Ruby Falls in Chattanooga

Photo of Ruby Falls included. I believe it is the world's tallest underground waterfall. Impressive. It is not easy to get a photo of it either, especially when you are using a small digital camera with no tripod and loads of other people walking around. In two trips, this might be the best one turned out for me. I consider myself a bit claustrophobic but I haven't had a problem visiting these caverns. I certainly can't imagine going in this cave as small as it was when they first discovered it though!
