Othello Sandhill Crane Festival

Othello, WA WA, United States

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 General 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. Friday 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. Saturday, March 22 there will be several talks on geology at the Crane Festival.. Ice 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 Coulees, 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 the 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? Coyote 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. Sunday, March 23, Geology Field Trips Mega 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 rimmed 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. SONY DSC The 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

Plan on carpooling.  We have, at most, about 30 parking spots at Stop 1. There will be very little hiking associated with this field trip.  On all stops, we will be within a couple of hundred feet of our automobiles. There are no restroom or picnic facilities along our field trip route.  Therefore, we will break briefly so you can make a very quick trip to Cle Elum between Stop 3 and Stop 4.  Plan on eating lunch/snacks on the road or at the stops.  There won’t be a formal lunch stop given the lack of facilities and time. Dogs and kids are fine to bring as long as they are well-behaved. Dress for the weather.  Early April here can vary from sunny and warm to windy & chilly, all in a day!  A windbreaker is a really good idea. I will post a pdf of the field guide by 19 March on my CWU website at https://www.cwu.edu/academics/geography/_documents/karl-lillquist.php.  Scroll down the page to “Field Guides”.  You will find it under “Margins of the Eastern Cascades”.  Feel free to download and bring it on the field trip in digital format or print it out. The Ellensburg Chapter of the Ice Age Floods Institute will also provide ~40 hard copies of the field guide for the trip.  There is no cost for the field guides.  However, if you are not a member of the Ellensburg Chapter, please consider making a donation to the chapter to help cover the costs of the field guides (each cost ~$12). I hope you can join us on Saturday April 5th. Karl Lillquist

Mapping the Pacific Northwest’s Glacial Legacy

Cheney Community Library 610 1st St, Cheney, WA

Enhanced LIDAR images (WA-DNR) Glaciers 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. Geologists 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. Using 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. Presented in partnership with Ice Age Floods Institute (IAFI) This 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. Note: as of April 2 at 9 PM there are still 33 in-person seats available and 93 online seats available! Registration is required.

Tom Pierson – Geology of the Gorge

White Salmon Valley Community Library 77 NE Wauna Ave, White Salmon, WA, United States

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.   This 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.

How the Ice Age Floods Changed the Course of the Palouse River

Moran Prairie Library 6004 S Regal St, Spokane, WA

Palouse Falls - Photo Glenn Traver Before 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. In 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. Presented in partnership with Ice Age Floods Institute (IAFI) (Registration required on SCLD website. Registration opens at 6:30 PM Monday, March 31, 2025.)

Canceled 1.5 Million Years of Climate Data from the Antarctic Drilling Project

(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.
