We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
This is much more ancient, but there's an interesting theory that the English Channel was formed when water, dammed by ice, broke through and cut a massive channel in the chalk, about 450 thousand years ago.
A show with the same premise played the other night on Smithsonian Channel in the U.S. It also detailed the formation of the Scablands in the NW U.S. and a similarly formed canyon in Iceland. Apparently these large ice dam floods were somewhat common in past ages...
A search for Glacial Lake Missoula will yield a wealth of information--videos, lectures, publications--from general interest to academic tomes on this geologic event. Even a casual look will open your eyes to the power of moving water.
