Unearthing the Secrets of Spokane Valley: A Recap of the IAFI June Jamboree
This year’s IAFI June Jamboree delved into the fascinating geological history of Spokane Valley, contrasting it with the iconic Grand Coulee and Dry Falls, explored during last year’s Jubilee. Challenging the Landscape: Unlike the open spaces of Dry Falls, Spokane Valley presented a unique challenge – showcasing evidence of Ice Age Floods within an urban environment. Our chapter tackled this brilliantly, organizing hikes and car caravans departing from convenient public parks and commercial areas. Evening Explorations: The program’s highlights included captivating lectures. Professor Emeritus Dean Kiefer shed light on J Harlen Bretz’s Spokane associates, while renowned naturalist Jack Nesbit brought the story of the first Columbian Mammoth discovered near Latah Creek in the 1800s to life. Celebrating Success: The Jamboree culminated in a relaxed gathering at Mirabeau Meadows. Registrants, leaders, and participants exchanged insights and experiences, with a resounding appreciation for the chapter’s efforts. Comparisons were drawn, highlighting how our Spokane Valley exploration continued the excellence of the Puget Lobe’s outing at Dry Falls last year. A Delicious Finale: The grand finale was a catered Longhorn Barbecue overflowing with delicious food. Everyone left satisfied, with many even taking home doggie bags to savor the flavors afterward. Check out more images from the event in this Google Photo Album. Meet the Masterminds: Linda & Mike McCollum: This dynamic professor emerita and a research geologist duo co-led tours and car caravans, sharing their latest research on the Spokane area’s Ice Age Floods, and shaping the Jamboree’s theme. Michael Hamilton: A gifted geologist, Michael led hikes and the bus trip, encouraging questions and offering honest answers. Don Chadbourne & Chris Sheeran: Don, the chapter treasurer, managed logistics with expertise, while Chris, our media and registration guru, ensured a smooth experience. Melanie Bell Gibbs: A past president and national board member, Melanie oversaw participant check-in and badge distribution. Dick Jensen: Dick handled bus transportation and provided crucial support throughout the Jamboree. Jim Fox: The chapter vice president secured speakers and offered his assistance wherever needed. We also owe a great deal to the participant volunteers who proved invaluable in assisting us in all our efforts. Through the combined efforts of many the IAFI June Jamboree was a resounding success, fostering exploration, education, and a deeper appreciation for the Spokane Valley’s unique geological heritage. Being present with so much information and conversation among such extensive expertise was to witness the scientific process in action. Meeting people from other chapters was particularly nice, putting faces with names we know. We all learned a lot.
Scabland – The Movie, A Google Earth Odyssey
“Scabland” – the Movie, A Google Earth Odyssey “Scabland” is a media complement to CWU Professor Nick Zentner’s 2023-2024 A-Z YouTube geology series that re-treads the ice age floods and the work of Professor J Harlen Bretz and others. In this short animation, viewers virtually fly to a selection of locations visited by geologist Dr J Harlen Bretz, with quotes from his original field notes, geolocated in Google Earth and animated with Google Earth Studio. To see more of these locations, visit https://www.geology.cwu.edu/facstaff/nick/gBRETZ/ This video was done as an experiment/prototype by the authors, Glenn Cruickshank and Eric Larson, to showcase Google Earth, virtual special effects techniques, some of the spectacular landforms caused by the floods, the impacts of ice and water during the Last Glacial Maximum and the field locations of J Harlen Bretz.

