It washed down the canyon when the Flood waters were receding, along with the broken strata from the uppermost layers, and some just got buried out of sight, and some became Vishnu schist.

Do you have any idea as to what schist might be, Faith? Even a whiff of a clue?

Faith writes: So if you are implying that mud might have ended up as a flat mudstone rock in the stratigraphic column, the task I'm asking of you is to show how the lake bottom mud became that rock. Through pressure and long time periods. The process is called lithification: Lithification - Wikipedia

Made up of many different kinds of rock or minerals metamorphosed by the heat of the volcano beneath the Grand Canyon, the volcano that also produced the granite in that same area.. The abrasion of the original strata by the movement I have in mind would certainly have produced a huge collection of different kinds of particles and the volcano would have metamorphosed them all into a multi-content rock.

You seem to have some specific kind of effect in mind that you call shearing. It is quite clear, however, that there was tremendous movement between the basement rocks and the Tapeats as evidenced by the huge boulder of quartzite embedded in the Tapeats that is a quarter of a mile from its source in the Shinumo. That's a lot of movement. I hypothesize that the quartzite was hard enough to resist breaking at the Great Unconformityh as most of the lower strata did, and some of it penetrated into the strata above, which were still wet as the Flood was just beginning to recede. Are you saying the Dox and the Hakatai are as hard as quartzite? Anyway, there is evidence of horizontal movement even if there isn't evidence of shearing.
So, why do the Dox and Hakatai not also penetrate across the Great Unconformity? In order to do this you need the Shinumo to act independently of the other two formations. That means they should show relative motion (fault contacts) with the Shinumo. But there is no such evidence. Do I read you correctly? The Dox and the Hakatai broke off at the GU, the harder Shinumo didn't. I don't know if that requires fault line evidence. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

But you have to place your lithified mudstone in the stratigraphic column. Getting it lithified isn't the problem, getting ANY sediment lithified in the right order between other lithified sediments in the right place, all maintaining a similar flatness, is the problem.

Well, the lake would have to form on something, so that would be bottom of the sandwhich. Water and wind would tend towards eroding lumpiness of the bottom layer. Could this be occurring on top of a stack of lithified layered flat sediments of different types? If so the one the lake sits on would have to have been extremely dry or the mud would simply mix with it, and that should be a problem with every layer in the stack. Each has to be hard and dry before the next is deposited. But in that case nothing could live on any of the rocks while they are drying. Goodbye life of the Permian or the Triassic periods. I also don't believe the processes you are describing could produce the degree of flatness we see in the layers of the column, but that's just a supposition..
The mud that goes on top of it is likely to form a flat surface because it is wet and it will settle flat. Any additional lumpiness that forms may also be eroded over time by the water. When the lake dries up the top layer of mud may well be eroded away leaving the flat middle layer of the sandwich. Then some other depositional environment deposits sediment in a different way on top of this middle layer to create the top layer. The different depositional environment results in a different type of sedimentary rock formation. I'm sure this must be about the best anyone can do to rationalize this explanation, but I find it every hard to accept that different sediments just happen to come along to form a new flat frock on top of another, that must have been completely hard and dry or it would all mix together and not look at all like the clearly demarcated layers of the stratigraphic column. And there has to be a lot of them, as we see in the Grand Canyon walls, all quite similar in form climbing up a whole mile. Seems to me Geology believes in a complete impossibility.
If the sediment is derived from the surrounding terrain, this would take care of that part of the situation too, but maybe some of that that was eroded and deposited elsewhere by wind. Not sure what your point is here.
So let's see - the first layer contains marine life from a million years ago, the middle layer contains lake life from 600,000 years ago and the third layer contains land fossils from 250,000 years ago as it was I dunno a swamp. Each layer is flat, the surrounding contemporaneous terrain was eroded away to create those layers, and organisms that died in the sea/lake/swamp may have been buried in such a ways to preserve their remains in some fashion. I can't really picture how all this works but I'll just accept it for now. Getting this whole thing situated on top of a stack of sediments and beneath a stack of sediments without mixing them together and while allowing living things to go on living, seems problematic.

Getting it lithified isn't the problem, getting ANY sediment lithified in the right order between other lithified sediments in the right place, all maintaining a similar flatness, is the problem. It is already part of the stratigraphic column as soon as it is deposited. As more sediment forms on top of the mud it moves down the column.

The task I described was to explain how a particular time period scenario gets from there to its representative rock in the stratigraphic column. It's a specific rock. The mudstone example was just a purely hypothetical example.

If so the one the lake sits on would have to have been extremely dry As I understand the process, being dry is an important component in lithification.
Each has to be hard and dry before the next is deposited. As hard and dry as stone, in fact.
But in that case nothing could live on any of the rocks while they are drying. Goodbye life of the Permian or the Triassic periods. There can be mud on top of the rock. Its the buried mud that turns to mudstone as the pressure caused by the weight of the mud above it compacts it and squeezes out the water. That mud may erode away before the next depositional scenario begins, or it may be present when it begins. That doesn't really matter. The point is that as stuff gets added to the top, it compresses what's beneath into stone. Over time, the types of stuff that gets added to the top changes as the environment changes resulting in layers of rocks.
that must have been completely hard and dry or it would all mix together and not look at all like the clearly demarcated layers of the stratigraphic column This does seem to be a problem for the Flood scenario. Don't see the problem for geology. Edited by Modulous, : No reason given.

There is no evidence of faulting or shearing fabric on the Great Unconformity.
That's a lot of movement.
Not for boulders in a wash. I see it almost every day.
I hypothesize that the quartzite was hard enough to resist breaking at the Great Unconformityh as most of the lower strata did, ...
They do not show breakage or deformation due to faulting.
... and some of it penetrated into the strata above, which were still wet as the Flood was just beginning to recede.
THere is no pathway for the boulder to reach it's present position due to tectonism.
Are you saying the Dox and the Hakatai are as hard as quartzite?
No, I'm saying that if the Shinumo was thrust up into the Tapeats while the softer formations are not then there should be additional tectonic contact of them with the Shinumo. In other words the Shinumo moved (according to you) but the Hakatai and the Dox did not.
Anyway, there is evidence of horizontal movement even if there isn't evidence of shearing.
You have shown us no evidence.
The Dox and the Hakatai broke off at the GU, the harder Shinumo didn't. I don't know if that requires fault line evidence.
So this fault of yours has to climb up and over the Shinumo high points and leave no evidence it happened. Sorry Faith, but in all such cases of faulting there is evidence for movement. And in soft sediments, even more so. And of course the Tapeats was soft. It was just being deposited. Much of the sand grains were derived from the Shinumo.

Why? Why wouldn't flat lying sediments produce flat lying rocks?

Why? Why wouldn't flat lying sediments produce flat lying rocks? The strata in some cases cover thousands of square miles of unbroken flatness, between others of similar flatness. The Tapeats covers most of North America, so does the Redwall Limestone. Reqally, this is not how the surface3 of the earth is built up. It doesn't happen. This whole scenario is absurd. I don't know how you or any geologist got yourself persuaded of such nonsense.
