1957 Map of Bonneville Dam

About this map

Bonneville Dam dominates the landscape of the Columbia River Gorge in this late 1950s survey, showing the complex industrial and transit network bridging Oregon and Washington. The map details the Union Pacific Railroad and Portland and Spokane Pacific Railroad hugging the riverbanks, alongside the iconic Bridge of the Gods and the Tooth Rock Tunnel. While the river serves as a primary corridor for commerce and power, the surrounding heights of the Gifford Pinchot National Forest and Mount Hood National Forest are marked by recreational and administrative outposts like the Wahtum Lake Guard Sta and Indian Mtn Lookout. Local life centers on settlements such as Stevenson, Cascade Locks, and Carson, while the era's tourism is evident at St Martins Hot Springs and Moffetts Hot Springs.
