An inexperienced spelunker spent seven hours trapped under a waterfall 200 feet underground in the Great Smoky Mountains National Park before he was rescued Wednesday night. Dozens of rescuers worked for nearly three hours before carrying John Moscheo, 23, out of Bulls Cave near Cades Cove in the park. He was airlifted to the University of Tennessee Medical Center. He had no serious injuries. Moscheo had been caving with an experienced spelunker, but he was unable to climb up from the ledge. It took the rescuers to get him out of the cave.
