Missoula Flood Tour - Sunday

  • Walla Walla Community College 500 North Tausick Way Walla Walla, WA, 99362 United States

This event is a repeat of the Saturday tour.

Join Whitman geology and environmental studies professor Bob Carson as we explore several stops while recreating the story of the Missoula Floods and how they shaped eastern Washington. 

Between 18,000 and 15,000 years ago, Clark Fork was repeatedly dammed by the Pend Oreille lobe of the Cordilleran ice sheet. Glacial Lake Missoula ruptured each ice dam, causing perhaps the greatest floods on Earth. 

First we’ll explore an overview of eastern Washington geology near the mouth of the Walla Walla River and Wallula Junction. Second, we’ll examine geological features such as Mazama ash and giant gravel bars along the mouth of Spring Creek. Last, we’ll take a short hike to the Two Sisters, a geologic feature along the Wallula Gap that overlooks the Columbia River. 

A Whitman professor since 1975, Bob hasled numerous field trips in and outside the United States and has been a popular Learning on the Land educator. He has published several books including Where the Great River Bends, a definitive history of the Wallula Gap area. His newest book is Many Waters: Natural History of the Walla Walla Valley and Vicinity

Whether you are a geology enthusiast, a novice looking to learn or just love to enjoy open spaces, this trip gives you a taste of everything!
