Glacial Lake Missoula extended through the Bitterroot Valley as far south as Darby, Montana. It flooded the Clark Fork valley as far eastward as Drummond, all of the Jocko, Camas Prairie and Little Bitterroot valleys, and the Mission valley as far north as Polson, where waters lapped against another icy glacier.
At the end of the ice age 10,000 years ago the earth trembled. The glacier moved. Ice nudged boulders. Soon, racing water-born, the earth's migration began on a mutinous roar. The ice dam ruptured a final time. The 2000-foot-deep water behind the dam, estimated at 500 cubic miles, rushed out at two hundred times the flow rate of the Mississippi River at maximum flood. The wall of water surged and tumbled at a rate of 45-60 miles an hour.1. Eight to ten cubic miles of water per hour, scouring all sediment from rocks in the narrowest parts of the drainage causing the greatest flood catastrophe the world has ever known occurred. It rampaged with the force equal to 60 Amazon Rivers.
