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.

Let Your Feet, and Your Imagination Roam at Rowena Crest and Tom McCall Preserve

Scenic Rowena Crest and the Tom McCall Preserve area provide an incredibly scenic place to let your feet, and your imagination wander as you look out on a major chokepoint along the Ice Age Floods path. The wildflower displays are amazing during the Spring, but several compelling flood-related features are visible from the vantage of the Rowena Crest Viewpoint any time of year. Rowena Crest lies nearly 700 feet above the Columbia River at the upstream end of the Rowena Plateau, a miles-long plateau that the river flows along. Just upriver from the plateau is the narrow section of the Gorge known as the Rowena Gap The drive to the viewpoint on old Hwy 30 from either east or west is a spectacular ride through a wonderous section of the Columbia River Gorge. A roundabout parking area at the viewpoint, with a safety wall above a sheer cliff, provides a great observation point eastward toward Rowena Gap. At Rowena Crest it’s easy to imagine what it might have been like to witness the approach of those massive floods. There is not yet scientific evidence that humans were in the area to bear witness to the Ice Age Floods, but there is solid evidence of humans in the Americas by that time. And there is growing concensus that if they came in during a glacial maximum, they would have come in by a coastal route that offered plentiful food and shelter for their journey. The mouth of the Columbia River would have been the first major waterway path inland that might have led them to settle in the area of the Floods. Your village might have been situated across the Columbia at the mouth of the Klickitat River where the town of Lyle now sits. If you were foraging, or just relaxing, atop Rowena Crest on a late summer day, you might have felt the ground begin to temble as if there were a small earthquake, but the trembling would have slowly increased for a few hours. Eventually you would have heard a low roaring sound that also grew over an hour or more before you could see turbulent brown muddy water begin flooding across the broad basin to the east. Then the roaring flood of water, only a few feet deep at first, would have entered the narrows, now called Rowena Gap, and sped on, crashing against the promontory you’re standing on and being diverted toward your village which was quickly washed away by the muddy torrent. But the muddy flood waters would have kept rising, unlike the Spring floods you’re used to on the Columbia, becoming a hundred feet deep, then two hundred as the levels just kept rising. Soon a huge whirlpool formed in the flood waters near the base of the promontory and a giant eddy formed where your village had been as flood waters flowed backward up the Klickitat River even as the bulk of the water continued downstream on the main stem of the Columbia. As the flood waters reached 400 and 500 feet deep and kept coming, suddenly to your right a huge block of the promontory broke off and slumped down into the rampaging flood waters. Now you would have begun running south toward higher ground, climbing higher and higher as the still rising flood waters poured across the plateau and plunged into the small creek valley to the west, tearing away at the valley walls and massively widening that little valley. Eventually the flood waters stopped chasing you upward as you climbed higher, 200 then 300 feet above the now submerged promontory. Now as you turned and looked out across that expanse of muddy water you could see massive white blocks of ice being carried along on the flood waters, similar but inconceiveably larger than the ice blocks carried on the river during the Spring floods. But the flood waters didn’t begin to recede that day, nor the next, as they might in the Spring floods. In fact it was almost half a lunar cycle before they began to slowly recede, exposing a mud coated Columbia River valley that was now noticably wider, with layers of shear vertical rock walls extending over 1000 feet above the normal river level below. As you began the recovery from the floods devastation, your family returned from from their hunting and gathering in the high mountain meadows, and you have an incredible story to pass along to them and your ancestors. This story is easy to imagine as you look out to the east from Rowena Crest. The onrushing Ice Age Floods waters easily flowed over the low relief of the broad Dalles Basin to the east, but the major Rowena Gap created a chokepoint in the path of the floods as they made their way through the Columbia River Gorge. This “hydraulic dam” forced the flood waters to build to over 1000 feet deep in this area, flowing hundreds of feet deep over Rowena Crest while forming a temporary lake in The Dalles basin. It is estimated that many of the 40-100 Ice Age Floods may have taken up to a month to completely flush through the system to the Pacific Ocean, but the duration of the flood waters at any point along the path probably lasted less than a couple of weeks. But this was more than enough to create several major floods features visible from this vantage point. At Columbia River level below and east of the promontory is a round Kolk pond that was created by giant whirlpools in the flood waters as they were deflected around the Rowena Crest promontory. Other similar Kolk features can also be seen on the Dallesport area to the east, and along the hiking path atop Rowena Crest where they are marked by surrounding groves of oak trees. grew Across the Columbia, the floods deposited a huge eddy gravel bar that the entire town of Lyle, Washington is built upon. The Klickitat River was backed up for miles
Mima/Desert/Biscuit Mounds – An (Possible) Explanation

