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.

SUMMARY:Mystery of the Channeled Scablands and the Two Detectives who Solved it.
DESCRIPTION:    The unique landscape of the Channeled Scablands was a mystery that baffled the first geologists who visited them over 100 years ago. Finding clues\, they unraveled the mystery that was unbelievable to their colleagues. After more than two decades of discovering more clues\, the theory that enormous floods had carved the scabland was finally accepted by most of the scientific community.  \nLloyd Stoess\, President of the Palouse Falls Chapter\, will take you on a journey following these two early detectives and the clues they found as well as what today’s detectives and the modern tools they are using to better understand our incredible landscape.

SUMMARY:Puget Lobe Lecture: Jeff Tepper on the Initiation of the Cascade Arc
DESCRIPTION:  \n  \n            Dr. Jeff Tepper\nThe Cascade volcanic chain\, the world’s youngest continental arc\, was “born” shortly after accretion of the  Siletzia oceanic terrane ~50 My ago.   That collision\, which led to formation of the Olympics\, terminated the  earlier subduction system and caused a portion of the subducting Farallon slab to break off.  When Cascade  magmatism began less than 5 My later\, there was a new trench located outboard of Siletzia.  In this talk I will  present a new model\, based on petrology\, geochronology\, plate motion reconstructions\, and mantle tomography\,  that explains how subduction was initiated so quickly and in a setting where the slab was young and hot and in  theory too buoyant to subduct.  \n

SUMMARY:EVOLUTION OF THE COLUMBIA RIVER SYSTEM
DESCRIPTION:We have always assumed that the Columbia River and its tributaries have been the same for many millions of years. The Earth is constantly fooling us like that.  In reality most river systems are dynamic\, and the Columbia River is no exception. We will explore how it has changed over the past 16 million years.  We’ll see how in earlier times locations such as like Yakima\, Prosser and Benton City would have been on the Columbia River\, while the Tri-Cities would have been left high and dry. \nThe Columbia River system is one of the great river systems of North America\, draining much of the Pacific Northwest\, as well as parts of the western United States and British Columbia. The river system has had a long and complex history\, slowly evolving over the past 17MY The Columbia River and its tributaries have been shaped by flood basalt volcanism\, Cascade volcanism\, regional tectonism\, and finally outburst floods from Glacial Lake Missoula. The most complex part of river development has been in the northern part\, the Columbia Basin\, where the Columbia River and its tributaries were controlled by a subsiding Columbia Basin with subtle anticlinal ridges and synclinal valleys superimposed on a flood basalt landscape. After negotiating this landscape\, the course to the Pacific Ocean led through the Cascade Range via the Columbia Trans-Arc Lowland\, an ancient crustal weakness zone that separates Washington and Oregon. The peak of flood basalt volcanism obliterated the river paths\, but as flood basalt volcanism waned\, the rivers were able to establish courses within the growing fold belt. As the folds grew larger\, the major pathways of the rivers moved toward the center of the Columbia Basin where subsidence was greatest. The finishing touches to the river system\, however\, were added during the Pleistocene by the Missoula floods\, which caused local repositioning of river channels.

SUMMARY:Expansion of Early Roads in the US West
DESCRIPTION:On Tuesday October 14\, Dr. E. F. Cater\, Director of the Douglas County Historical Museum in Waterville\, will present a talk\, “Expansion of Early Roads in the US West.” The program starts at 7:00 PM\, at the Wenatchee Valley Museum and Cultural Center\, 127 South Mission\, in Wenatchee. Zoom link for those who cannot attend in person: https://us02web.zoom.us/j/8185554795 Meeting ID: 818 5554 7958 \nWestern roads developed by push and shove. Business people and shippers built some of the first usable roads. They needed to get wares to market. Others built ways to get to town to buy those goods. \nBuilding new roads\, and connecting roads\, was difficult and expensive. No entity wanted to do that. Not the Federal government\, nor the states\, not the counties. They got pushed into road-building. What happened? \nAround 1912\, the introduction of the automobile\, especially the Model T\, spurred the United States into building auto-routes adequate for travel. There were no transcontinental highways. Many states didn’t even connect with one another. \nLocally\, the Yellowstone Trail eventually passed through Waterville\, Wenatchee\, Monitor\, Cashmere\, and over Blewett Pass. We will learn about that road. \nClick the link below to see the first 3 minutes of the presentation:\nhttps://youtu.be/Htov6YXW6L8?si=ixgoJkN63zfs1mWi \nThe program is free and open to the public. \nSwitchbacks on Blewett Pass\, 1910

SUMMARY:Northern Kittitas Valley Fault Trace Research - Postponed
DESCRIPTION:Stephen Angster\, +one\nOur 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.     \nWe are tentatively looking at a new date in late June of 2026.  We are still working on the details of that. \nStephen 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. \nDoors 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.  \nSteve 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. \nStephen 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.

