Missoula FloodsAt 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 2,000 feet deep and contained 500 cubic miles of water — 2 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.  

Join the Columbia River Maritime Museum for our next Science on Tap: Missoula Floods on Thursday, March 7, 2013 as Jim O'Connor revisits the flood waters that proved forceful enough to instantaneously shape the landscape of the Pacific Northwest.

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. With a M.S. from the University of Washington and Ph.D. from University of Arizona, he has spent the last 17 years with U.S. Geological Survey Water Science Center in Portland, Oregon.
