SUMMARY:Mapping Dry Falls: A Bird’s-Eye View
DESCRIPTION:Join Wenatchee Valley Erratics for our Meeting on Tuesday\, October 13\, 6:30 Meet & Greet\, 7:00 Presentaion\, at the The Wells House: \nMapping Dry Falls: A Bird’s-Eye View of Washington’s Iconic Floodscape featuring Daniel Coe via Zoom. \nDry Falls is one of the Pacific Northwest’s most geologically significant landscapes. Its dramatic\, deeply eroded terrain preserves evidence of catastrophic glacial outburst floods on a scale that is almost impossible to imagine. \nIn 2025\, the Washington Geological Survey published an interpretive map which provides a bird’s eye view of the huge landforms at Dry Falls. \nDan will discuss how he and his colleague\, Dr. Joel Gombiner\, constructed this terrain-based map\, and will review the challenges in portraying and interpreting this vast landscape. He will also show several new lidar-based landform visualizations from around our state. \nDaniel Coe has been making maps of the Pacific Northwest for the past two decades. He is the graphics editor at the Washington Geological Survey in Olympia where his work explores the geomorphology and natural hazards of Washington State. \nWhen not making maps\, he is usually out enjoying the forests and waters of our region. You can see his work at dancoecarto.com \nDaniel Coe – Works for Washington State DNR and specializes in: Visual communication of geologic and geomorphic processes\, natural hazards\, and lidar-based landform visualization.\nClick here for more information about Daniel Coe \nThe presentation will be broadcast live at the The Wells House\,\n625 Nelson Ave\, Wenatchee\, WA 98801. \nIf you can’t make it to the Wells House\, no worries… Join Our Zoom Meeting Live October 13\, 2026\nhttps://us02web.zoom.us/j/81855547958\nMeeting ID: 818 5554 7958

SUMMARY:Cheney-Spokane Members Meeting and Public Lecture 2026
DESCRIPTION:This event is open to the public\, but only IAFI Cheney-Spokane members can vote during the member meeting. It will be held in the Liberty Lake area at the 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. \n\nSaltese Uplands Conservation Area hike: 12:00 PM – 1:30 PM\nShort Member meeting: 2:00-2:15 PM\nSpeaker: Glenn Cruickshank (a.k.a.\, Google Earth by Glenn) (beginning after the Member meeting)\n“Dating Erratics — an IAFI-funded project — the results!”\nSynopsis: The Spokane Chapter of the IAFI is partnering with a University of Massachusetts research team to locate and study glacial erratics near the Ice Age Floods breakout zone in North Idaho and eastern Washington. These boulders—stranded high on hillsides as the floods tore through the region—hold important clues about when and where the floodwaters moved. By determining the ages of these erratics\, researchers can better reconstruct the timing and pathways of the cataclysmic events that shaped our landscape.\n\nNote: At present\, we have openings on our chapter board.  Our board meets the second Tuesday of each month from 10 AM- 12 PM at the Cheney Depot 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 \nPlease 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. \nFor those coming on the hike\, please download and fill out this form for each participant\, and bring it with you to the trailhead. Liability form.

SUMMARY:Free 'Night Sky Over Cottonwood Canyon' Dark Skies Presentation and Night Telescope Viewing
DESCRIPTION:Night Sky Over Cottonwood Canyon\, a free presentation and night telescope viewing by Dark Skies leader and Gorge Chapter member Mike McKeag\, will be held at Cottonwood Canyon\, State Park (near Wasco\, Oregon) on Saturday\, Sept. 12\, beginning at 7:00 PM. \nThe evening will begin with a short presentation by park ranger\, Stan Petersen\, on light pollution\, followed by Mike’s presentation linking objects in that night’s sky with historical and geological events. Mike will describe the stages of twilight\, and then some of the night sky objects’ distances form us\, when the light we observe that night started on its way to us\, and their availability for observation as the sky darkens. \nHe’ll then relate that time to events in human or geological history\, such as the geological history exposed in the canyon walls. For more distant objects the events are geological. The last event is emplacement of the Grand Ronde basalts exposed in the canyon walls of Cottonwood Canyon (~16 mya)\, corresponding to the departure time of light from the spiral galaxy M94\, 16 M light years distant. \nThe presentations will end as we are entering nautical twilight and brighter stars are beginning to appear. Rose City Astronomers volunteers will be there with their telescopes\, sharing views of these and other objects available to view that night\, as well as pointing out several of the constellations that will be visible. \nThis event is free and open to the public\, with attendees of all ages welcome. Pre-registration\, however is required and free overnight tent camping will be available in the Day Use Area for this event. \nCottonwood Canyon State Park is a popular\, certified International Dark Sky Park with several hiking paths\, interesting geology\, birding and other flora and fauna. The park straddles the lower John Day River so there’s good fishing and a boat launch access at J.S. Burres just across the river. You can take advantage of this opportunity to explore an exceptional area. \n \nNote: Cottonwood Canyon State Park is remote. There is no food\, fuel or other services nearby. Please plan ahead thoughtfully for your trip. \nStar Party may be cancelled if bad weather or lack of volunteers with telescopes are not available.