SUMMARY:Joseph Pardee - Swiss Army Knife for the USGS! w/ Bill Burgel
DESCRIPTION:Joseph T. Pardee\nBill Burgel will be speaking on the career and contributions of Joseph Pardee to our understanding of the Ice Age Floods. Joseph T. Pardee was a USGS Field Geologist who\, for 32 years (1910-1941)\, focused on a variety of geologic issues throughout the country. His geologic acumen was vigorously sought after by nearly every department within the USGS. \nPardee is most widely known for quipping that “he knew where Bretz’ water was.” As retirement approached\, Pardee used his intense observational skills and his incredible patience to finally devote himself to his secret love of Glacial Lake Missoula (GLM)when he published his “Unusual Currents.” It made clear that GLM drained catastrophically fast and flowed at incredible speeds. He thus provided a possible source for the catastrophic flood that Bretz had been postulating. \nDoors 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. \nBill Burgel\, Professional Geologist Registered in Oregon and Idaho\, retired in 2015 after a successful 45-year career in the railroad industry.

SUMMARY:How Do They Know? Major Findings About the Ice Age Floods
DESCRIPTION:  \nMaps\nHave you ever been watching a science program and wondered “How do they know that?” Dr. Gary L. Ford\, President\, IAFI\, will briefly discuss the how and who “figured it out” regarding aspects of the Ice Age Floods\, looking at five questions. These include: \n\nhow we know there was a huge glacial lake in western Montana thousands of years ago\,\nhow we know it drained rapidly perhaps a hundred times\,\nabout how many floods there were and when they occurred\,\nwhere the floodwater came from\, and\nabout how long it took the floodwater to get to the ocean.\n\nWe also go over which answers to these questions are still being debated by researchers. \nPresented in partnership with Ice Age Floods Institute (IAFI)

SUMMARY:How the Ice Age Floods Changed the Course of the Palouse River
DESCRIPTION:Palouse Falls – Photo Glenn Traver\nBefore the Ice Age Floods\, the Palouse River would have flowed through present day Washtucna\, Kahlotus\, Connell\, Mesa\, and Eltopia before entering the Columbia River near the Pasco Airport. Today\, it takes a fifty-mile shortcut to the Snake River at Lyons Ferry via the Palouse Canyon and Palouse Falls. \nIn this presentation by Lloyd Stoess\, President\, Palouse Falls Chapter\, IAFI\, we look at the two factors that caused this dramatic shift—either one by itself would not have been enough. To examine when this happened\, we look at some possibilities and clues recently discovered by scientists. \nPresented in partnership with Ice Age Floods Institute (IAFI) \n(Registration required on SCLD website. Registration opens at 6:30 PM Monday\, March 31\, 2025.)

SUMMARY:Tom Pierson - Geology of the Gorge
DESCRIPTION:Tom Pierson\, retired USGS Geologist/Hydrologist\, will present an overview of the catastrophic forces and events that have shaped the Columbia Gorge that we know today.  Our majestic ancient river has fended off unceasing\, violent geologic attempts to block it and divert it\, but it keeps on flowing–it’s quite a story. Tom will describe how small and huge volcanic eruptions\, colossal floods\, enormous landslides\, and the grinding forces of tectonic crustal deformation have all taken their shots\, yet the Columbia still flows to the sea. If you know where to look\, you can see the evidence of these old heavyweight knockout rounds.   \nThis talk will be hosted by the Columbia River Gorge Chapter of Ice Age Floods Institute at the White Salmon Community Library\, beginning at 5:30pm on Monday\, April 28.

