Very often the footprints are made much lower. Tracks have even been found in the Hermit shale below, implying that the animals began walking uphill even while the flocculated silt and clay were being deposited.

So what?
The scenario described is a catastrophic world wide flood in the middle of laying down 600 feet of one of several desposits. It doesn't matter if there were other layers of foot prints lower down(though you have to explain why there would be more than one -- everything was killed in the 40 days of rain -- was it not?). There are footprints near the top. While the whole earth is under water?
Those foot prints near the top were what you have been asked to explain. Pointing to ones lower down doesn't seem to do that.
Since you think that the layers at the bottom of the canyon are not deposited by recent floods, what happened to the debris deposited by the river?
I think you can figure that one out yourself. Have a go at it.
I believe that the Bright Angel shale and Tapeats were not deposited by the flood.
They are deposits of the river which cut through the canyon.
If this is true then I assume there will be no continuation of these layers back away from where the river has cut. They will be local deposits surrounding the river. Is that what you would say?
In addition, there are 5 more formations abouve the Bright Angel and Tapeats, you neglected to explain those.
PH, leaving out most of the issues and focussing on one or two (some seemly totally irrelevant) doesn't make for a complete explanation.
Oops Randy beat me too it. Sorry about the duplication.
