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) URL:https://iafi.org/event/how-do-they-know-major-findings-about-the-ice-age-floods/ LOCATION:Spokane Valley Library\, 22 N Herald Rd\, A\, Spokane Valley\, W\, WA\, 99206\, United States CATEGORIES:Cheney-Spokane,Presentation ATTACH;FMTTYPE=image/jpeg:https://iafi.org/wp-content/uploads/Gary-Ford-erratic-Crop.jpg ORGANIZER;CN="Cheney-Spokane Chapter":MAILTO:iaficheneyspokane@gmail.com END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250505T190000 DTEND;TZID=America/Los_Angeles:20250505T203000 DTSTAMP:20260403T112331 CREATED:20241222T020244Z LAST-MODIFIED:20250430T184302Z UID:39276-1746471600-1746477000@iafi.org SUMMARY:1.5 Million Years of Climate Data from the Antarctic Drilling Project DESCRIPTION:(05Dec2024) The Mid-Pleistocene Transition (MPT)\, where the Pleistocene glacial cycles changed from 41 to ∼100 kyr periodicity\, is one of the most intriguing unsolved issues in the field of paleoclimatology. Jerry McManus is an AGU Fellow who is Chair of Columbia University’s Environmental School. He spent time in Antarctica as part in a European-led consortium project to drill down an existing drill hole to punch back another half-million years of climate data from ice in the Antarctic Ice Sheet. The goal of the project was to get a continuous ice record reaching back past the Mid Pleistocene Transition (MPT) to get a better perspective on the short cycle into the long cycle transition. At our May meeting\, Jerry will present an early glimpse on what the team discovered.  The May 05 meeting will be held in Bellevue College\, Room B104.  The program begins at 7:00 PM.

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.

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.

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.

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.

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  URL:https://iafi.org/event/take-a-bee-line-to-the-wild-side/ LOCATION:White Salmon Valley Community Library\, 77 NE Wauna Ave\, White Salmon\, WA\, 98672\, United States CATEGORIES:Presentation ATTACH;FMTTYPE=image/jpeg:https://iafi.org/wp-content/uploads/Oregon-Bee-Project.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250218T184500 DTEND;TZID=America/Los_Angeles:20250218T193000 DTSTAMP:20260403T112331 CREATED:20250205T224630Z LAST-MODIFIED:20250205T224630Z UID:39745-1739904300-1739907000@iafi.org SUMMARY:Oregon Gold - This valuable mineral is brought to you by Geology DESCRIPTION:Geologist and professor\, Sheila Alfsen\, will show how geologic processes that occurred in Oregon paved the way for the discovery and utilization of gold in our state.

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.

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.

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.

It’s a day to remember the Earth’s incredible history and to pay tribute to the amazing geologists who help us understand it. We’ve been dependent on rocks since we first walked the Earth\, and today it’s no different\, with rocks forming the foundation of our daily lives. \n \n \nHistory of “Old Rock Day”\nThe study of rocks was first introduced by the Ancient Greek Theophrastus in his work\, “Peri Lithon” (“On Stones”)\, and became the cornerstone of geology for other interested scientists. The study was advanced by Pliny the Elder\, who recorded numerous minerals and metals in great detail\, with a particular focus on their practical use. Although working without the tools we use today\, Pliny was able to correctly identify the origin of amber as fossilized tree resin. \nIt wasn’t until 1603 when the word ‘geology’ was used for the first time by Italian naturalist Ulisse Aldrovandi. It took a further 150 years for the first geological maps to be drawn by British geologist William Smith\, whose work began the process of ordering rock layers by examining the fossils contained in them. \nThen\, in 1785\, James Hutton wrote and presented a paper to the Royal Society of Edinburgh called ‘Theory of the Earth’\, which outlined his belief that the world was far older than previously thought. His breakthroughs make him widely considered the first modern geologist. \nIn 1809 William Maclure produced the first geological map of the USA\, a task he completed thanks to two painstaking years spent personally traversing the country. With the invention of radiometric dating in the early 20th century\, scientists could finally provide an accurate figure for the age of the earth by tracing the radioactive impurities found in rocks. It helped scientists to see that the Earth is one very old rock indeed! \nRocks have been essential for human development\, which is why we celebrate Old Rock Day and the wonder of the geological world. \nWhy We Love “Old Rock Day”\nGeology is cool\nStudying the natural world helps us protect\, preserve\, and predict it so that we can live in harmony with nature \nRocks are useful\nFrom the sturdy bricks of our homes to the sidewalk beneath our feet\, rocks are essential for human existence \nRocks are precious\nSome of the most coveted things in the world today — gold\, diamonds\, and other gemstones — are old rocks (minerals) \nReprinted from National Today – Old Rock Day URL:https://iafi.org/event/international-old-rock-day-january-7/ LOCATION:WA CATEGORIES:Other ATTACH;FMTTYPE=image/jpeg:https://iafi.org/wp-content/uploads/IAF-NGT3.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250106T190000 DTEND;TZID=America/Los_Angeles:20250106T203000 DTSTAMP:20260403T112331 CREATED:20241203T050037Z LAST-MODIFIED:20241222T012354Z UID:39253-1736190000-1736195400@iafi.org SUMMARY:Northern Ice DESCRIPTION:(2 Dec 2024)   Grace Sherwood Winer is a geologist and explorer who has done extensive studies on the melting of glacial ice in the Arctic.  She will present present her work on the islands of Svalbard and Iceland at our meeting on 06Jan2025 at 7:00pm at Bellevue College\, Building B\, Room 104.  Note room change!

The hike will start at 10:00 a.m. The hike will be led by Don Chadbourne\, geologist and board member of the Cheney-Spokane Chapter. You will meet the leader at the trailhead. \nDescription of Fishtrap Lake Hike\nThe hike will begin and end at the south trailhead at Fishtrap Lake. The hike will follow the south loop trail\, with a total length of about 5.5 miles. The trail is mostly single track over dirt and rock\, with an elevation gain and loss of about 500 feet. The hike will provide an intimate view of the channeled scablands that were carved out by the ice age floods. Features will include pothole lakes\, rock benches\, mima mounds\, kolks\, and streamlined and scarped Palouse hills. The hike will also provide wide open views of Fishtrap Lake and the surrounding country. This hike is included in On the Trail of the Ice Age Floods – Northern Reaches\, by Bjornstad & Kiver. However\, we will be following trails that were constructed after the book was published. \nDirections to the trailhead\nFrom I-90 take Exit 254 and proceed south 3.6 miles on the Sprague Highway. Turn left (east) on Miller Ranch Road and proceed 0.2 miles to the “T” at the Miller Ranch house. Turn right(south) and drive 0.8 miles to the trailhead parking lot. There is a vault toilet at the parking lot.