SUMMARY:Spirit Lake Library Lecture II: The Ice Age Missoula floods and the Spirit Lake giant current dune field
DESCRIPTION:(This will be the same presentation as June 27.) Giant Current Dunes or MegaRipple Marks – One of the most important pieces of evidence for catastrophic flooding was the “giant current dunes.” These large-scale bedforms appeared as patterns of parallel ridges and swales on many aerial photographs in the flood channels in the scabland of Washington\, but had escaped recognition from the ground because of their size.  \nGiant Current Dunes are visible west of Clark Fork near Castle Rock; however\, the most prominent and visible Giant Current Dunes are located several miles east of Spirit Lake along Hwy 54 where the highway cuts through the dunes showing their undulating profile. The location of many of the telephone poles on the crest of these dunes accentuates these landforms. The dunes form transverse to the current direction\, and form cusps that are convex upstream\, with arms that point downstream. Furthermore\, the size of the cusps appears to decrease in the direction of lower velocity. Internally\, the dunes consist of gravel and pebble foresets. \nGiant current dunes exhibit an asymmetrical profile with the downstream (lee) slope steeper than the upstream slope. Crests range from 20 to 200m apart and heights range from 1 to 15m (Baker and Nummedal\, 1978) and are among the largest measured throughout the Floods area. The Spirit Lake current dunes can also be easily recognized from the air by their characteristic pattern\, accentuated by vegetation. This dune field is immediately in the path of the breakout from Lake Pend Oreille\, and experienced some of the highest energy flows. \nPresented by Dr. Linda McCollum\, president of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter \nNo registration required.

SUMMARY:Spirit Lake Library Lecture: The Ice Age Missoula floods and the Spirit Lake giant current dune field
DESCRIPTION:Giant Current Dunes or MegaRipple Marks – One of the most important pieces of evidence for catastrophic flooding was the “giant current dunes.” These large-scale bedforms appeared as patterns of parallel ridges and swales on many aerial photographs in the flood channels in the scabland of Washington\, but had escaped recognition from the ground because of their size.  \nGiant Current Dunes are visible west of Clark Fork near Castle Rock; however\, the most prominent and visible Giant Current Dunes are located several miles east of Spirit Lake along Hwy 54 where the highway cuts through the dunes showing their undulating profile. The location of many of the telephone poles on the crest of these dunes accentuates these landforms. The dunes form transverse to the current direction\, and form cusps that are convex upstream\, with arms that point downstream. Furthermore\, the size of the cusps appears to decrease in the direction of lower velocity. Internally\, the dunes consist of gravel and pebble foresets. \nGiant current dunes exhibit an asymmetrical profile with the downstream (lee) slope steeper than the upstream slope. Crests range from 20 to 200m apart and heights range from 1 to 15m (Baker and Nummedal\, 1978) and are among the largest measured throughout the Floods area. The Spirit Lake current dunes can also be easily recognized from the air by their characteristic pattern\, accentuated by vegetation. This dune field is immediately in the path of the breakout from Lake Pend Oreille\, and experienced some of the highest energy flows. \nPresented by Dr. Linda McCollum\, president of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter \nNo registration required.

SUMMARY:Post Falls Library Lecture: What Happened when the Dam Burst?
DESCRIPTION:Geologist Michael Hamilton talks about the geology of the Spokane area which reveals an interesting part of the glacial flood story. When the glacial ice dam failed\, the area immediately downstream received deposits of sediments and various landforms that provide clues of what happened when the dam burst. What we see in the flood deposits around Spokane also suggest insights on the sequence and size of the outburst floods. \nPresented by Michael Hamilton\, geologist and board member of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter \nNo registration required.

