1954 Map of San Geronimo

About this map

The rugged topography of Marin County is defined by the steep ridges and narrow valleys surrounding Samuel P Taylor State Park and Tomales Y Baulines (Garcia) State Park. The map captures a mid-century landscape where small residential clusters like Forest Knolls, Lagunitas, San Geronimo, and Woodacre follow the path of San Geronimo Creek. An interesting remnant of earlier infrastructure is the Old Railroad Grade winding through the southern hills, marking the path of the North Pacific Coast Railroad long after its tracks were gone. Further north, the landscape shifts to open ranch land and wide grant boundaries like Corte Madera De Novato, centered on the small village of Nicasio. Local education is anchored by rural institutions such as the Nicasio School and the Lagunitas District School, reflecting the scattered settlement patterns of the era.
