Jim O’Connor, Portland-based USGS hydrologist, will discuss “The Bonneville Flood – A Veritable Debacle.”

18,000 years ago, at Red Rock Pass in eastern Idaho, unconsolidated materials gave way to sudden overflow of Glacial Lake Bonneville. One of the largest floods on earth, the Bonneville Flood was a catastrophic outburst, with discharges lasting a year or more. GK Gilbert first discovered the flood in the 1870s while looking for the outlet of an inland sea that had cut prominent ancient shorelines above Great Salt Lake. His explorations led him to that spillway. Flooding carved canyons, cataract complexes, and built massive boulder bars, all of which help interpret megaflood processes and model hydrodynamics and landscape analysis today.

The program is free & open to the public.
