Volcano Views & Brews
This popular lecture series about volcanic topics began in 2007 and continues every month. Fascinating topics, lively speakers as well as excellent food and libations make for an enjoyable and horizon-widening evening.
NEXT in Vancouver: The Cataclysmic Ice-age Missoula Floods
with Jim O’Connor - U.S. Geological Survey
Where and When: Loowit Brewing Company 507 Columbia St. in Vancouver, WA on Tues. March 18th. Doors at 5:00pm, talks starts at 6:30pm. $5 suggested donation.
Description: EAt the close of the last ice age, 15,000-20,000 years ago, a lobe of ice flowing south from Canada blocked the Clark Fork River in northwestern Montana. The resulting ice-dammed lake, known to geologists as glacial Lake Missoula, was at times more than 2000 feet deep and contained 500 cubic miles of water—20 times the size of Puget Sound. The ice dam ruptured and reformed dozens of times, each break-out sending torrents of water across eastern Washington and down the Columbia River. The flood waters were in places 1000 feet deep and flowing at 30 or 40 miles per hour, lifting boulders the size of automobiles and tumbling them downstream. With such force, these humongous floods instantaneously shaped the landscape of the Pacific Northwest by carving the channeled scablands, depositing bars of sand and gravel 100s of feet high, and backfilling broad valleys with silt and clay. But the floods also shaped the science of geology. When these floods were first proposed by early geologist J Harlen Bretz, such catastrophes were loathed by geologists confined by an intellectual framework of slow gradual processes shaping the planet over millions of years. The debate raged for decades, with many twists and turns. In the end Bretz prevailed, but surprising findings continue to emerge, challenging our understanding of one of the greatest natural events in earth history.
Jim O’Connor is a Pacific Northwest native long interested in the processes and events that shape the remarkable and diverse landscapes of the region. Following this interest with a Geological Science major at University of Washington and M.S. and Ph.D. degrees at University of Arizona, he has spent the last 20 years focused on the “science of scenery” (as ascribed to the field of geomorphology), for the last 15 years with the U.S. Geological Survey Water Science Center in Portland, Oregon.
NEXT in Longview: From Pines to Penstemons- the Plants of Mount St. Helens
with Ray Yurkewycz - Mount St. Helens Institute
Where and When:Hop N’ Grape 924 15th Ave. in Longview, WA on Thurs. March 20th. Doors at 5:00pm, talks starts at 6:30pm. $5 suggested donation.
Description: Ever wonder what the heck that beautiful purple flower was you saw on your hike? We have a wonderful diversity of plants in the northwest, but their identification can be daunting at times. Come learn about plant identification basics as well as how plants responded to the 1980 eruption of Mount St. Helens.
Ray Yurkewycz earned his Master’s degree in Environmental Science from Washington State University – Vancouver, studying the impact of pocket gophers on plants and soil in the Pumice Plain region of Mount St. Helens. He is currently employed as a biologist for the U.S. Forest Service on Mount St. Helens where he gets to work with everything from shrews to salamanders, and trout to trees. Ray has also studied plants across the Great Basin Desert and Intermountain West while working for the U.S. Geological Survey and the University of Montana. He has worked for the Mount St. Helens Institute for going on 3 years.
April - John Bishop, Professor in the School of Biological Science at Washington State University - Vancouver, has studied the response of populations, communities, and ecosystems to catastrophic disturbance, with most of his work focused on Mount St. Helens.
May - Robert Michael Pyle, lepidopterist and author of The Butterflies of Cascadia: A Field Guide to All the Species of Washington, Oregon, and Surrounding Territories, Where Bigfoot Walks: Crossing the Dark Divide, and Wintergreen: Listening to the Land’s Heart, among many others.
