UNESCO International Geodiversity Day – Oct. 6th

The International Geodiversity Day was established today by the 41st session of the UNESCO General Conference!! From now on, the 6th of October will be an annual worldwide celebration, raising awareness across society about the importance of non-living nature for the well-being and prosperity of all living beings on the planet! The winner of the competition for the International Geodiversity Day logo, Silas Samuel dos Santos Costa, is a student at Universidade Federal do Rio Grande do Norte (Natal, Brazil) and produced the attached logo that can be freely used in all initiatives related with the International Geodiversity Day. Congratulations Silas! The success of this initiative was in no small part due to the breadth of international and national organizations that endorsed the proposal. In particular the support of both IUGS and the Permanent Delegation to UNESCO from Portugal played an essential role in submitted the proposal. The website geodiversityday.org is the virtual focal point for all information regarding this International Day. New social media feeds were launched that you can use to stay updated with plans for International Geodiversity Day: facebook.com/GeodiversityDay twitter.com/GeodiversityDay

The Case for Rapid and Recent Flooding in Upper Grand Coulee

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

On 07 Oct 2024 the Puget Lobe Chapter will have Dr. Karin Lehnigk, Postdoctoral Researcher at Georgia Tech, who has studied the Channel Scablands in Eastern Washington by performing cosmogenic nuclide exposure dating on Missoula flood   transported-boulders to determine what path they took at different points in time.  It will be a very informative lecture with new information.  Think Mars and Himalayan Mountains. Cosmogenic nuclide dating is a method used to estimate the age of rock exposure at the Earth’s surface. It relies on the interactions between cosmic rays and nuclides in glacially transported boulders or eroded bedrock. By measuring nuclide concentrations, scientists can determine the age of landforms ranging from a few hundred years to tens of millions of years.  It looks like a crust or rind on surface of the sample when you cut or break a sample open.

“Mega-Floods” – Presentation by Bill Burgel

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

Bill Burgel In a field of geological investigation first identified and then pioneered by J Harlen Bretz, JT Pardee and Vic Baker, Mega-Floods have been recognized throughout the world and on the planet Mars. These catastrophic floods are quite capable of sculpting the landscape wherever they occur with disastrous consequences. Can they happen today? What are some notable historic examples? Is Noah's Flood one of these events? How are they different from Mega-Tsunamis that are also found around the globe? Bill will answer these questions and more at the October 24th meeting of the Lower Columbia Chapter of the Ice Age Institute. Thursday, October 24, 2024, In Person 6:45PM PDT at the Tualatin Heritage Center, 8700 SW Sweek Drive, Tualatin, OR 97062 ALSO Simultaneous Live ZOOM from THC if you cannot attend the THC meeting in-person.

Cheney-Spokane Chapter Fishtrap Lake Scablands Hike

Fishtrap Lake South Loop

Fishtrap Lake, Washington (BLM Photo) Come join us for a 5-mile hike to explore the Ice Age floods features in the Fishtrap Lake area east of Sprague, WA! The Cheney-Spokane Chapter of the IAFI is scheduling a hike at the south loop trailhead of Fishtrap Lake on Saturday, October 26th . The hike will start at 10:00 a.m. The hike will be led by Don Chadbourne, geologist and board member of the Cheney-Spokane Chapter. You will meet the leader at the trailhead. Description of Fishtrap Lake Hike The hike will begin and end at the south trailhead at Fishtrap Lake. The hike will follow the south loop trail, with a total length of about 5.5 miles. The trail is mostly single track over dirt and rock, with an elevation gain and loss of about 500 feet. The hike will provide an intimate view of the channeled scablands that were carved out by the ice age floods. Features will include pothole lakes, rock benches, mima mounds, kolks, and streamlined and scarped Palouse hills. The hike will also provide wide open views of Fishtrap Lake and the surrounding country. This hike is included in On the Trail of the Ice Age Floods – Northern Reaches, by Bjornstad & Kiver. However, we will be following trails that were constructed after the book was published. Directions to the trailhead From I-90 take Exit 254 and proceed south 3.6 miles on the Sprague Highway. Turn left (east) on Miller Ranch Road and proceed 0.2 miles to the “T” at the Miller Ranch house. Turn right(south) and drive 0.8 miles to the trailhead parking lot.

Mammoths of Coyote Canyon

Zoom Meeting

On Nov11, 2024, Join the Ice Age Floods Chapter Puget Lobe for a look at the Coyote Canyon (Mammoth) dig site: This site was originally discovered in 1999; but left undisturbed until 2008, with formal excavation beginning in September,2010.  The accompanied photo shows the work done thru Jun 2014.  In the intervening 10+ years additional work has completed.  As you can see by the photograph, the cinder block, 5-gal bucket, and the4x4 lumber bream, this may be a small portion of the overall site. The presentation will be Zoom only and given by IAFI Vice President Mr. Gary Kleinknecht.  Meeting starts at 7:00pm with sign-ins  starting  at 6:45. click on Zoom link:   https://us02web.Zoom.us/j/82985244730 Working Site as of June 2012

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.

Geology Alive: Understanding Geologic Hazards in the Columbia Gorge

Columbia Center For the Arts 215 Cascade Ave, Hood River, OR, United States

The great scenic beauty of the Gorge owes much to the geological processes that have shaped it.  Earthquakes, volcanic eruptions, landslides and debris flows still occur in the area today, and they can pose hazards to Gorge residents and visitors.  What is the scope, severity, and likelihood of these hazards?  How do scientists use evidence from the geological and historical past to evaluate the hazards, and how do they use models to forecast future hazards and inform our efforts to prepare for them? Join Dr. Richard “Dick” Iverson, Scientist Emeritus at the U.S. Geological Survey’s Cascades Volcano Observatory, as he digs into the geological hazards of the Gorge—and explains why they don’t discourage him from living here! GET TICKETS HERE When: NOVEMBER 13th, 2024 | Doors 6pm, Show 7 pm Where: Columbia Center For the Arts, 215 Cascade Ave, Hood River, OR This event will be livestreamed on our Givebutter page: https://givebutter.com/geologyalive Doors open at 6 pm, show starts at 7 pm. * We encourage people to take their seats by 6:45. * Seats not filled by 6:45 will be made available to our waitlist. * Event tickets are non-refundable. Richard (Dick) Iverson spent 34 years as a research scientist at the U.S. Geological Survey’s Cascades Volcano Observatory in Vancouver, Wash., and he remains affiliated with the observatory as a scientist emeritus. His work there has focused mostly on the dynamics of landslides, debris flows, and volcanic eruptions, with particular emphasis on evaluating hazards downstream from Cascades volcanoes.  Iverson grew up in Iowa, received his Ph.D. from Stanford University, and moved from Vancouver to Hood River in 2018.
