Geology Alive: Understanding Geologic Hazards in the Columbia Gorge

Columbia Center For the Arts 215 Cascade Ave, Hood River, OR, United States

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? Join 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! GET TICKETS HERE When: NOVEMBER 13th, 2024 | Doors 6pm, Show 7 pm Where: Columbia Center For the Arts, 215 Cascade Ave, Hood River, OR This event will be livestreamed on our Givebutter page: https://givebutter.com/geologyalive Doors 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. Richard (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.  

New Interpretations of Old Strandlines

Montana Natural History Center 120 Hickory Street, Missoula, MT

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. New “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. About 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. This is a live event that will not be recorded or streamed.

Terroir and the floods

(12Dec24) Scott Burns is back in March to talk about the impact the Ice Age Floods had on vinticulture in the Pacific Northwset.  Join us as Scott explains how the Floods influenced the regional properties of Northwest soils and ultimately made the Pacific Northwest one of the prime wine producing regions in the United States. The "virtual wine tasting" will happen at our chapter meeting 04Mar2025 at 7:00pm at Bellevue College, Building B ,ROOM 104.  This lecture will be in-person and livecast on Zoom.
