::::I don't doubt that you could form a canyon out of soft, wet earth relatively quickly. What I do doubt is that you can form a canyon out of hard rock (such as that found in the Grand Canyon) relatively quickly. [[User:Aurix|Aurix]] 13:47, 26 March 2010 (EDT)

:::::And who ''says'' the rock was hard when the water drained away? Every layer of rock seen on both sides of that canyon was laid down by water, and it certainly was not rock when it was laid down. [[User:Karajou|Karajou]] 13:49, 26 March 2010 (EDT)

::::::Are you saying the flood carved the Grand Canyon out of hard rock that already existed in the area by softening it? Or that the flood deposited around a mile of sediments in the area, and then carved the Grand Canyon out of that and then those sediments hardened? Or something else? Can you be more specific about the timeline of events that happened to form the Grand Canyon? [[User:Aurix|Aurix]] 14:28, 26 March 2010 (EDT)
