    Ice Age Floodscapes of the Pacific Northwest

    The Reach Museum 1943 Columbia Park Trl , WA, Richland, WA, United States

    Ice Age Floodscapes of the Pacific Northwest: A photographic exploration Geologist and author Bruce Bjornstad will present a bird's eye view of the Ice Age megafloods that impacted the Pacific Northwest as recently as 14,000 years ago and shaped the landscape of the mid-Columbia basin. Bruce's presentation will be a stunning picture show of amazing drone photos from all over the Pacific NW flood plain. This will be  a hybrid meeting, live and livestreamed via ZOOM, on Tuesday evening at 7PM. We will post it to Youtube after editing.  It will be great. Bruce Bjornstad is a retired geologist with degrees from the University of New Hampshire and Eastern Washington University living in Richland, Washington. During his career Bjornstad has written numerous documents and reports on the geology of eastern Washington as well as two geologic guidebooks "On the Trail of the Ice Age Floods" that tell of the transformation of the Pacific Northwest as recently as 14,000 years ago. Bjornstad is also the creator of the online YouTube Channel  “Ice Age Floodscapes”. Most recently, Bjornstad has published a new, full-color, coffee-table-style book titled: “Ice Age Floodscapes of the Pacific Northwest: A Photographic Exploration”. Bruce will have books available for purchase. This presentation is free to attend. It begins at 7 pm, Tuesday, February 20, at the REACH Museum, 1943 Columbia Park Trail, Richland, WA Or join the Zoom Meeting, 7PM - 8:30PM Please note, the Zoom link that was listed before Feb. 8 was a mistake, the correct link is: https://us06web.zoom.us/j/88136774109?pwd=zLCbrWxCXIzqJ5TK2bNshKCtRCCaRh.1 Meeting ID: 881 3677 4109 Passcode: 726292

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

    Zoom Meeting

    Join in to 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 Join on Zoom to learn more about these very interesting older Ice Age Floods, Tuesday, Nov. 12, 2024 at 7:00 PM (Pacific Time) Only on Zoom - Click Here to Join Zoom Meeting Meeting ID: 867 5486 6921 Passcode: 342192 One tap mobile: +12532158782,,86754866921# Meeting ID: 867 5486 6921 Find your local number: https://us02web.zoom.us/u/kdugrTW42K 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.

There’ll be opportunities to explore storied Gorge wildflowers and native plants, geology and winery field trips, whitewater rafting, a membership meeting/dinner and a presentation by the ever-entertaining Nick Zenter. Friday, May 2nd, will be action packed with activities during the day. Choose between a guided Spring Wildflower Walk, a Journey Through Terroir field trip, an Unveiling the Gorge field trip (repeated on Sunday, May 4).

Friday evening will feature our members meeting and dinner, followed by an entertaining and informative presentation by the inimitable Nick Zenter exploring and geolocating J Harlan Bretz’s field notes.  Jim O'Connor Richard Waitt Saturday, May 3rd, will feature the main Ice Age Floods Gorge Geology Field Trip – Explore evidence of the Ice Age Floods in the Columbia Gorge led by USGS expert geologists Jim O’Connor and Richard Waitt. This  field trip will examine the geology of the Columbia River Gorge with emphasis on the effects of the Ice Age Missoula floods, examining key sites and discussing the latest research. Learn more about the Missoula Floods, explore dramatic flood landforms, and enjoy beautiful vistas, lunch at the Deschutes River Park (order a box lunch or bring your own), and a no-host afternoon recap at Maryhill Winery.

    EVOLUTION OF THE COLUMBIA RIVER SYSTEM

    The Reach Museum 1943 Columbia Park Trl , WA, Richland, WA, United States

    We have always assumed that the Columbia River and its tributaries have been the same for many millions of years. The Earth is constantly fooling us like that.  In reality most river systems are dynamic, and the Columbia River is no exception. We will explore how it has changed over the past 16 million years.  We’ll see how in earlier times locations such as like Yakima, Prosser and Benton City would have been on the Columbia River, while the Tri-Cities would have been left high and dry. The Columbia River system is one of the great river systems of North America, draining much of the Pacific Northwest, as well as parts of the western United States and British Columbia. The river system has had a long and complex history, slowly evolving over the past 17MY The Columbia River and its tributaries have been shaped by flood basalt volcanism, Cascade volcanism, regional tectonism, and finally outburst floods from Glacial Lake Missoula. The most complex part of river development has been in the northern part, the Columbia Basin, where the Columbia River and its tributaries were controlled by a subsiding Columbia Basin with subtle anticlinal ridges and synclinal valleys superimposed on a flood basalt landscape. After negotiating this landscape, the course to the Pacific Ocean led through the Cascade Range via the Columbia Trans-Arc Lowland, an ancient crustal weakness zone that separates Washington and Oregon. The peak of flood basalt volcanism obliterated the river paths, but as flood basalt volcanism waned, the rivers were able to establish courses within the growing fold belt. As the folds grew larger, the major pathways of the rivers moved toward the center of the Columbia Basin where subsidence was greatest. The finishing touches to the river system, however, were added during the Pleistocene by the Missoula floods, which caused local repositioning of river channels.
