The Columbia River forms the central artery of this mid-century survey, dividing the rugged uplands of the Gifford Pinchot National Forest in Washington from the waterfall-rich cliffs of Multnomah County, Oregon. The era's transportation network is prominently displayed, showing the Spokane Portland and Seattle Railway and Evergreen Highway hugging the northern bank, while the Union Pacific and Columbia River Highway follow the southern shore.
