Dry Falls Interpretive Center

About this museum

Once the largest waterfall on Earth, Dry Falls is now silent - and somehow more awe - inspiring for it. During the catastrophic Ice Age floods that reshaped the Columbia Plateau between roughly 15, 000 and 13, 000 years ago, more water poured over this basalt cliff in a matter of days than flows through all the world's rivers combined in a year. The result was a landscape of almost Martian strangeness: the channeled scablands of eastern Washington, carved by floods of unimaginable violence into coulees, buttes, potholes, and dry waterfalls that preserve the evidence of events so extreme that geologist J Harlen Bretz was dismissed as a crank for decades before his Ice Age flood theory was finally accepted. The Dry Falls Interpretive Center in Coulee City is the scientific and narrative gateway to understanding all of it. Exhibits explain the geology of the floods, the evidence preserved in the landscape, and the slow recognition by the scientific community of just how dramatically catastrophic processes can shape the planet. Standing at the viewpoint above the 3.5 - mile - wide, 400 - foot - tall dry cliff face after visiting the interpretive center transforms the view from merely spectacular to genuinely comprehensible. The center carries an extraordinary 4.7 - star rating from more than 1, 161 visitors - a remarkable number that reflects just how consistently this site impresses people. Located at 35661 HWY 17 North near Coulee City, Washington. Admission is free. The interpretive center makes an ideal stop on a driving tour of Grand Coulee Dam country, and it is a near - mandatory visit for anyone with any interest in geology, earth science, or the sheer drama of deep geologic time.
