When you take the tour at Grand Caverns in VA, the guide tells you that the cave has more cave shields than any other in the world. Don't know if that is true, but there are probably hundreds. Someone counted a few years ago when it was resurveyed, but I can't remember the number was. Some are pretty big, too. Eight feet across or so. Grand Caverns in the number 2 cave the US, ya' know.