SUMMARY:Harrison Library Lecture: Introduction to the Ice Age Floods and the National Geologic Trail
DESCRIPTION:At the end of the last Ice Age an ice dam in northern Idaho created Glacial Lake Missoula stretching 3\,000 square miles around Missoula\, Montana. The dam burst and released flood waters across Washington\, down the Columbia River into Oregon before reaching the Pacific Ocean. The Ice Age Floods forever changed the lives and landscape of the Pacific Northwest. \nThe Ice Age Floods National Geologic Trail is a network of routes\, sites\, and interpretive centers that follow the pathways of the repeated Ice Age megafloods released from Glacial Lake Missoula between roughly 18\,000 and 15\,000 years ago. These floods reshaped the Pacific Northwest on a continental scale\, carving features such as the Channeled Scablands\, Grand Coulee\, Dry Falls\, Palouse Falls\, and the Columbia River Gorge. It spans four states—Montana\, Idaho\, Washington\, and Oregon—and links dozens of geologic landmarks that preserve evidence of these enormous floods. \nPresented by Don Chadbourne\, geologist and board member of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter \nNo registration required.

SUMMARY:Mysteries of the Channeled Scablands and the two Detectives who Solved it.
DESCRIPTION:Giant Pothole near Washtucna\, WA\nOver 100 years ago\, scientists discovered the unique landscape of the Channeled Scablands of Washington. By studying clues in Montana\, Idaho\, Washington\, and Oregon\, two of them pieced together the evidence that led to their conclusion which was scoffed at by many of their colleagues. After more than 20 years of field study and overwhelming evidence\, most of the scientific community finally agreed with them.  \nSee how today\, new detectives are in the field with new technologies to unravel more of the mysteries of the Channeled Scablands.  \nLloyd Stoess\, President of the Palouse Fall Chapter of the IAFI\, will show pictures and explain the evidence of the enormous Missoula Floods that carved our landscape.  \nThis will also be available on Zoom: Join Zoom Meeting\nhttps://us06web.zoom.us/j/89175830218 \nJoin instructions\nhttps://us06web.zoom.us/meetings/89175830218/invitations?signature=A-eaOzzCh1jy5rfktTN7oAoucFkSE0aKCWq9f_DNyAs

SUMMARY:Norwegian Scenic Routes - An Ice Age Floods Trail Model
DESCRIPTION:Interpreting Landscapes Of Deep Time: Norway’s Scenic Routes & The Ice Age Floods National Geologic Trail \nFor the past several years\, architect Rand Pinson has been researching and exploring the Ice Age Floods National Geologic Trail. That work led to a fellowship with the Architecture Foundation of Oregon and a trip to Norway to study its celebrated Scenic Routes program and National Parks\, where world-class architecture supported through infrastructure has transformed how people experience remote landscapes. \nWhile there he met with local architects and learn from their experiences designing rest stops\, bridges\, parking areas and lookouts for Norway’s “Scenic Routes” system of carefully selected roads that prioritize nature\, innovative architecture\, and art. He sees\, “Norway’s scenic route system as a compelling model. It’s a great way to integrate architecture and design into scenic settings.” He says\, “I’m interested in the idea of storytelling in architecture\, and this project presents an opportunity to shape a larger narrative that impacts the area.” \nIAF Norway Collage\n“One of the key challenges of the Ice Age Floods National Geologic Trail\,” he noted\, “is its lack of visibility and cohesive infrastructure. The exciting part of this project is finding the interesting ways history\, ecology and architecture intersect\,” he shared. “How can we take advantage of the site’s natural beauty\, promote it and expand its potential? The National Geologic Trail already features remarkable elements\, such as Maya Lin’s land art pieces that integrate seamlessly into nature. What it needs is a unifying vision to tie everything together. My goal is to contribute to growing tourism for this interesting and beautiful national park.” \nHe is using his Norway explorations along with travels along the Ice Age Floods National Geologic Trail and experiences derived from OSU’s Gorge Naturalist Program to compile research\, develop documentation\, drawings and models with the hope of one day bringing those ideas to life for our Trail. \nIn this presentation\, Rand shares his discoveries for the potential of the Ice Age Floods trail. Drawing on the intersections of geology\, history\, and design\, he will present a vision for how thoughtful architecture and interpretation could bring this extraordinary landscape the public presence it deserves. This FREE presentation is sponsored by the Columbia River Gorge Chapter of the Ice Age Floods Institute. \nThe presentation begins at 7:00 PM\, Thursday\, April 30\, in the Sprint/Baker Gallery Room of the White Salmon Valley Community Library\, 77 NE Wauna Ave\, White Salmon\, WA 98672. \nRand Pinson\nRand Pinson\, AIA\, is a partner and architect at Pine Bureau\, a narrative-driven architecture practice. Rand has extensive experience across the US landscape and is an alumnus of the world-renowned Auburn University Rural Studio in Hale County\, Alabama. His professional work includes design-build projects at the Epicenter\, a nonprofit community design center he helped found in Utah; Lake Flato Architects in Texas; and Waec hter Architecture in Portland\, Oregon\, focusing on residential\, environmental\, and hospitality projects. His work has won numerous AIA awards and has been featured in international publications and exhibitions\, including the Museum of Modern Art in New York and the Venice Biennale. Rand was named the 2025 Van Evera Bailey Fellow by the Architecture Foundation of Oregon.  Rand is a member of the Ice Age Floods Institute\, a Master Naturalist\, and a geology enthusiast. He is drawn to an architectural narrative that resonates in memory\, is responsive to the land and environment\, and is grounded to its time and place.

