Not quite correct. It is proposed that many of the sediments were still
reletively soft when the uplift of the Colorado Plateau and the upwarp
of the Kaibab plateu occurred. It is also proposed that many of the
limestones hardened quite quickly, much as concrete does.

Or, the limemud was deposited quite quickly, which then hardened fairly
quickly as it was upwarped. The high precipitation of the Post Flood
Ice Age eroded the caves in the uplifted plateaus much more quickly than
now.

Above the Redwall limestone is 300-400 feet of the Supai group of
sandstones, shales, and limestones, 100+ feet of the Hermit shale,
200-400 feet of Coconino sandstone, 100 feet of the Toroweap formation,
100 feet of the Kaibab limestone, 200-300 feet of the Moenkopi
formation, 40-50 feet of the Shinarump congolmerate, and then the Chinle
formation. One would expect that the caves would also have some of all
of the other formations before you would get the Chinle in the caves. I
think you may have ment the Supai group.
On the Kaibab plateau, through which Grand Canyon is carved, the
Moenkpi, Shinarump and Chinle and layers above have been erodded away,
leaving the hard cement-like Kaibab limestone. It is proposed that as
the Rocky Mountains and the Colorado Plateau were uplifted during the
latter stages of the flood, a great surge of water ran off the area
across the area around Grand canyon, stripping the layers of down to the
kaibab limestone. Then the Kaibab plateau was uplifted due to faulting,
forming a dam to runnoff from the Area now drained by the Colorado River
and its tributaries.

I think you had better check of the name of the formations that have
collapsed into these caves. I suspect that those caves are filled with
the Supai group, Hermit shale, Coconino, Toroweap and the Kaibab.

These channels simply represent channelized erosion from temporary,

I looked through supposed "worm borrow" samples in the vault here at the

are anything more than curious random shapes in the mud.

It is obvious from this that you have not read the breached dam proposal
by Austin and others. The theory that the plateau was slowly uplifted
as the river cut through it has been proved wrong ages ago, when they
found the muddy creek formation. The most current theories have no
evidence and evidence.
