How Do They Know? Major Findings About the Ice Age Floods

Registration is required.

Have you ever been watching a science program and wondered “How do they know that?” We briefly discuss the how and who “figured it out” regarding aspects of the Ice Age Floods, looking at five questions. These include how we know there was a huge glacial lake in western Montana thousands of years ago, how we know it drained rapidly perhaps a hundred times, about how many floods there were and when they occurred, where the floodwater came from, and about how long it took the floodwater to get to the ocean. We also go over which answers to these questions are still being debated by researchers.
