About this map

The Nicasio Reservoir dominates the western landscape of this mid-century survey, its expansive waters surrounded by the legacy of early California land grants like Corte Madera de Novato and Bolinas y Baulines (Garcia). The document highlights a string of settlements along the southern corridor, including San Geronimo, Forest Knolls, and Lagunitas, linked by the Sir Francis Drake Highway. Local education is anchored by rural institutions such as the Burdell School near Stafford Lake and the Lagunitas District School.

Conservation efforts are evident in the sprawling grounds of Samuel P Taylor State Park, protecting terrain near Barnabe Mtn. The map's 1971 revisions, shown in purple, reveal the gradual expansion of residential areas around Woodacre and Nicasio, while high points like Shroyer Mtn and the Big Rock Ridge define the steep topography of central Marin County before the intensified suburban growth of the late 20th century.