If you’ve visited the Rowena Crest Viewpoint at Tom McCall Preserve, west of The Dalles in the Columbia River Gorge, you may have noticed the many dome-shaped earthen mounds that cover the Rowena Plateau. These mounds are broadly circular and are surrounded by collections of basalt rock fragments. If you’ve visited the spring wildflower mecca of Catherine Creek on the Washington side of the Gorge, you may have also wondered at what caused the stripes of black rock extending down the slopes above the area. Tens of thousands of similar soil mounds cover large areas of the high desert lands of north-central Oregon, often in swarms that number in the hundreds. These mounds can be round or elongated, can range from a dozen feet to more than 60 feet in diameter atop the rocky Columbia River Basalt bedrock, and are typically surrounded and separated from each other by rings or stripes of basalt rock fragments. The mounds also appear similar to those at Mima Mounds Natural Area Preserve near Olympia, WA. There have been many suggested causes for the creation of these mounds, from burial mounds, to Pleistocene pocket gophers, to plants or glacial sun cups trapping wind-blown sediment, to sorting by earthquake vibrations, to turbulence at the base of ice-age floods flowing over the landscape. Research by two Oregon graduate students, Clark Nelson of Oregon State University and John Baine Pyrch of Portland State University, independently came up with what may be the most likely explanation for the origins of these enigmatic features. Their theses suggest desert mounds and their rock rings formed through a process of natural sorting, where fine soil material is pushed up into mounds and associated rocks are pushed out to the edges to form rings through countless cycles of wetting/drying and freeze/thaw during the wetter and colder period of the late Pleistocene. Clark Nelson cut a trench through a mound that exposed layers of soil and volcanic ash whose lack of mixing discounts the pocket gopher theory. Nelson also found that slope angle less than or greater than 10 degrees determined whether the features would form rounded mounds vs. elongated stripes. Pyrch showed the strips to be distinct from common talus slopes, because no obvious source of rock exists at the head of the talus stripe. He also observed that rocks within these stripes are sorted, unlike talus slopes, suggesting the same ice age freeze-thaw origins as soil mounds and rock rings. You can read more detailed articles about these enigmatic features in these articles: Mystery of the Desert Mounds Great Pyramids of the Gophers: Mima Mound Mystery Solved Similar processes are also thought to be responsible for the “patterned ground” found in periglacial environs. However these various types of features may have formed, we can be certain how the few mounds in the center of the parking circle at Rowena Crest Viewpoint came to be. They were man-made during the construction of the viewpoint and made to look like the mounds that cover the Rowena Plateau. At least one origin has a definitive answer.

