Well Steve , neither you, me, or anyone else alive now was around at the flood/Carboniferous, depending on presuppositions but I am sure both sides will offer an explanation of how features form. I would guess that folded solid strata was effected under intense heat. I don't see any reason why that should not happen under the massive upheavals in the flood year. Perhaps you have some idea of a tranquil rising of water rather than the geologic activity hinted at in scripture and part of the flood geology model.   One thing I would suggest is impossible is for trees to be preserved (that is..the same trunk) in more than one layer if each layer represents vast time periods, yet this is what is found, but it certainly fits the flood model where layers were laid down in quick succession.
