About this map

The San Andreas Rift Zone bisects this coastal landscape, creating a dramatic linear valley that defines the geography between the Pacific and the Marin hills. This survey, updated in the early 1970s, documents the coastal communities of Bolinas and Stinson Beach during a period of transition, alongside the established Audubon Canyon Ranch and Woodville. The intricate shoreline from Bolinas Point to Duxbury Point is mapped in fine detail, revealing the complex bathymetry of Bolinas Lagoon and the sedimented flats around Kent Island.

Military history is evident through the Bolinas Military Res and Hill 64 Military Res, while industrial traces like the McKinnan Gulch Mine and a Copper Mine Tunnel hint at earlier resource extraction. Water management features prominently with Kent Lake and the Alpine Dam to the east, illustrating the engineering required to support regional growth while Point Reyes National Seashore preserves the coastal wild.
