There’s more beyond the big objects: exhibits cover First Peoples and Cascade Chinook history, Lewis and Clark’s passage through the corridor, natural history, Bonneville Dam, and community development. The museum also addresses spiritual history and local culture, so a visit can lean toward human stories as much as industry. Allow time to browse the topics that catch you; this is a museum stop rather than a quick roadside overlook. Older maps and records still use “Columbia Gorge Interpretive Center Museum,” the same Stevenson institution. Check the address when you navigate; Columbia Gorge Discovery Center & Museum is a separate museum in The Dalles, Oregon.
