The geology of the site (and the rest of the rock record) is all part of what you need to deal with, if you want a sensible YEC model. Caves may be common, but you have limited time to explain how this one formed, and all the rest of the issues Joel raised. You have not even begun to make sense of the animals at the site, and suggesting that bear dogs, bears,and dogs are just minor variations of the same kind, and throwing in wolves, seals, and even some dinosaurs, does not help. In fact, it’s ludicrous, for reasons not worth my time to explain. At any rate, given all the animals you lump together in a kind, please tell us how many vertebrate kinds there were, what they were, and how you distinguish them. On the basis of “general appetite”, whatever that means? You say the fossil record shows the original world after the flood, but most YECs claim the vast majority of fossils (at least before the Cenozoic) were deposited during the Flood.
