Nowhere in the canyon does that condition exist.
Sure. Nowhere in the Grand Canyon are there vertical cliffs .except for ones like these:

Having considerable experience with water running over recently placed earth embankments, it is obvious that they are a perfect microcosm of the creation of the Grand Canyon. The size of the area is irrelevent, since the amount of water was proportional. The hardening into stone is the same issue the world over, and is due to the fact that all of the deposited material was dissolved in hot water loaded with carbonates, the world over, and by cooling and drying it would inevitably become some form of calcareous stone.
You are a surveyor so I presume youve been to many construction sites. So let me ask you what happens to say an 8 to 10 deep earthen trench without shoring or a building foundation without shoring and before being poured with concrete or being lined with foundation stone? Would you be willing to stand in either of those without shoring? And most importantly, would you be willing to stand in either of them during a rainstorm absent any shoring?
and is due to the fact that all of the deposited material was dissolved in hot water loaded with carbonates
So the water was hot? Because
.
The water was hot because it came from scores of miles below the surface as “the fountains of the great deep” were ruptured.
And your question re: a trench is a nonsequitur WRT this discussion. Trench failures are always due to wedge pressures on the side of the trench; no such pressures exist in a sea of mud.
Run the water on a fresh pad and watch a miniature grand canyon form before your eyes. It happens every time perfectly.
Thanks.
Thanks.
