How could the Flood deposit layers of solid salt?
Such layers are sometimes meters in width, interbedded with sediments containing marine fossils. This apparently occurs when a body of salt water has its fresh-water intake cut off, and then evaporates. These layers can occur more or less at random times in the geological history, and have characteristic fossils on either side. Therefore, if the fossils were themselves laid down during a catastrophic flood, there are, it seems, only two choices: (1) the salt layers were themselves laid down at the same time, during the heavy rains that began the flooding, or (2) the salt is a later intrusion. I suspect that both will prove insuperable difficulties for a theory of flood deposition of the geologic column and its fossils.