SUMMARY:Mapping the Pacific Northwest's Glacial Legacy
DESCRIPTION:Enhanced LIDAR images (WA-DNR)\nGlaciers have shaped much of the Pacific Northwest’s landscape over the past 15\,000 years. The Cordilleran ice sheet\, repeated ice age floods\, and expansive alpine glaciation have left their distinctive fingerprints on the topography of our region. \nGeologists and cartographers have been mapping and interpreting glacial landforms since the late 19th century. In the past decade\, the Washington Geological Survey has created new maps that build upon this rich cartographic history by fusing older datasets and techniques with modern insights and technology\, such as lidar. \nUsing both historical and modern maps\, this presentation by Daniel Coe\, Washington Geologic Survey\, Seattle\, will be a visual journey through the Pacific Northwest’s glacial past and present. \nPresented in partnership with Ice Age Floods Institute (IAFI) \nThis event will be live via Zoom. Watch at the library or from anywhere you have an internet connection. Register in-person at the library to view the online presentation at Cheney Library. Register online to view the online presentation from home or anywhere. \nNote: as of April 2 at 9 PM there are still 33 in-person seats available and 93 online seats available! \nRegistration is required.

SUMMARY:Othello Sandhill Crane Festival
DESCRIPTION:The 27th annual Othello Sandhill Crane Festival – March 21\, 22\, and 23! Founded in 1998\, the Othello Sandhill Crane Festival highlights the spring return of Sandhill Cranes to the greater Othello area and the Columbia National Wildlife Refuge. Not only are there bird lectures and tours on all three days\, but the Festival always incorporates many geology talks; and field trips into Flood Country. Please see the events brochure here: https://www.othellosandhillcranefestival.org/_files/ugd/00304c_e3ceea5f94c44279af5e6e7a1cd036d7.pdf?index=true \nGeneral admission is $10 and covers lectures and activities at the School and Church. All other tours and activities priced as noted in the schedule along with general admission. \n \nFriday Night Featured Lecture – Bruce Bjornstad – The Grand Coulee Nowhere is the evidence for Ice Age Megafloods so dramatic and awe-inspiring than Grand Coulee. The evolution of Grand Coulee will be presented via a unique bird’s eye view of this unique 50-mile-long canyon. Evidence for dozens of megafloods through Grand Coulee\, as recently as 15\,000 years ago\, will be examined. This Lecture is free to attend in the Red Room at 7 PM.\n \nSaturday\, March 22 there will be several talks on geology at the Crane Festival.. \nIce Age Floodscapes. Bruce Bjornstad tells of an appreciation of the huge scale of Ice Age Megafloods and the features they left behind are often hidden and lost at close range. An aerial perspective of dozens of different unique flood features will be presented to bring the immense power and magnitude of the Ice Age Floods into focus \nCoulees\, Canyons\, and Valleys\, Oh My! Lloyd Stoess will present a somewhat tongue-in-cheek look at how scientists can’t always agree on the definition of landforms\, like coulees. Coulees interlace the landscape of\nthe channeled scablands of eastern Washington which were carved by the Ice Age Floods\, but what really defines them and how do they differ from canyons and valleys? \nCoyote Canyon: A Mammoth Burial in Ice Age Floods Sediments. Gary Kleinknecht will introduce the audience to Columbian Mammoths\, North America’s elephant. He will present evidence for the assertion that this specimen is buried in slack water deposits left by a series of huge floods which created temporary Lake Lewis in the southern Columbia Basin. The discovery of mammoth bones\, the on-going excavation of the site\, and the paleoenvironmental study at Coyote Canyon will also be discussed. \nSunday\, March 23\, Geology Field Trips \nMega Floods Through Wild Drumheller Channels Hike\, 9:00 AM to 3:00 PM. $60.00. This moderately difficult 3-4-mile hike\, led by geologist Bruce Bjornstad\, will directly explore the flood channels (including the former path of the Columbia River)\, potholes\, erratic\, and streamlined basalt islands\nrimmed with towering 50’ basalt columns. One hundred years ago\, J Harlen Bretz recognized this area as one of the most spectacular examples of Ice Age Flood erosion in the Channeled Scabland. Note that there will be no restrooms available on this hike. Bagged lunches are available for order on the registration form. This tour is six hours in length\, so bring food\, drink\, and sturdy walking shoes. \nSONY DSC\nThe Great Escape of Quincy Basin\, 8:00 AM to 4:00 PM. $60.00. Join Lloyd Stoess and Ken Lacy on a tour to showcase some of the most impressive floodscape that they have ever shown. It will focus on the impact of flood waters escaping the Quincy Basin. Imagine 150 feet of water dropping 800 feet in less than 3 miles\, we will see this at the Potholes Coulee. We will also visit places with particularly dramatic views in the Drumheller Channels\, Frenchman Coulee\, West Bar\, and the Ephrata Fan. There will be no hikes but open-toed shoes will not be appropriate. There will be bathroom breaks along the way. This tour is about 8 hours from start to fin

