This episode features the
talk Cataclysms on the Columbia: The Great
Missoula Floods, by Dr.
Scott Burns from Portland State University. The Missoula
Floods were a series of 80+ floods that happened in the Pacific
Northwest during the last ice age around 15,000 years ago, and they
dramatically shaped the geology and topography of Washington and
Oregon. Scott describes with enthusiastic detail what caused
the floods, who discovered them, what evidence was used to
prove that they happened, and some of the people continuing to
study them today. He also touches on Lewis & Clark, the
Willamette Meteorite, scientific grudge matches, what to ask
geologists on a road trip, and how to grow good wine grapes, among
