Of course, that’s just the begging of their geologic problems. What many YECs don’t realize is that while there are strata indicating moderate or rapid deposition,every period of the geologic column contains many other strata indicating extensive periods of slow or calm deposition, or wind-blown/dessert deposition, river deposits, and paleosols (often undisturbed ancient soils)–leaving literally no place to put a global Flood. As I’ve noted before, further compounding these problems are extensive dinosaur trackways at thousands of sites around the world, and hundreds of vast dinosaur nesting sites (which Ironically, occur in the Mesozoic, which is often depicted by YECs as representing the peak of the Flood), plus many other trace fossils incompatible with Flood deposition, such as desiccated coprolites (fossil poop). http://paleo.cc/ce/tracefos.htm
