1940 Map of Healdsburg

About this map

The Russian River carves a winding path through this 1933 survey, anchoring the development of Sonoma County's northern valleys. The Northwestern Pacific railroad and the Redwood Highway run parallel through the river valley, connecting established hubs like Healdsburg, Geyserville, and Windsor. This corridor was the backbone of local industry and transport before the mid-century expansion of the regional road network, shown here with the intricate layout of early riverfront communities such as Del Rio Woods and Rio Nido.