Tualatin: Crossroads of the Ice Age Floods
Tualatin, Oregon, lies in its own valley near the head of the Willamette Valley. In the time of the Ice Age floods, about 18,000 years ago, the area was a rich wetland. The gift those floods left behind was a hearty silt containing loess that was picked up from lands in Eastern Washington in the rush of the flood waters. The depositied loess supported abundant plant life that supported the megafauna animals that benefitted from this rich land, including Columbian Mammoths, Mastodons, Giant Sloths, Grey Wolves, the first Horses, Bison and others in the Pleistocene Age. In today’s world, fossil hunting for these extinct animals is a fruitful treasure hunt and celebrated in the Tualatin area. Tualatin has helped lead the way in displaying Ice Age fossils at various family friendly sites in the City: Tualatin Public Library: Enter, and the first thing you see is the Mastodon skeleton displayed high behind the checkout desk framed in an etched glass panel depicting the grassland and the Mastodon’s body. This fossil skeleton was discovered nearby during a site excavation for a large retail store. Further on into the Library are a group of lighted display cabinets for fossils arranged on shelves. The cabinets are arranged side by side in a gentle arc for easy family viewing. 18878 SW Martinazzi, Tualatin, 97062. Tualatin Greenway: To the right and behind the Library/City Building is the entrance to the Tualatin Greenway, a trail system along the Tualatin River. It is complete with signage concerning Ice Age Floods. The primary trail is a long winding concrete path with a blue meandering mosaic center strip representing Tualatin’s part of the National Ice Age Trail. It’s a favorite for joggers, cyclists and those who love to walk. Cabela’s Shopping Center: Return from the Greenway to the front of the shopping center building. See the full-size juvenile Mastodon sculpture being admired by a farm boy holding a spade with which to find a fossil skeleton. At his farm, a molar tooth is a barn doorstop. Read the story on the plaque. Brian Keith is the sculptor. Inside Cabela’s store, see the Cave at the back which shows Ice Age fossils displayed in context. Tualatin Heritage Center: Here, Columbian Mammoth and Mastodon tusks are featured among other Ice Age fossils. Of special interest are the large granite boulder erratics on display outside, all with explanatory plaques. 8700 SW Sweek Dr., Tualatin, Oregon 97062 In addition, the Lower Columbia Chapter of the Ice Age Floods Institute offers regular presentations about various Ice Age Floods topics by renowned experts, as well as newsletters and other events of interest.

Traveling the Ice Age Floods National Geologic Trail
In September 2021 my wife and I took a trip to see what was new along the Ice Age Floods National Geologic Trail and visit some places we did not make it to in our very first trip in 2004. The IAFI chapter brochures were very helpful in learning what there was to see in each area. We also remembered a preview of the National Parks Service unigrid map brochure that will come out hopefully later this year, so be sure and get one when it debuts. The other excellent tool was the online interactive map on the Ice Age Floods Institute website (https://iafi.org/floodscapes/), where you can click on a spot and see a photo and description of the site. All are great planning tools. We drove to Missoula, Montana and stayed there a couple of days as we made day trips. Our first one was to Ovando to see a granite glacial erratic that the Glacial Lake Missoula Chapter had etched and placed at the high-water line. You will find it at Trixi’s Antler Saloon which is a nice place to grab a bite for lunch. The chapter has a number of these high water markers placed already and have more planned to show the full extent of Glacial Lake Missoula. Unfortunately, due to the smoke from the wildfires we were not able to go to Hamilton to see the 8-ton granite erratics outside Ravaili Museum with four interpretive signs outside and additional displays inside. We drove up to the Paradise Center in Paradise, Montana. We had been there before in 2016 for the fall IAFI field trip and they were just dreaming of what the old Paradise Elementary School could become. They have done a wonderful job of making that dream come true. It was one of our favorite spots on this trip. They have dedicated an entire room to the Ice Age Floods story where an extremely accurate 3-D map of Glacial Lake Missoula has lights installed so you can push a button to light up the edge of the ice lobe and other features. Besides information about the Ice Age Floods, the Center also has wonderful displays about the trains & train yard that used to be in Paradise and the history of the Paradise Elementary