Nowhere in the canyon does that condition exist.
All of the walls of the canyon are in typical repose for rapidly erroded sedimentary mud.

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 you’ve 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?

So the water was hot? Because….
