Trenny Gibson accompanied 40 of her classmates from Bearden High School in Knoxville, Tennessee on a field trip to The Great Smoky Mountains National Park on October 8, 1976. The students were to hike down from Clingmans on the Forney Ridge Trail about 1.8 miles to Andrews Bald and then come back. The students separated into small groups when they arrived at the trails.
Trenny apparently hiked with several different groups of her classmates throughout the day. She was last seen at approximately 3:00 p.m. near Clingman's Dome.
Reports indicate Trenny was with a couple friends who stopped to rest along the trail. She went on and then she disappeared without a trace.
Tracking dogs detected Trenny's scent at the intersection with the Appalachian Trail. They followed it by Clingmans Dome Tower and along the roadside about a mile and a half from Newfound Gap when the scent was lost.
Extensive searches of the park continued until the end of October 1976, but she was never located.
