Nice photos, do you work for National Geographic? Probably not since you missed the story about the Burlingame Canyon carved out in 6 days by water - a smaller version of the Grand Canyon but obviously caused by less water.
When an abrupt cataclysmic flood happens, smooth rocks don't appear, that takes thousands of years.
Massive amounts of water carves out many canyons (if not all) and this powerful water traveled as far up the mountains as life goes, maybe 17k feet? That's over three miles of water. And then of course it descended for many months before the Ark came to rest at about 14k feet on MT. ARARAT.
Remember, it did not all come from the sky, it came from beneath the surface. And very possibly, an asteroid hit around the Gulf of Mexico that not only jarred the earth but created massive waves - able to travel thousands of miles.
A Canyon in Six Days!
