The search for a missing hiker on a rugged section of the Appalachian Trail in western Maine is now entering its sixth day.

The Maine Warden Service is narrowing the search area as it tries to determine what happened to 66-year-old Geraldine Largay of Brentwood, Tenn. She contacted her husband on July 21 from the top of Saddleback Mountain but failed to meet up with him as planned the following day.

Authorities are focusing on a 14-mile section of the trail in Carrabassett Valley, but believe the best chance of finding the missing hiker is in a nine-mile stretch between Lone Mountain and a dirt road west of Sugarloaf Mountain.

The original search area covered more than 80 square miles.

Largay was trying to complete a hike she began in April.
