Cataclysms on the Columbia is interesting reading, but the ideas of the floods were proposed long before 1987 (J. H. Bretz published the first major report on them in 1959) and they are now long accepted as being what created the "Channeled Scablands" of E. Washington, and Dryfalls near Grand Coulee, giant ripple marks in the same area, etc. The ice dam that formed glacial Lake Missoula (around 20,000 years ago was at the north end of present Lake Pend Oreille, just north of where I currently sit in N. Idaho. Incidently, the floods happened several times and the last (and possibly greatest) released a volume of water equal to a flow about 10 times the present flow of all the rivers in the world (9.5 cubic miles per hour). Just incase anyone is interested. Lanny
