Who is this? The Antique Cave Duck – the only critter we guarantee you will see. This duck has history in the cave. For over 75 years the duck has been perched in the same spot, his own duck pond, and has been photographed more than any other critter in Bluff Dwellers Cavern. He sits on the edge because in his long life he can’t swim when the cave floods. Come see the beautiful cave and The Antique Cave Duck.