SUMMARY:Take a Bee-Line to the Wild Side
DESCRIPTION:Wild bees are a diverse group of bees that are important pollinators for many crops and plants. The U.S. has roughly 4\,000 species of wild bees that pollinate thousands of plants\, including many common foods like apples and almonds. Wild bees\, along with many pollinators\, are declining around the world due to land changes\, human activities\, pesticide use\, and other threats. Despite growing concern about population declines\, there are limited data about wild bees. You can help wild bees by providing nesting boxes\, restoring pollinator-friendly habitats\, and encouraging legislation that protects bees. In his “Take a Walk on the Wild Side” presentation\, Steve Castagnoli will provide an introduction to the natural history of wild bees in the Pacific Northwest.  \n \nSteve Castagnoli is an apprentice level melittologist with the Oregon Bee Atlas. The Oregon Bee Atlas Master Melittologist Program trains and equips citizen scientists to: a) create and maintain a comprehensive and publicly accessible inventory of the state’s native bees and their plant-host preferences\, b) to educate Oregonians on the state’s bee biodiversity and c) to conduct an on-going survey of native bee populations in order to assess their health. Specimen records are added annually to newly digitized historic records from the Oregon State Arthropod Collection to build the first comprehensive account of the native bee fauna of Oregon. \n \n

SUMMARY:The Ancient Ice Age Floods in the Pacific Northwest
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday\, February 11 at 7:00 PM. Our speaker will present remotely via Zoom from Portland. Those not computer- or Zoom-savvy can attend in-person for a live screening at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. Or at home using Zoom link    https://us02web.zoom.us/j/81855547958  Meeting ID: 818 5554 7958 \nDr. Scott Burns\, Professor Emeritus of Geology at Portland State University\, is a researcher\, teacher\, and story-teller of Pacific Northwest Geology. He will discuss “The Ancient Ice Age Floods in the Pacific Northwest.” \nWe know that Ice Age Floods have inundated the Pacific Northwest over the past 2.8 million years. But we primarily concentrate on the last ones\, the Missoula Floods\, that occurred between 20\,000-15\,000 years ago. That’s because the Missoula Floods left the most visible record; they obliterated nearly all the evidence of earlier inundations. Current research\, however\,  shows an unfolding story of the many torrents that preceded the Missoula Floods. Erica Medley\, an MS student of Dr. Burns\, discovered many deposits of these rarely discussed ancient floods. Dr. Burns\, a most dynamic speaker\, is here to talk about those older ones! \nThe program is free and open to the public.

SUMMARY:New Interpretations of Old Strandlines
DESCRIPTION:It’s that time of the year! Time to contemplate ice ages and glacial lakes. Time for the Glacial Lake Missoula Chapter of the Ice Age Floods Institute’s Cabin Fever Lecture!  Warm up your curiosity about those iconic strandlines we can see from town with a lecture from renowned geologist James W. Sears. \nNew “LiDAR ” mapping techniques may imply that the famous Lake Missoula strandlines on Mount Sentinel and Mount Jumbo record only one draining of the ice-age lake. The draining coincided with massive erosion at the bottom of the lake\, but passive lowering of lake level at the top\, marked by short-term strandlines cut a few inches into thin colluvial soil on the mountainsides. \nAbout the Instructor: Dr. James W. Sears received his PhD from Queen’s University\, Canada\, in 1979\, and has taught at the University of Montana since 1982. \nThis is a live event that will not be recorded or streamed.

