2012 Map of San Geronimo

About this map

Nicasio and its surrounding valleys anchor this survey of Marin County’s interior, where the landscape transitions from the open waters of Stafford Lake down through the wooded corridors of Redwood Canyon. The settlement pattern follows the winding course of the San Geronimo Valley, connecting Woodacre, Forest Knolls, and Lagunitas along the southern edge. The presence of Skywalker Ranch Rd north of Lucas Valley signals the modern cultural footprint on this traditionally rural ranching terrain. Significant public and recreational spaces are detailed, including Camp Taylor and the San Geronimo National Golf Course. The map also captures the intricate drainage system where Lagunitas Cr and Nicasio Cr meet, highlighting historic crossing points such as Shafter Bridge and the small siding at Jewell.
