    Cheney-Spokane Members Meeting and Public Lecture by Dr. Eugene Kiver

    October 5, 2024 @ 2:00 pm - 5:00 pm PDT
    Doris Morrison Learning Center (DMLC) 1330 S Henry Road, Greenacres, Washington

    This event is open to the public, but only IAFI Cheney-Spokane members can vote during the member meeting. It will be held at the beautiful new Doris Morrison Learning Center at 1330 S. Henry Road.  Exit the freeway south on Barker Road, turn left at the roundabout at Sprague Road, then right at the three-way junction on Henry Road. Member meeting: 2:00-3:00 PM Dr. Kiver's lecture will begin around 3 PM, after the member meeting.  It is open to the public (see title and blurb below). Note: At present, we have three openings on our chapter board.  Our board meets the third Tuesday of each month from 3-5 PM at the Wren-Pierson Building in Cheney.  Interested? Members with expertise in accounting or K-12 education or medical experience or any other expertise that would aid our chapter's mission should send a very brief vita to Dr. Linda McCollum, President, IAFI Cheney-Spokane Chapter, lmccollum@ewu.edu   Dr. Eugene Kiver Lecture: GLACIERS AND MISSOULA FLOODS IN NORTHEASTERN WASHINGTON Immense quantities of Glacial Lake Missoula floodwater roared through not only the Rathdrum/Spokane floodway but also through the rugged mountain topography of the Northern Rockies in northeastern Washington. Here floods ripped across non-basaltic glaciated rocks and through the Little Spokane River drainage into the Channeled Scabland south of the present course of the Spokane River. This alternate route is often overlooked. The Pend Oreille River course north of Newport has been reversed and now flows north into Canada. Glacial suppression of the crust is the suspected culprit. Over a mile of ice buried the Pend Oreille River valley near Canada during the late Wisconsin ice advance allowing water to flow north and cut deep canyons along the river course.

    The Case for Rapid and Recent Flooding in Upper Grand Coulee

    October 7, 2024 @ 7:00 pm - 8:30 pm PDT
    Bellevue College Building T Room 127 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.

    New Interpretations of Old Strandlines

    January 29, 2025 @ 7:00 pm - 8:00 pm MST
    Montana Natural History Center 120 Hickory Street, Missoula, MT

    It’s that time of the year! Time to contemplate ice ages and glacial lakes. Time for the Glacial Lake Missoula Chapter of the Ice Age Floods Institute’s Cabin Fever Lecture!  Warm up your curiosity about those iconic strandlines we can see from town with a lecture from renowned geologist James W. Sears. New “LiDAR ” mapping techniques may imply that the famous Lake Missoula strandlines on Mount Sentinel and Mount Jumbo record only one draining of the ice-age lake. The draining coincided with massive erosion at the bottom of the lake, but passive lowering of lake level at the top, marked by short-term strandlines cut a few inches into thin colluvial soil on the mountainsides. About the Instructor: Dr. James W. Sears received his PhD from Queen’s University, Canada, in 1979, and has taught at the University of Montana since 1982. This is a live event that will not be recorded or streamed.

It is of moderate difficulty and consists of a dirt and rock trail with switchbacks, spanning about 700 vertical feet. Bring your own snacks & drinks, good hiking shoes, and dress appropriately for mid October weather conditions. Lunch is not provided. Meet the hike leader at the Saltese Flats Wetland trailhead at 11 AM.) Member meeting: 2:00-3:00 PM Speaker: USGS Geologist Jim O'Connor (beginning after the Member meeting) "A Century of Discovery: 102 Years of Studying the Ice Age Spokane Flood" Synopsis: For more than a century, geologists have investigated the massive Ice Age floods that swept through Spokane, reshaping the region’s terrain and sparking global scientific interest. USGS Geologist Jim O'Connor will review some of the discoveries made in our understanding of these cataclysmic events—from their origins and pathways to the dramatic landforms they left behind. He will also highlight some of the enduring questions that continue to drive new research, revealing how much there is still to learn about one of North America's most extraordinary geological phenomena. Note: At present, we have three openings on our chapter board.  Our board meets the third Tuesday of each month from 3-5 PM at the Wren-Pierson Building in Cheney.  Interested?

    Puget Lobe Lecture: Jeff Tepper on the Initiation of the Cascade Arc

    November 17, 2025 @ 7:00 pm - 8:30 pm PST
    Bellevue College Building T Room 127 3000 Landerholm Cir SE, Bellevue, WA, United States

                    Dr. Jeff Tepper The Cascade volcanic chain, the world’s youngest continental arc, was “born” shortly after accretion of the  Siletzia oceanic terrane ~50 My ago.   That collision, which led to formation of the Olympics, terminated the  earlier subduction system and caused a portion of the subducting Farallon slab to break off.  When Cascade  magmatism began less than 5 My later, there was a new trench located outboard of Siletzia.  In this talk I will  present a new model, based on petrology, geochronology, plate motion reconstructions, and mantle tomography,  that explains how subduction was initiated so quickly and in a setting where the slab was young and hot and in  theory too buoyant to subduct.

    Puget Lobe Lecture: The Bonneville flood- the other flood!

    January 5 @ 7:00 pm - 8:30 pm PST
    Bellevue College Building T Room 127 3000 Landerholm Cir SE, Bellevue, WA, United States

    The Bonneville Flood was one of the largest floods on Earth. First discovered by G.K. Gilbert in the 1870s during his inspection of the outlet at Red Rock Pass, Idaho, it was rediscovered in the 1950s by Harold Malde and coworkers, leading to mapping and assessment of spectacular flood features along Marsh Creek, Portneuf River, and Snake River for over 1100 kilometers between the outlet and Lewiston, Idaho. The cataclysmic flood - from the rapid 115-meter drop of pluvial Lake Bonneville from the Bonneville level to the Provo level - was nearly 200 meters deep in places and flowed at a maximum rate of about 1 million cubic meters per second — about 100 times greater than any historical Snake River flood. Along its route the Bonneville Flood carved canyons and cataract complexes and built massive boulder bars. These flood features have been a rich source for understanding megaflood processes. Yet it still offers much more with new and developing techniques for hydrodynamic modeling and landscape analysis.
