Three missing person incidents, however, still are unsolved and are known internally as "the big three."
WVLT-TV reported the disappearances of two children and one adult in different parts of the Smokies in different decades still are puzzling.
Six-year-old Dennis Martin disappeared while playing at his family's campsite in 1969. In 1976, 16-year-old Trennie Gibson was last seen on a field trip with her friends. Polly Melton, who was 51, disappeared from a popular hiking trail in 1981.
Park spokesman Bob Miller said it's likely the woman and the teen were either taken out of the park or left willingly. Officials think the young boy never left.
