Journey Into One Of The Largest Caves Ever Found

Deep inside this cave lies the biggest underground room in America. This trip took us 9 hours to complete and involved rappelling down 2 pits. In between the pits were hours of grueling low crawls, and we had to climb up 2 waterfalls to get to the room. At the bottom of the massive room was a gigantic river that goes for miles.
