On Sunday, September 15, three cavers were surveying in McFerrin Breakdown Cave in West Virginia. At one point George Dasher was checking in a breakdown area for the proper route, and came to a 15-foot pit. He started to ease over the edge of this climb down but an "immense" boulder moved under him and he jumped to one side. The huge rock went into the pit with a "terrifying boom." Dasher had just enough time to yell "I'm all right!" before he slipped into the pit as well. He landed on his rear end and luckily was unhurt. They continued the survey.
