There's one other question I have with the rapid creation model the YECs bring forth for the Grand Canyon. IIRC, the North Rim is over 2000 feet higher than the South Rim. If the land was there and flooded and some sudden run off cut through the "semi-soft mud", why didn't it run down hill? Why doesn't the canyon run from the North to the South? Why doesn't it look like the typical erosion we see when water runs down a hillside?
