About Cataclysms on the Columbia: The Great Missoula Floods

Have you ever wondered how the Columbia River Basin has such a unique, varied and dynamic landscape? From scablands and dry channels in eastern Washington, to dramatic waterfalls on the Oregon side of the Columbia River, the region is a geologic wonderland. At the next Old St. Francis History Pub, journey with Scott Burns, Professor of Geology at Portland State University to the Pacific Northwest's past by learning about the last ice age floods that dramatically carved out and changed the Columbia River Gorge landscape over 10,000 years ago. These dramatic floods caused by the repeated breaking of an ice dam on glacial Lake Missoula in western Montana created the landscapes we know today including the scabland buttes, dry falls and dried river channels.
