About this map

Bonneville Dam anchors this landscape where the Columbia River separates Washington and Oregon. During this period in the late 1970s, the map documents significant infrastructure including a powerhouse under construction and extensive fish ladders at Bradford Island. The settlement of North Bonneville sits at the river’s edge, adjacent to the Burlington Northern railroad line that follows the northern bank. Across the water, Cascade Locks serves as a hub for river transit and aviation via the Cascade Locks Airport.

Upriver, the town of Stevenson borders Rock Cove, while the surrounding terrain is defined by the high elevations of the Gifford Pinchot National Forest and Mount Hood National Forest. Hikers can trace the Pacific Crest Nat Scenic Trail as it winds past landmarks like Sacajawea and Papoose Rocks and Aldrich Butte. This survey provides a precise look at the river-and-rail economy before the further modernization of the Columbia River Gorge.
