I have to than John Hardly for teaching me a new word that I should have known long ago - I didn't know that "antediluvian" meant the period before Noah's flood. Makes me wonder why I studied Latin for six years and still stayed so dumb.
Thanks, John.

So, I thought the Canyon was mainly the result of erosion from lots of floods. Was it tectonic movement instead, or what?
