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.

Mapping the Glacial Legacy of the Pacific Northwest

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

Glaciers have shaped much of the Pacific Northwest’s landscape over the past 15,000 years. Geologists and cartographers have been mapping and interpreting glacial landforms since the late 19th century. And now LIDAR helps create incredibly accurate, detailed, and stunning maps.

Course Changes of Inland NW Rivers Due to the Ice Age Floods

Connell Library 118 N. Columbia, Connell, Washington

Lloyd Stoess will present a free lecture with information showing how the Columbia, Palouse, and Yakima Rivers all had course changes during the last glacial period of the Ice Age. All three were changed by different forces. One was temporary and the other two were permanent. This lecture is in partnership with the Mid-Columbia Libraries Connell branch.

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

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

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.

New Interpretations of Old Strandlines

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.
