A petroglyph whose eyes seem to look straight at you, "She Who Watches" or "Tsagaglalal" is the logo for this museum. Sitting among the dramatic basaltic cliffs on the north bank of the Columbia River Gorge, the museum explores the life of the gorge: its history, culture, architecture, legends, and much more. Younger guests enjoy the reenactment of the gorge's formation in the Creation Theatre, and the 37-foot-high fish wheel, a device like a mill wheel equipped with baskets for catching fish, from the 19th century. Historians appreciate studying the water route of the Lewis and Clark Expedition. There's also an eye-opening exhibit that examines current environmental impacts on the area.
