About this map

San Pablo Bay dominates this coastal landscape, where the waters meet the complex marshlands and shoreline points of Marin County. Near the northwestern edge, Black Point and Petaluma Point mark the transition toward the inland waterways, while Tubbs Island and Midshipman Point sit across the marshy reaches to the north. The southern shoreline is particularly detailed, revealing landforms such as China Camp Point, Buckeye Point, and Weber Point, alongside recreation-ready terrain like Miwok Meadows and Back Ranch Meadows.

This modern survey highlights the convergence of several major California counties, with boundary lines for Sonoma, Solano, and Contra Costa meeting in the open water. Low-lying elevations are defined by unique markers such as Turtle Back, Bullet Hill, and Chicken Coop Hill. The coastal geography is further traced by specialized paths including the Shoreline Trl and Back Ranch Fire Trl, which provide access to the bay's edge near Rat Rock Cove.
