No injured cavers recorded.
On September 19, 1981, a group of 8 cavers from the Nashville Grotto were on a clean-up trip to Grassy Cove Saltpeter Cave in Cumberland County, Tennessee.
After the clean-up they did some exploring, Jean Smyre was climbing when a handhold broke. The fall resulted in a broken arm. The Cumberland County Rescue Squad carried out the evacuation.
Analysis: Too little information - when free climbing keep three points of support and, when circumstances dictate. use a belay.
