The Bonneville Flood was one of the largest floods on Earth. The cataclysmic flood-from the rapid 115 meter drop of Lake Bonneville from the Bonneville level to the Provo level-was nearly 200 meters deep in places and flowed at a maximum rate of about 1 million cubic meters per second — about 100 times greater than any historical Snake River flood. Jim O’Connor has worked at the U.S. Geological Survey since 1991, intent on improving understanding of the processes and events that shape the remarkable and diverse landscapes of the Pacific Northwest.
