2017 Lecture Series October

Traveling is the theme for this year's lecture series. Plants and soil that originate in one place can often be found a continent away. This series explores some of the ways they got there. All lectures will take place in the Manor House at the Garden.

Thank you to Portland Nursery for sponsoring this year's series.

Description: Geologist Scott Burns joins us to share the story of the floods that are famous for carving out the Columbia Gorge but also might just explain the soil (or rocks) we find in our own back yards. The Missoula Floods are one of the greatest set of geological events to ever have occurred 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 unimaginable power and heights of up to 1000 feet. Scott's talk will focus on the story of J. Harlen Bretz's discovery and interpretation of the geological evidence of the floods throughout the Pacific Northwest 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 is a Professor of Geology and past Chair of the Dept. of Geology.  He actively helps local TV and radio stations and newspapers bring important geological news to the public.  Scott co-authored the book Cataclysms on the Columbia: The Great Missoula Floods with John Eliot Allen and Marjorie Burns.
