1957 Map of Bonneville Dam

About this map

Bonneville Dam and the Bridge of the Gods anchor this 1950s survey of the Columbia River Gorge, depicting the critical infrastructure and recreational landscape of the mid-century. The map shows the river corridor as a hub of heavy transport, with the Union Pacific and Spokane Portland and Seattle railroads lining opposite banks. Beyond the industrial and transit arteries, the map reveals a densely managed forest environment across the Gifford Pinchot and Mount Hood National Forest, connected by the Skyline Trail.
