1979 Map of Duncans Mills

About this map

The Russian River winds through the coastal mountains of Sonoma County toward its mouth at Jenner, anchoring a landscape defined by riverside settlements and the Pacific shoreline in the late 1970s. This USGS survey documents the transition from inland redwood country to the sea, where the river bypasses Duncans Mills and Bridgehaven before entering the Pacific. To the east, the river supports a cluster of resort and residential communities including Villa Grande, Monte Rio, and Guernewood Park.
