About this map

San Geronimo and its neighboring valley communities of Woodacre, Forest Knolls, and Lagunitas anchor the southern portion of this landscape along Sir Francis Drake Blvd. This area represents a transition from residential enclaves into the protected wilderness of the Golden Gate National Recreation Area. To the north, the waters of Nicasio Reservoir and Stafford Lake dominate the drainage basins of Arroyo Sausal and Novato Cr, reflecting the region's managed water resources.

Local history is marked by specific landmarks such as the Taylors Grave Site near Deadmans Gulch and the Shafter Bridge at the settlement of Shafter. The terrain is defined by prominent ridges and peaks, including Big Rock Ridge and Barnabe Mtn, which separate deep canyons like Wildcat Canyon and Redwood Canyon. The network of local roads, such as Nicasio Valley RD and Lucas Valley RD, follows the natural contours of the land, connecting these dispersed mountain settlements.
