GEOLOGY – The local chapter of the Ice Age Floods Institute is involved in three public educational events this month.

Friday, May 6, lecture -- “Spokane Before, During, After Glacial Lake Missoula Outburst Megaflood,” 7 p.m., Lair Auditorium, Building 6, Spokane Community College. Free.

Details: The Spokane Valley has a rich history, both geologic and human. Michael B. McCollum will discuss the geology and resulting landforms that attracted those that first settled along the Spokane River and its falls. There will be a provocative discussion about whether a single catastrophic collapse of the Purcell Trench lobe restraining glacial Lake Missoula ~16 ka (calibrated), caused an outburst flood that filled Glacial Lake Columbia with sand and granule gravel to a thickness of up to 700 feet. Post-Missoula flood was a time of meandering rivers and streams reclaiming their drainage basins by eroding through the unconsolidated flood fill. The river incision was punctuated by falling glacial lake levels, resulting in the numerous boulder gravel terraces and benches that line the Spokane River today.
