Evening Lecture: New Thoughts on Glacial Lake Missoula Shorelines
February 27, 2019 @ 7:00 pm - 8:00 pm$5
Unusual Wave Activity in the Bitterroot Arm of Glacial Lake Missoula
A lecture hosted by the Glacial Lake Missoula Chapter of the Ice Age Floods Institute: New Thoughts on Glacial Lake Missoula Shorelines.
Did Glacial Lake Missoula have tidal waves?
Recent Lidar images in the Bitterroot Valley suggest that earthquake activity in the Pleistocene may have caused large waves to crash on the shores of Glacial Lake Missoula.
Jim Sears, geology professor at the University of Montana, will present the latest work by Mike Stickney and Jeff Lonn, entitled “Investigation of Late Quaternary Fault Scarps along the Bitterroot Fault, 2017” and other geologic investigations. Not only do the bare-earth Lidar images outline the shores of Glacial Lake Missoula, but they indicate the recent faulting along the Bitterroot Front and suggest that it is more seismically active than previously thought. Additionally, learn about how the lake has been dated and the relationship of glacial deposits.
