On December 23, cavers were exploring a cave that begins 1000 feet inside the mine tunnel. A thirty foot drop was found to have a rope ladder rigged, made of polypropylene rope with 1 by 4 pine rungs. After exploring they headed out. While ascending the ladder, one of the rotten rungs broke. The cavers were able to ascend anyway, all with belays.
