Missoula Floods Feature – A Site of Mammoth Proportions
It has been well proven that the Missoula Floods greatly impacted central Washington and there are many examples of the magnitude of the floods, its reach, and dynamics. However, there is still debate on the number, size and timing and dating of these events. What is also less well known are some of the casualties of the floods. At least one feature is helping to tell the story of some of the last floods to grace the landscape. In 2015, a mammoth was discovered at Tonnemaker Hill Farm along the north edge of the Frenchman Hills in Grant County, Washington. Luke Tonnemaker was plowing up an alfalfa field when he made the discovery. Intensive study of the site was led by geologist George Last, paleontologist Bax Barton, local soil scientist and geologist Mark Amara, Gary Kleinknecht, education director, from the MCBONES Research Foundation, a volunteer excavation crew from MCBONES and the Tonnemaker family. The researchers coordinated with farm co-owners, Luke and his father, Kole Tonnemaker, and their wives Amanda and Sonia respectively, to professionally excavate, stabilize retrieved mammoth bones, identify as many bones as possible, and recreate the geology and history of the site. Mammoth remains are not that uncommon in Washington with several hundred animals discovered in the state, though fewer than 100 of those discoveries are located in eastern Washington. What is significant about this mammoth site is that it is one of the few finds that has received this much intensive study. Over 130 bones and bone fragments from a single Columbia mammoth were recovered with about 69 specimens identified. The animal was estimated to be between 25-30 years of age based on characteristics of its dentition, and it even lived with a damaged rib which had healed. George Last prepared diagram The presence of three distinct volcanic ash (tephra) layers and soil analyses suggests that at least four different Missoula flood event episodes are represented in the sediments beneath the mammoth bone bed. Dating of the site revealed that the animal post-dated identified Mount St Helens tephra eruptions that deposited ash in distinct horizons below the bones in water borne deposits. Dates associated with ash samples identified at WSU confirmed two of the layers correspond to Mount St. Helens S series while the topmost tephra shows some compositional variability but had similarities to the J or S series. Tephra ages ranged roughly from 14,000-16.000 years ago. Further dating through Utah State University was provided by optically stimulated luminescence (OSL) samples which gave dates ranging from 16-19,000 years ago. Since the bones are above the highest tephra and OSL sampling sites, the find is definitely younger than 16,000 years ago and was on the edge of one of last Pleistocene Missoula floods slack water lakes to cover this part of Washington. These conclusions were corroborated by analyzing the stratigraphy of the site and describing the soil which confirmed environments of deposition. Since the bones were above the aforementioned tephra layers and OSL sampling locations, and are at the interface of apparent windblown silts and Missoula floods slackwater deposits, it is still unclear how and when the animal died. However, the co-location of the mammoth remains with apparent ice-rafted erratic cobbles and boulders in fine-grained Missoula flood sediments, supports interpretation that the mammoth could have been carried in and left behind by a late breaking Missoula flood. Alternatively, it could have become mired in the mud along the shoreline and/or was killed by predators or even died in a subsequent drier period. Still the intensive studies to date have shown that this is an area with unique geologic history, one that is still unfolding. The Tonnemaker family has the recovered bones on display at their farm store and annually, including 2026, hold tours of the mammoth site during the Othello Sandhill Crane Festival held in March each year. There are a variety of papers, poster presentations and articles published or defended at meetings held by the Northwest Scientific Association and Geological Society of America, and a final report of findings between 2016-2024, with summaries highlighted, is available for viewing at the farm.

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.

Grand Coulee Area Hikes Report
Gene Kiver and Bruce Bjornstad led two hikes in the Grand Coulee area. A group of ~30 hikers joined in a moderately difficult hike into the Castle Lake Basin, part of a 4-mile wide cataract complex that extends all the way to Dry Falls. The hike started out near Coulee City by following the Main Canal, which delivers all water from the Columbia Basin Irrigation Project into two siphons that cross Don Paul Draw at the head of Deep Lake. From here the water disappears before flowing two miles, underground, through a pair of tunnels to Trail Lake Coulee. The hike continued by crossing a berm of basalt boulders, dug out for the Main Canal, into the Castle Lake Basin. A descent to the floor of the basin was possible via two steel ladders that crossed the cataract above the Castle Lake plunge pool. From there hikers traversed out to a potholed bench to a spectacular view above Deep Lake Coulee. The next day ~20 hikers joined a ~3 mile roundtrip hike to Giant Cave Arch, near Barker Canyon, along the west side of Upper Grand Coulee. For anyone interested, both these hikes are featured in “On the Trail of the Ice Age Floods: The Northern Reaches” a geologic guidebook published by Bjornstad and Kiver in 2012.