SUMMARY:Mega-Floods of the World - The Legacy of Dr. Bretz' Work
DESCRIPTION:Researchers have established\, based on the pioneering work of Dr. J Harlen Bretz and JT Pardee\, that over 140 Ancient Mega-Flood\, including Noah’s Flood are discussed in oral traditions worldwide. Professional geologist Bill Burgel will briefly discuss how the research related to the Missoula Floods and Bonneville Flood has opened up the possibility of mega-floods being the most likely explanation for the formation of the Mediterranean Sea\, the Persian Gulf\, The Bosphorus Straits\, the English Channel\, Chimu in Peru and the floodwaters on Mars. Mega-flood events are also being cited for the draining of Glacial Lake Agassiz\, Glacial Lake Iroquois and the Grand Canyon of the Yellowstone.

SUMMARY:Puget Lobe Lecture: Getting a Feel for Ice Sheet Hydrology and Channeled Scabland Geomorphology
DESCRIPTION:            Dr. Joel Gombiner\nJoel Gombiner\, Washington Geological Survey\, “Getting a feel for ice sheet hydrology + Channeled Scabland geomorphology” \nThis presentation connects modern observations of ice sheet hydrology\, the geomorphology of the Channeled Scabland\, and recent publications on Washington’s Ice Age floods. The presentation consists of three parts: (1) an explanation of a new lidar-based\, semi-realistic oblique visualization and interpretive poster of Dry Falls (released 2025 by WGS); (2) an intuitive overview of ice sheet hydrology with visits to Greenland\, Iceland\, and Antarctica; (3) an update on recent Channeled Scabland science including evidence for subglacial tunnel channel floods from the Okanogan lobe and refined estimates of Missoula flood magnitudes.  \nThe in-person meeting will be held at Bellevue College T building Room 118 on Monday\, March 2\, 2026 at 7:00 PM.\nThe live presentation will also be available on Zoom.

SUMMARY:Bill Burgel - Geology in the Growth of the Railroad Industry
DESCRIPTION:Bill Burgel will give a presentation on the Synergy between the development of the science of Geology with the growth of the railroad industry with a short description of how it impacted BNSF’s Cascade Tunnel’s ventilation system. \nThe advent of the Industrial Revolution accelerated the development of the science of geology\, and the growth of the railroad industry closely followed. A quick look at both of these disciplines over the past 200 years reveals a fascinating back and forth which resulted in amazing advances for both. \nFor instance\, geologists found the coal and then the railroads transported this coal to locations where people worked and lived. And coal mines virtually dictated where the rail line should be built. Comparisons between the two efforts continue to the present day and Bill will outline some of the current challenges. \n  \nIn 1995\, Bill was heavily involved in the installation of a new ventilation system for BNSF’s Cascade Tunnel. Ventilation of the tunnel has been an issue since the first Cascade Tunnel opened in 1900. Bill will describe how BNSF ensures safe operations in the current (second) Cascade Tunnel\, the longest railroad tunnel in the United States. \nBill Burgel is a Professional Geologist Registered in Oregon and Idaho. He retired in 2015 after a successful 45-year career in the railroad industry. He worked for several railroads nationwide in both the engineering and operating departments. While working for the railroad\, his interest and training in geology was often called upon to resolve landslide issues and rerouting studies\, implement early earthquake warning strategies\, and conduct numerous long railroad tunnel analyses. Bill has given numerous presentations on rail issues as well as earthquake preparedness and topics pertaining to regional geology to local audiences throughout the Pacific Northwest and on cruise ships.
