Caves over 1 mile long
This is the current "official" list of Florida caves over 1 mile long. Compiled by Bob Gulden of the NSS, it lacks some obvious big dry caves like Catacombs and Briar. I will be adding to this list soon to update the missing caves. The list will also soon reflect recent big discoveries like Werner Cave (when we get her surveyed.)
