Glacial Lake Missoula and Its Humongous Floods

Glacial Lake Missoula and Its Humongous Floods tells the tale of a huge Ice Age lake that, when it suddenly drained, unleashed more then ten times the combined flow of all the modern rivers of the world. The book follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured eastern Washington and rushed down the Columbia Gorge to the Pacific Ocean.
