bass Lake, sit perched just inland from the surf, creating a unique hydrological pattern along the cliffs near Double Point.

Human presence is sparse on this rugged peninsula, primarily represented by the Lake Ranch and the Wildcat Military Res. The map provides a look at the land before later preservation efforts, showing the early road and trail network that connected these remote outposts. From the depths of Bear Valley to the secluded Ocean Lake, the terrain illustrates the complex topography shaped by active tectonic forces and coastal erosion.
