About this map

Russian River meandering through the coastal mountains of Sonoma County defines the character of this landscape, where the redwood-shaded canyons meet the Pacific Ocean. The namesake village of Duncans Mills serves as a central hub, accompanied by the historic Duncans Mills Cemetery and a network of riverfront settlements including Villa Grande, Guernewood Park, and Monte Rio. The intricate network of steep ravines is evidenced by descriptive local names such as Schoolhouse Gulch, Sawmill Gulch, and Slaughterhouse Gulch, hinting at the area's industrious past and rugged topography.

Along the coast, the San Andreas Fault line runs parallel to the shore near Wrights Beach and Shell Beach. The map details the transition from the river valley's resort communities to the wind-swept shoreline at Jenner and Duncans Point. From the inland heights of Mt Heller to the sea-level expanses of Penny Island and Freezeout Flat, the document provides a clear view of the region's geography prior to modern development shifts.