School. We went to the Natural History Museum in Missoula and enjoyed the panels and video which told the Lake Missoula Floods story and also about Joseph Pardee, a very important pioneer in solving the mystery of these Floods. This museum also displays an amazing amount of taxidermy showing the wildlife and birds in the region. On our way up to Sandpoint, Idaho we passed through Eddy Narrows. Glacial Lake Missoula drained through this canyon going 80 mph leaving horizontal marks high up on the walls. Previously these were thought to be glacial striations, but Pardee speculated that these marks were from huge boulders as they shot through the Narrows. The Narrows is long with few places you can pull over on Highway 200, so it can be hard to really appreciate its scope. We got a good view from the Koo-Koo-Sint Bighorn Sheep Viewing Interpretive Site which has several interpretive signs that talk about the sheep and the geology of the Clark Fork River Valley. We then went over to Farragut State Park at the southern tip of Lake Pend Oreille to view the beginning of the outburst plain that formed the Rathdrum/Spokane Valley aquifer. Across Lake Pend Oreille is Green Monarch Ridge; the terminus of the Purcell Trench which held the 4,000 ft. ice dam that carved the steep walls. The display at the museum has several interpretive panels. The next day we met Consuelo Larrabee who gave us a personal tour of the 40,000 square foot Ice Age Floods Playground in Riverfront Park in Spokane, Washington. She and Melanie Bell, the president of the Cheney-Spokane chapter, did an enormous amount of work as consultants on this fabulous, themed park. Kids can learn as they play on the three-story Columbian slide tower, Glacial Dam splash pad, log jam climber, an alluvial deposit fossil dig, and more. The park was filled with kids and the adults were enjoying it as much as the kids. We loved watching the excitement of a child as she saw the splash pad water fountains simulate the ice dam starting to rupture and then the cascade of water flooding over the manmade basalt rocks. Along the side of the building are actual basalt columns and the fossil dig led to many exciting discoveries by the children as they dug through the sand to reveal embedded replicas of fossils. Throughout the park are thoughtfully placed benches for people to sit and watch the fun going on around them. There are nine interpretive panels throughout the park adding a wonderful educational benefit to all the fun. This park will be quite a prize for years to come. The next day we drove along Highway 262 to W. McManamon Road to the Drumheller Channels National Natural Landmark. This outlet from the Quincy Basin, with floodwaters going 65 mph eroded not just the topsoil but the underlying basalt which created dramatic channels, basins, potholes and buttes. The viewpoints along the drive had several interpretive panels talking about these wonderful vistas. Since we live in Portland and this trip was to see places we had not recently seen, we skipped over the many wonderful places in the Columbia River Gorge, Willamette Valley & Tualatin. But for your trip, please check out the hundreds of beautiful and interesting sites to see in this region. The last stop for this trip was Cape Disappointment. The Floods debris flushing out the mouth of the Columbia River added substantially to submarine Astoria Fan and sediment cores have shown that ocean currents carried some of this debris all the way down to Cape Mendocino, California. Although not visible from the surface, the Park display has a relief map that shows the Astoria Canyon
Ice Age Floods Institute at GSA Convention
In August the Ice Age Floods Institute was offered an opportunity to share an exhibitor booth with the Tualatin Ice Age Floods Foundation (TIAFF) at a major geological conference, the October 10-13 Geological Society of America (GSA) Convention in Portland, OR. This gave IAFI an opportunity to present the Floods Story and educate a worldwide assemblage of geological professionals, researchers, and students, many of whom were not even aware of the Floods or their immense scope. The IAFI Board jumped at this opportunity, approving the registration cost and putting the booth development in the hands of the Columbia River Gorge Chapter President and IAFI Webmaster, Lloyd DeKay, aided by IAFI Membership Secretary, Sylvia Thompson, who also represented TIAFF along with Dr. Scott Burns of Portland State University. With Dr. Burns influence, we were able to acquire a corner booth space very near the main GSA area that ensured a good parade of participant traffic past our booth. We used 3D modeling software to design the booth to scale, then began assembling the materials for the booth. We used QGIS software, with assistance from Stacy