1954 Map of Two Rock

USGS Topo · Published 1964

About this map

Americano Creek and Stemple Creek wind through the hills of southwestern Sonoma County in this mid-century survey. The landscape is defined by its rural education and transport networks, including the Petaluma and Santa Rosa rail line and numerous local schools like Eucalyptus School and Gold Ridge Sch. In the southern portion of the map, the Two Rock Ranch Station Military Reservation sits near the border of Sonoma and Marin counties, providing a glimpse into the Cold War-era defense footprint in northern California. Small agricultural hubs such as Bloomfield and Hessel are clearly delineated, showing the layout of farmsteads and rural roads before modern suburban expansion began to alter the region north of the Llano de Santa Rosa.
