1954 Map of San Geronimo

About this map

The valley of Nicasio and its surrounding coastal hills are defined here by a series of prominent water features and protected lands. The Nicasio Reservoir dominates the western topography, while to the south, the deep canyons of Samuel P Taylor State Park follow the course of Lagunitas Creek. The map documents a corridor of small communities including Forest Knolls, Lagunitas, and Woodacre strung along the Francis Drake Highway. Historical land grant boundaries, such as Corte Madera de Novato and San Geronimo, are still clearly marked, reflecting the region's ranching heritage. Local education and infrastructure are noted through landmarks like the Burdell School and the Filtration Plant near Stafford Lake. The rugged terrain is punctuated by significant peaks like Barnabe Mtn and Shroyer Mtn, with narrow passages like Devils Gulch cutting through the ridges.