Warren of Eastern Washington University, to develop a new map that highlighted the Floods paths, various glacial and temporary lakes along the floods path, as well as the final resting place of much of the sediment eroded by the Floods on the Astoria Submarine Fan. We then printed the map and other images, purchased, trimmed and covered 2” foam insulation boards for display walls, borrowed tables, made table covers, and gathered IAFI Store materials for sale. The day of reckoning came Oct. 8th, when we moved everything to the Oregon Convention Center and set it all up. The Exhibit Hall opened at 5:00pm and we began telling the story that would repeat many times over the next 4 days to people from around the world. We talked with relative locals (WA, OR, ID, MT, NV and CA), people from other parts of the US (at least AK, AZ, UT, CO, TX, AR, IA, KS, KY, IL, MN, WI, LA, GA, NC, SC, AL, FL, NJ, NY, MA, NH, VT, RI, CT), and several countries (including Canada, Finland, Holland, UK, Italy, Morocco, Zimbabwe, India, China, Australia, Columbia, Mexico, and Costa Rica). In all, there were 2,700 in-person participants this year. Our booth was one of the most popular and usually had 2-5 people at a time looking at the displays. Geologic luminaries such as Vic Baker, Richard Waitt, Scott Burns, Bruce Bjornstad and Nick Zentner also stopped by, attracting even more visitors to the booth. We gave away National Park Service, IAFI and TIAFF brochures and we sold books, maps, hats and t-shirts as well as our packets of chapter brochures. Though it involved a lot of time and work for the members and volunteers who manned the booth, we feel it was well worth the effort to educate and spread the Story of the Ice Age Floods. Many thanks to IAFI members Lloyd DeKay, Sylvia and Rick Thompson, and TIAFF volunteers Jerianne Thompson, Yvonne Addington and Linda Moholt for helping make this effort a stunning success. And we now have materials and experience that will serve well for future professional, educational and general public events like this.
”Global Megaflood Science” Dr. Vic Baker
“Global Megaflood Science” – Dr. Victor R. Baker – Lower Columbia Chapter -Virtual Meeting Starting in the late 1960s, an accelerating pace of discovery has revealed that the last major de-glaciation of planet Earth involved a global pattern of huge outbursts of water from the margins of wasting continental ice sheets. Much of this water was delivered as relatively short-duration floods with peak flows comparable to those of ocean currents. The global inventory of these phenomena now includes about 4 dozen examples from Asia, Europe, North America, South America, and Iceland. Though there have been many advances in understanding the physical processes and geochronology of megaflooding, important controversies remain, including: the role of flooding on areas that are now under the oceans; the nature of subglacial megaflooding; and the details of the vast network of megaflood landscape features in Asia. Immense outburst floods likely induced very rapid, short-term effects on the global Earth environment. Recorded Thursday, July 16, 2020 at 7:00 PM

Use Social Distancing Time to Explore the Floods with Our Interactive Online Map
If you’ve ever tried to explore the Ice-Age Floods with a guidebook you’ll know how difficult and frustrating it can be to find and learn about the features in the area you’re visiting. Well, there’s now a solution to that problem; an interactive map that’s available wherever you have internet access. The map features over 300 points of interest throughout our 4-state area, with a description and images that slide out when you click on one of the markers. More features are being added all the time, and we’re planning to expand the map with features related to the Lake Bonneville Flood event that rampaged through the area during the time of the Ice-Age Floods. Since this is an internet-based map, it’s also easy to get driving directions to the site from wherever you are starting from. You can also easily build an informative field trip, exploring and learning about a number of other nearby features with just a few clicks of your mouse. We feel this may be the most useful field guide ever developed to explore ice-age Floods and glacial features throughout our 4-state region. AND it’s absolutely FREE! The only shortcomings we see are 1) the map requires internet access, which isn’t always available in far-flung areas of our region, and 2) we may not have every point-of-interest on the map (YET!). If we’re missing something you think is important we encourage you to submit your suggestion. We also appreciate any comments and/or corrections by email to Webmaster@IAFI.org. We sincerely hope you enjoy using this guide to poke around these fascinating ice-age features.