Lyle Cherry Orchard Trail Geology Recording

The Lyle Cherry Orchard Trail is a moderately strenuous trail being developed in the Columbia Gorge by Friends of the Columbia Gorge. They envisioned having a number of interpretive stations along the trail to inform and educate trail users. A station could focus on a single topic, such as the geology, plants, animals, indigenous and cultural history of the area. But they found that the cost of interpretive signs would be prohibitive, would be expensive to maintain and might not last long. So they started brainstorming for better ways to realize thier vision. The came up with a plan to place trailside posts, resembling basalt columns, with a QR code the user could scan with their smartphone that would connect to an informative recording about that location. Friends hopes to have the trail work and information stations finished by 2024. Then everyone will be able to experience the beauty along the Lyle Cherry Orchard Trail with a deeper understanding of their surrounding through the recordings. Renee Tkach, a Friends coordinator of the project, contacted Lloyd DeKay, president of the IAFI Columbia Gorge Chapter, about doing a recording for the first station about the geology of the area. They took a very windy hike together on the still somewhat challenging trail to the first station, where they talked about the focus of a recording and took a number of photos to document the views. At home Lloyd developed a script that everyone reviewed and agreed upon. Then began a few frustrating hours of recording and editing to produce a 4:30 minute recording. Since the original plan was for a 3:00-3:30 minute recording, Friends will now review the recording and decide if it’s OK or needs to be shorter and where to cut back. This method may also be an easier, economical and useful way to provide information at other floods sites throughout the region. Significant advantages include the relatively low cost and long life of the information station, and ability to provide both video and audio clips for a number of features on a webpage linked to the QR code, and the ability to modify and update the presentations as new or updated information becomes available.
Explore the Columbia River Gorge

The Columbia River Gorge is an incredibly popular area to visit, and that’s for good reason, the setting is uniquely spectacular. The Gorge encompasses: Easily accessible ecozones that range through boreal conifer forests, oak woodlands, high desert grasslands and alpine environments in only 40 miles, Dazzling viewpoints and scenery, including beautiful waterfalls that cascade over the high basalt ramparts that bound the relatively narrow Gorge and the majestic Columbia River running through it, Mt. Adams, Mt. St. Helens and Mt. Hood, imposing snow-covered stratovolcanoes lying less than 40 miles north and south of the Gorge, Picturesque small towns that are bounded by extensive federally- and state-protected natural areas throughout the length of the Gorge, Abundant recreation opportunities including hiking, road/mountain biking, windsurfing and kiteboarding, whitewater kayaking and rafting, fishing, hunting, alpine/cross-country skiing and snowshoeing, Numerous award-winning wineries and breweries, restaurants and pubs, shops, galleries, museums, parks, hotels and campgrounds, And all this is lying at the back doorstep of Portland, Oregon. The Gorge is also a geologic wonderland, exposing stories about: The 40 million year history of the Columbia River, The series of massive Columbia River Basalt flows 18-12 million years ago, The rise of the Cascade Mountain Range since about 5 million years ago, The passage of numerous, up to 1000 feet deep Ice Age Floods that reshaped the Gorge 18-14 thousand years ago, Tectonic faulting and folding, landslides, earthquakes, forest fires, and The often intertwined lives and stories of the people who have lived here. Of course, with all this bounty the area is also a robust tourist mecca, which can mean limited accommodations for summer crowds. Most attractions are easy to drive to, but bus tours and river cruises are also available. Due to the popularity, some of the iconic attractions now seasonally restrict vehicle access and require permits.
Exploring the Geology of the Gorge with Wildwood Academy

Wildwood Academy, a small alternate school in Hood River, Oregon, contacted the IAFI Columbia River Gorge Chapter with a request for a Gorge Geology presentation for their younger and older student groups. On a couple of days in November, as chapter president, I talked to the two groups from a slideshow covering the last 40+ million years of Columbia River Gorge geology, followed up by short field trips to local sites of geologic interest. As you might imagine, making an hour-long, semi-technical presentation to school kids can be a daunting experience. But these kids were tuned in, attentive, and incredibly responsive, with questions and comments that were right on target. Of course, their teachers had already touched on many elements of Gorge geology, so the kids said they felt the show’s progression through time helped bring it all together for them. And their energy in the classroom and in the field was a wonder to behold. The free-ranging atmosphere at this alternate school was eye-opening and exciting, especially for someone who grew up many years ago in a more structured public school atmosphere. But possibly more important is the feeling that the wonder and excitement of learning and experiencing the world around are alive and well in all the generations following my 75 years. Of special importance to me was a note from one of the parents, “My daughter was one of the kids you spoke to today and she has done nothing but talk about how amazing you were and how she wants to study the Columbia River Gorge area. I have heard nothing else since about 4 o’clock this afternoon!!” It’s a thrill and a real honor to have had that kind of impact.
