Quincy Basin Field Trip

Othello Lions Park 815 East Fir Street, Othello

During the Missoula Floods the Quincy Basin was filled with flood waters mostly arriving through Grand Coulee and the Telford-Crab Creek Scabland Tract via Crab Creek. Some spillover from the Cheney-Palouse Scabland Tract also entered the basin through east-west coulees.  The flood water drained out of the basin in four places that will be visited on this car Caravan Tour - Crater/Lynch Coulee, Potholes Coulee, Frenchman Coulee, and Drumheller Channels. Stops are also planned for Moses Lake, the Ephrata Fan, Soap Lake, Lower Moses Coulee, West Bar, and Babcock Bench. FIELD TRIP REGISTRATION FORM   LIABILITY RELEASE FORM

DMLC-2 Saltese Flats Spokane Valley

Cheney-Spokane Members Meeting and Public Lecture

Doris Morrison Learning Center (DMLC) 1330 S Henry Road, Greenacres

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. Saltese Uplands Conservation Area hike: 11:00 AM - 1:00 PM (Note: A completed liability form is required for this 3-mile hike. 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? 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 Please use the button below to sign up for the event and optional hike. Your registration helps us plan more smoothly and ensure a great experience for everyone.

Stephen Angster

Northern Kittitas Valley Fault Trace Research – Postponed

Hal Holmes Community Center 201 Ruby St, Ellensburg

Stephen Angster, +one Our speaker, Steven Angster, scheduled for October 11th is going to have to be rescheduled as he is a federal employee with the USGS and is not allowed to do any work related activities during the shutdown.     We are tentatively looking at a new date in late June of 2026.  We are still working on the details of that. Stephen Angster, a research scientist at the Seattle Field Office of the U.S. Geological Survey’s Earthquake Science Center, focuses on characterizing and integrating upper-plate fault source parameters for probabilistic seismic hazard analysis in the Pacific Northwest. He employs a multidisciplinary approach—emphasizing paleoseismic trenching as a tool alongside geophysical and geological investigations—to better understand the spatial and temporal patterns of prehistoric large earthquakes. Doors will open at 3:30 pm with the presentations beginning at 4:00pm. This event will offer an opportunity to browse and purchase such Ice Age Floods items as books, maps, posters and baseball caps. All purchases must be with cash or check only please. Steve currently leads active research projects on both sides of the Cascades. On the west side, he has identified new fault scarps along the Seattle fault zone and the Canyon River fault. East of the Cascades, his work focuses on constraining the nature and extent of back-arc deformation. Understanding strain accommodation across the Kittitas Valley is a key component to that research. He will present new data from studying several strands of a fault trace that spans many kilometers of the northern Kittitas Valley. Stephen holds a B.S. from Western Illinois University, an M.S. from the Colorado School of Mines, and a Ph.D. from the University of Nevada, Reno.
