I've read up through Faith's Message 615, and I think the most important part of your explanation that still hasn't gotten across is how a shallow sea can leave behind miles-thick sedimentary deposits. Once this point is clear then sedimentary deposits across the craton can be explained.
I didn't expect such a aggressively disagreeable reaction. Surprised me also.

Edge hasn't responded yet and will have to confirm, but when you say this:
Faith writes: 1) So, since you are not addressing Percy's idea that miles-thick sedimentary deposits are possible from a shallow sea I gather you are saying no, that is not possible, which of course it isn't. Edge's response was actually in his next paragraph, which you quoted:
Edge writes: The second point is that both continental and oceanic crust will subside due to loading by sediment and other tectonic factors. This means that sediment can continue to stack up without increasing the water depth. As I said, Edge will have to confirm, but I believe he's agreeing that miles-thick sedimentary deposits are possible from a shallow sea. That's how the Michigan Basin formed. Here's that image again. Note that the depth of sediments grows to over a couple miles, and the water depth was never near that great. It was a shallow sea, the lowest point in the region, and it accumulated sediments over time that with the weight of increasing thickness gradually subsided into the continent:
This is from the Wikipedia article on the Michigan Basin:
quote: The same process of accumulation of sediments and subsidence took place all across the craton wherever there was net accumulation of sediments. Higher and more mountainous regions were areas of net erosion and served as a source for the sediments. I'm not trying to participate in the discussion, just trying to keep the discussion moving forward. As I said, Edge will have to confirm.

edge writes: I believe I already explained what would have to happen for the water not to have to rise miles to cover miles of sediment in Message 514. Each deposit sinks so that the next can be deposited in shallow water. That explanation seems to cover it.
And that explanation has been refuted. It's a little ambiguous which parts of the explanation have been refuted. If it includes the "Each deposit sinks so that the next can be deposited in shallow water" portion then I think some additional explanation could be helpful.

Frankly, I'm not sure what Faith was trying to say here. It sounds like Faith was agreeing, but that couldn't be the case. Faith will have to confirm, but I think her scenario was that each tide left behind sedimentary deposits that due to weight subsided downward, then the next tide would come in and the process would repeat. I think there is agreement about sedimentary layers subsiding. What needs to be understood is why Faith doesn't accept subsidence in the context of the Michigan basin that formed through subsidence of accumulating sedimentary layers beneath a shallow sea:
As always, I'm seeking to confirm my own understanding, so please provide any corrections or missing information.

Just a word of explanation:
Faith writes: Yes, well perhaps your imagination is better than mine. I'm open to adjusting my scenario if necessary. Yes I figure as the sea was rising with the Flood the tides would have to have reached very far onto the land. How far? I dunno. A long distance, reaching farther with each tide because of the rising of the sea. And you don't see that as a problem. Hundreds of kilometers would not be a problem? Every 6 hours? No. And it's twelve. High tides are twelve hours apart, and low tides are twelve hours part, but each tidal cycle consists of a high tide and a low tide 6 hours apart. The water rushes in for six hours to reach high tide, then it rushes out again for six hours to reach low tide, a total of twelve hours. Then the process repeats. Clarifying Edge's point, he's questioning your scenario because it requires a tide to rush in hundreds of miles in only six hours, and then to rush out again in only six hours. To pick a simple example, if the tide was rushing inland a distance of six hundred miles then it would require the tide to flow in and later flow out at the rate of one hundred miles per hour. This is why Edge is questioning how animals could have time to run in any distance to leave tracks, and how the tracks and nests with eggs could be left behind in such violent water, and how fine sediments could have been deposited, and so forth. Edge will have to confirm whether I've stated his concerns accurately. Edited by Admin, : Clarify writing.

Only that it happens. This point of agreement might serve as the beginning of an expanding area of agreement.

Faith writes: But where have I said they have to move hundreds of miles? I don't think I've had a clear idea of how far inland the tide had to come, just a "long" way, and that its length would depend on how high the sea had risen, reaching father with each rise in sea level. That's what I said in what I was quoted as saying. Maybe somewhere I speculated on hundreds of miles? If so, consider this a correction. To make sure there's a clear understanding of your scenario, let me restate this back to you: The geologic layers we see across most parts of all continents were formed gradually by repeated high tides of slightly greater than normal proportions over a couple hundred days. Rising flood waters caused the tides to encroach further and further onto the continent, and subsidence of the deposited layers allowed more layers to be deposited on top.
I have to keep coming back to this basic fact that being buried in mud describes all the fossils... Just a quick correction: being buried in mud only describes a subset of fossils.
...their layering in stacks of different kinds of sediment with no evidence of the kind of surface effects that would occur from spending any time at the surface of the earth... Another quick correction: nests and burrows and rivers and canyons and so forth are surface effects that are observed in buried layers.

Faith writes: That's OK but I do think of the Flood as occurring in stages so that the tides would only be a factor as it was rising, possibly also as receding; then after it reached its highest level (and I'm still not clear how long each of these phases would have lasted) the water would have been fairly quiet and sediments would be precipitated out of it. And I've not decided about the subsidence factor, merely consider it as a possibility. The water could have risen three miles according to at least one commentary I read. Again, let me try to restate your scenario: Tides occurred while flood waters rose. Animals would leave behind tracks and burrows and nests at low tide that would become buried by sediment brought in by the next high tide. You haven't yet worked out how tides interact with rising flood waters to create a series of layers containing tracks/burrows/nests.
I have to keep coming back to this basic fact that being buried in mud describes all the fossils... Just a quick correction: being buried in mud only describes a subset of fossils. The vast majority, all the fossils in the strata. But the others are formed how and where? What about fossils in sandstone and limestone?

Faith writes: Nooooo, we assume the Flood and try to prove it from the observed facts. Stating this another way, you're starting with a hypothesis that a global flood event around 4500 years ago is responsible for the geology of the Earth we observe today, and this thread is assessing how well this hypothesis measures up against facts and observations. Several people have questioned the way you think a global flood would behave, and I think this deserves more attention.

Just a quick correction, since no one else caught this:
Faith writes: Well there are places with no geological column, but you do seem to be forgetting the oceans, where there is also no geological column. The geologic column also exists beneath the oceans. Most of the sea floor has a maximum age of only a couple hundred million years because the ultimate fate of most sea floor is subduction into the mantle.
