I count 8 different levels at which footprints occur.
Lets do some math here.
The column I described is the entire geologic column in that part of the world. It works out that during the year of the flood, only .65 meter was deposited there per day. This means that the dinosaur footprints at the top of the Boonton formation was deposited at the end of the Flood year. Were they clumps of roots. These are not trees, they are roots of plants.
