- I have also encountered it (I think) in Andros. They have two blue
- holes there that have freshwater on top, a layer of the stuff you
- descrive, and saltwater below which eventually connects to the ocean.
-
- Uncle Charly's blue hole looks very inviting, and it is fun to swim in.
- The divemaster's at Andros Beach Hotel will not take you diving there,
- and recommend very strongly that you don't dive there. (At least one
- diver is known to have drowned in a tunnel there).
-
- The other one I visited in should be called a green hole (I can't
- remember the name but it is near the Andros Beach Hotel.
