Spirit Whales and Sloth Tales: Fossils in Washington State

Zoom Meeting

The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute’s next program will be Tuesday, December 12 at 7:00 PM. This is a hybrid program, with the speakers presenting remotely via Zoom from Seattle. For those who are not computer- or Zoom-savvy, you can attend in-person for a screening at the Wenatchee Valley Museum and Cultural Center, 127 S. Mission, Wenatchee. Or at home via Zoom link:  https://us02web.zoom.us/j/84520197937 Webinar ID: 845 2019 7937 In Washington, you are never far from the past, including evidence of plants and animals that came before. Fossil flowers in Republic. Trilobites near the Idaho border. Primitive horses on the Columbia Plateau. Tracks of giant birds near Bellingham. Curious bear-like creatures on the Olympic Peninsula. With abundant and well-exposed rock layers, Washington has fossils dating from Ice Age mammals from only 12,000 years ago, to marine invertebrates more than 500 million years old. Join co-authors Dr. Liz Nesbitt and David B. Williams as they discuss this rich array of past life, which is featured in their new book, "Spirit Whales and Sloth Tales: Fossils in Washington State"— the first book ever on fossils in the state! Why did they choose the fossils they did? What is the new science that has allowed paleontologists to tease out the 500-million-year long story of life in this region? Liz Nesbitt is curator emerita of invertebrate and micropaleontology at the Burke Museum. David B. Williams is an author, naturalist, tour guide, and Curatorial Associate at the Burke Museum. Please sign in, or show up, at 7:00 PM, December 12! The program is free and open to the public.

Dr. Scott Burns – Ancient Ice Age Floods Before the Missoula Floods

Tualatin Heritage Center 8700 SW Sweek Drive, Tualatin, OR, United States

Come and Learn About The Unfolding Story of Ancient Ice Age Floods in the Pacific Northwest Ages End - Stev Ominski We have had Ice Age Floods in the Pacific Northwest over the past 2.8 million years. We mostly concentrate on the last ones which are called the Missoula Floods that happened between 15,000-20,000 years ago. But there is an unfolding story in the Pacific Northwest of many Ice Age Floods before the Missoula Floods. Erica Medley, an MS student of Scott Burns, did her thesis on the topic and discovered many outcrops of these ancient floods which are rarely discussed. Dr. Burns will talk about these oft-forgotten floods and the very interesting story of these neglected Ancient Ice Age Floods in the Pacific Northwest Come and learn more about these very interesting older Ice Age Floods, Thursday, Feb. 15, 2024 at 7:00 PM (Pacific Time) Live at Tualatin Heritage Center, 8700 SW Sweek Dr., Tualatin, OR 97062 Or on Zoom - Click here to join via ZOOM Meeting ID: 827 0148 6070 Passcode: 265961 Dr. Scott Burns taught geology for 54 years in Switzerland, New Zealand, Washington, Colorado and Louisiana before coming in 1990 to Portland State University. He loves talking about the geology of the Pacific Northwest and this subject that is so many times neglected.

David Ellingson – “Fossil Dig in Woodburn, OR”

Tualatin Heritage Center 8700 SW Sweek Drive, Tualatin, OR, United States

The Willamette Valley at the time of the Ice Age Floods, 18,000 - 15,000 years ago, was backwater for massive floodwaters coming through the Columbia River Gorge multiple times. It was known as temporary Lake Allison for the geologist who first studied it as a lake. David Ellingson, a biologist and paleontologist, teaches paleontology at Woodburn High School in Woodburn Oregon. Here he has led his students in an ongoing dig for many years for fauna and megafauna fossil bones. The dig will continue in the same location starting in early July this summer. David has spoken to our group several times, always bringing fossils for us to view. We look forward to welcoming David in-person & online for a very interesting evening. When: Thursday, May 16, 2024 @ 7:00 PM PDT Where: Simultaneous In-Person Live and ZOOM presentation from Tualatin Heritage Center, 8700 SW Sweek Drive, Tualatin, OR 97062 For more information contact: LowerColumbia@iafi.org If you cannot attend the in-person meeting at THC, please join us online Click here to join the Zoom meeting Meeting ID: 869 4651 3479 Passcode: 322382.

Dr. Jerome Lesemann Presents “Subglacial/proglacial mega floods from the Cordilleran Ice Sheet on the Channeled Scablands”

Bellevue College Building L Room 219 3000 Landerholm Cir SE, Bellevue, WA, United States

From Wikipedia Glacial Lake Missoula is most commonly invoked as the sole source of water to form the Channeled Scabland. However, early work by Bretz (and others) suggested more direct contributions of meltwater from the Cordilleran Ice Sheet to explain formation of some Scabland flood tracts. In some cases, these contributions may have been subglacially routed. This presentation will examine new research on Moses Coulee - one of the more enigmatic Scabland coulees – that suggests subglacial meltwater flows best explain the erosional patterns of the coulee and its perplexing lack of connectivity to other Scabland flood routes. Further, the presentation will examine new evidence for proglacial (Mega) floods during deglaciation of the Cordilleran Ice Sheet that may also contribute to formation of flood features such as giant bars along the Columbia River Valley. The presentation highlights the need for greater integration of Cordilleran Ice Sheet hydrology in the interpretive framework of the Channeled Scabland. As a workup to this presentation please familiarize yourself with the IAFI News article, "Moses Coulee: Unveiling the Mystery of a Colossal Ice Age Scar", that gives an overview on this subject. Dr. Jerome Lesemann obtained his PhD from Simon Fraser University. He currently teaches in the Earth Science Department at Vancouver Island University in Nanaimo, BC. His research interests are in Quaternary geology and sedimentology with a focus on glacier processes and ice sheet hydrology. He has had an interest in the Channeled Scabland for over two decades, with a particular focus on the dynamics of the Cordilleran Ice Sheet along the northern reaches of the Channeled Scabland. Date: 20 May 2024 at 7:00pm Location: Bellevue College, Bldg. R, Rm. 103 or click on Zoom link:   https://us02web.Zoom.us/j/82985244730

Exploration of Geomorphic Features in Lake Chelan with an Underwater Remotely Operated Vehicle (ROV)

Wenatchee Valley Museum and Cultural Center 127 S. Mission, Wenatchee, WA, United States

The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday, June 11 at 7:00 PM, at the Wenatchee Valley Museum and Cultural Center, 127 S. Mission, Wenatchee. Or via Zoom link https://us02web.zoom.us/j/84520197937 Our speaker will be Philip Long of the Lake Chelan Research Institute (LCRI). Phil will talk about “Exploration of Geomorphic Features in Lake Chelan with an Underwater Remotely Operated Vehicle (ROV)” Swath bathymetry, chirp sub-bottom reflection profiles, and sediment cores…. These were techniques recently used by the U.S. Geological Survey (June 2023) to collect data from Lake Chelan, WA, The resulting information has provided insights into late- and post-glacial history of Lake Chelan. In addition, LCRI’s ROV dives have distinguished bedrock from till on lake bottom sediment profiles, and have directly observed landslide scarps, debris aprons, and other geomorphic features of interest to many of us here. Some of the features on the bottom of Lake Chelan resemble surface glacial features we are familiar with on the Waterville Plateau! Moraines, kames, drumlins, kettles, underwater landslides…. Find out what’s going on at the bottom Lake Chelan!   The program is free and open to the public.
