Kelly Hill Caves

A very large limestone cave that runs under much of Kangaroo Island, discovered when a man riding a horse (Kelly was the horse, not the man :-> ) fell in. Neither was injured.
Cave shot The Wildlife Refuge people have put lights and paths in the cave, but otherwise have not disturbed the formations.
Ledge This formation occurred when the lower cave dropped and formed a ledge
Bacon formation Wide stalactites with striations are called "bacon" formations
Fishhook formation Experts don't have a good explanation for how some formations defy gravity and start growing upward.