SUMMARY:Richard B. Waitt - The "Debacle Which Swept the Columbia Plateau" 100 years on
DESCRIPTION:J Harlan Bretz\n“It was a debacle\,” wrote J Harlan Bretz in 1923\, that carved Washington’s Channeled Scabland. This prescient finale today brings to mind debacles geologic\, personal and periodic. \nThe cataclysm in Bretz’s “Spokane flood” initiated a famous controversy. Published arguments against great Scabland flood erupted in the 1920’s and raged on into the 1940’s–critics by various more conventional schemes calling for less water over more time. As Bretz had almost no published support\, it seemed to many his personal debacle. Yet re-reading the early reports\, and recently the summary field notes\, I sense that by the extraordinary field evidence he had documented throughout the region\, Bretz knew all along that his ‘catastrophysm’ would prevail. After J.T. Pardee showed in 1942 that huge glacial Lake Missoula had discharged abruptly. Bretz and colleagues in 1956 show with the old evidence–and with stark new evidence in giant current dunes adorning many gravel bars–that water from glacial Lake Missoula had indeed carved the ‘Channelled Scabland’. With detailed geomorphic field evidence they skewer Bretz’s critics–this in turn becoming their personal debacle. \nwaittThe story takes a more gradualistic turn with discovery that Lake Missoula drained periodically. In his final Scablands paper in 1969\, Bretz\, by geomorphic evidence counts seven floods at most. But hardly a decade later\, new stratigraphic evidence was showing that Lake Missoula released scores of giant floods during the last glaciation alone. These outbursts were both periodic and gigantic by degrees\, truly colossal and coming decades apart when the damming Purcell Trench lobe was thick\, but as the ice gradually thinned diminishing to coming only a decade or a few years apart\, and at the end one year apart. This ‘jokulhlaups’ idea erupted new controversy\, this one also lasting more than two decades. If it has simmered down lately\, this argument is also being settled by field evidence. \nIf Missoula floods were numerous and periodic during last-glacial marine-Isotope stage 2 (25-15 thousand years ago)\, what happened during seemingly equally deep glaciations of AR-isotope stages such as 6 and 12 (140-440 thousand years ago)? So far we know of no supporting field evidence–only scattered field sites that suggest one gigantic flood far back\, perhaps a million years ago. It will be for today’s young scientists to decipher this and other remaining enigmas. \nThursday\, January 16\, 2025\, In Person 6:45PM PST\nTualatin Heritage Center\, 8700 SW Sweek Drive\, Tualatin\, OR 97062\nALSO Simultaneous Live ZOOM from THC if you cannot attend the in-person THC meeting yourself.\nClick here for Zoom meeting\, Meeting ID: 869 4651 3479 Passcode: 322382.

SUMMARY:Geology Alive: Understanding Geologic Hazards in the Columbia Gorge
DESCRIPTION:The great scenic beauty of the Gorge owes much to the geological processes that have shaped it.  Earthquakes\, volcanic eruptions\, landslides and debris flows still occur in the area today\, and they can pose hazards to Gorge residents and visitors.  What is the scope\, severity\, and likelihood of these hazards?  How do scientists use evidence from the geological and historical past to evaluate the hazards\, and how do they use models to forecast future hazards and inform our efforts to prepare for them? \nJoin Dr. Richard “Dick” Iverson\, Scientist Emeritus at the U.S. Geological Survey’s Cascades Volcano Observatory\, as he digs into the geological hazards of the Gorge—and explains why they don’t discourage him from living here! \nGET TICKETS HERE\nWhen: NOVEMBER 13th\, 2024 | Doors 6pm\, Show 7 pm\nWhere: Columbia Center For the Arts\, 215 Cascade Ave\, Hood River\, OR\nThis event will be livestreamed on our Givebutter page: https://givebutter.com/geologyalive\nDoors open at 6 pm\, show starts at 7 pm. * We encourage people to take their seats by 6:45. * Seats not filled by 6:45 will be made available to our waitlist. * Event tickets are non-refundable. \n\nRichard (Dick) Iverson spent 34 years as a research scientist at the U.S. Geological Survey’s Cascades Volcano Observatory in Vancouver\, Wash.\, and he remains affiliated with the observatory as a scientist emeritus. His work there has focused mostly on the dynamics of landslides\, debris flows\, and volcanic eruptions\, with particular emphasis on evaluating hazards downstream from Cascades volcanoes.  Iverson grew up in Iowa\, received his Ph.D. from Stanford University\, and moved from Vancouver to Hood River in 2018. \n
