Cataclysms on the Columbia: The Great Missoula Floods
Scott Burns, a professor of geology at Portland State University will talk 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.
