Cataclysms on the Columbia: The Great Missoula Floods: Scott Burns - Lecture is full

Wednesday October 18, 7:00-8:30pm  

Description: Geologist Scott Burns will share the story of the Missoula Floods, some of the greatest geological events in North America. Between 15,000 and 18,000 years ago, these floods repeatedly inundated more than 16,000 square miles of the Pacific Northwest with heights of up to 1000 feet. Scott will focus on J. Harlen Bretz's discovery and interpretation of the geological evidence and how that explains the landscape we know today. Scott received his PhD from the University of Colorado and has taught for 47 years, 27 of them at Portland State University where he is a Professor of Geology and past Chair of the Dept. of Geology. Scott co-authored the book Cataclysms on the Columbia: The Great Missoula Floods with John Eliot Allen and Marjorie Burns.
