Around 13,000 years ago, Lake Missoula was one of the largest freshwater lakes in the history of the world. It was formed by glaciers plugging the outlet of what is now Lake Pend Oreille in Northern Idaho. When the water got deep enough, the ice floated and the dam burst. It might have been the biggest flood in the earth's history.


Lake Pend Oreille (a very very large lake) is the tiny remnant of what is referred to as Lake Missoula (the lake was 900 feet deep at Missoula, which was 160 miles upstream).


The water volume discharge rate is estimated as 200 times the maximum ever measured flood volume of the Mississippi River and 750 times the average discharge of the Amazon River!


The photos in this gallery are of land affected by the lake and the floods. I hope you enjoy viewing them.
