They followed it by Clingmans Dome Tower and some of the dogs last detected her scent along the roadside about a mile and a half from Newfound Gap but then the dogs stopped, the scent had disappeared, according to source.

Gibson was last seen hiking with a high school group from Knoxville, Tennessee. She disappeared as the group hiked back from Andrew’s Bald Trail to the Clingmans Dome parking area.
