Topic: Changes on the Tatshinshini/Alsek - Total Blowout
Speaker: Bruce Ripley ~ Bruce is an active OWA member and past President of the club. He is the Chief Innovation Officer for the University of Idaho, College of Natural Resources and has worked in Forestry for over 30 years. He and his family has rafted all over the Western United States as well as in Canada. Including the Tatshinshini/Alsek Rivers.
Description: You ever wonder how rivers change and how long it takes for that to happen? How long has it taken to carve the Grand Canyon? Hells Canyon? Owyhee River Canyon? Rogue? And the list goes on. Have you ever noticed that sometimes the river changes more rapidly? Sometimes overnight? If you've run the Grand Canyon, Hance might ring a bell. Hance underwent a rapid and significant change a few years ago when Hance Creek blew out and changed the rapid into what it is today. Today there is a logjam on the Upper Middle Fork of the Salmon River that is blocking the entire channel and it came about from a single storm. We are going to talk about a couple rivers with nowhere near the information available and what can and did happen on those rivers back in August 2021. We are going to go back in time using satellite imagery and look at the before and after of several of these large events and also get a view from the river both before and after from pictures taken by some of your fellow club members.
Come on down, enjoy pizza and refreshments
