About this map

The Russian River carves a deep, winding path toward the Pacific Ocean in this 1945 record of the Sonoma coast. Settlements like Duncans Mills and Monte Rio serve as focal points along the riverbanks, while the surrounding hills are dotted with agricultural and recreational landmarks. The presence of the Sonoma County Boy Scout Camp and Petaluma Boy Scout Camp north of the river highlights the area's mid-century role as a retreat destination.

Further south, the landscape transitions toward ranching and rural education, marked by the Big Buckhorn Ranch and Little Buckhorn Ranch. Local families were served by the Ocean District Sch and Ocean View Sch, which provided schooling for the coastal communities of Jenner and Duncan. The map also captures several shoreline features, including the distinctive Arched Rock and Penny Island at the river's mouth, offering a clear view of the coastal geography before modern development.
