The rich soil of the Willamette Valley originated in eastern Washington and was brought by the ice age Lake Missoula Floods. It was this soil that attracted Oregon Trail pioneers to become part of one of the largest non-forced migrations in all of history. But did you know that from Pendleton to the The Dalles, some of the very trails the pioneers used were actually channels of those very floods? Join GO on October 10th, 7 PM at the Columbia Center for the Arts with author Rick Thompson for an exploration of how the Oregon Trail migration was made possible by flood geology. Thompson will take us on a visual journey of the flood channels through canyons, waterways and along the giant gravel bars the pioneers saw as they traveled using photos, LIDAR and maps.
Rick Thompson is a native Oregonian who is passionate about sharing the beauty and natural history of the great Northwest with others. A descendant of Oregon pioneers and rock lover, his intrigue with local land formations, huge boulders and glacial erratics, lead him to embark on a 20-year study of the effects of the largest ice age flood effects in NW Oregon and SW Washington. Rick is President of the Lower Columbia Chapter of the Ice Age Floods Institute which holds monthly public educational meetings in Tualatin. Rick is the authorof “GigaFlood – The Largest of the Lake Missoula Floods in Northwest Oregon and Southwest Washington” which is illustrated with his own photographs, maps and diagrams to show you the evidence still visible today from this catastrophic flood which so affected the Northwest.
