AUGUSTA, Maine — The family of missing hiker Geraldine Largay is offering a reward of $15,000 for information leading to the location of the woman last seen in July hiking on the Appalachian Trail in Franklin County, the Maine Warden Service announced Tuesday.

Largay, 66, was last seen by hikers July 21 and was reported missing July 24. A massive search involving several Maine agencies and hundreds of volunteers ensued. The search was scaled back on Aug. 4. Six more ground searches have been conducted since that date, according to the warden service.

The woman from Brentwood, Tenn., is described as 5 feet, 5 inches tall, 115 pounds, and has brown hair and brown eyes. Her trail name is “Inchworm” and she was last seen wearing a red pullover shirt, tan shorts, a blue hat and a black-and-green backpack. Largay is described as an experienced hiker who was prepared with supplies. She had no previous incidents during her hike leading up to her disappearance, according to the warden service.

Largay started her hike on the AT on April 23 at Harpers Ferry, W.Va. Her destination was Baxter State Park in Maine. Her husband, George Largay, kept track of her along the way and made frequent, pre-determined stops to resupply her, according to the warden service. On Sunday, July 21, she departed from her husband at the Route 4 AT crossing in Sandy River Plantation near the town of Rangeley. Later that day she texted her husband and advised she was on top of Saddleback Mountain.

Her plan was to stay at the Poplar Ridge lean-to in Redington TWP Sunday night. Investigators confirmed from hiker interviews that she did stay the night at Poplar Ridge Lean-To on the night of Sunday, July 21. On Monday morning she texted her husband and indicated she was again headed north on the AT with her next stop at the Spaulding Mountain lean-to. Her plan was to meet her husband on Tuesday, July 23, in Wyman Township at the Route 27 intersection with the AT. She never arrived at that location.

The Maine Warden Service was notified of her disappearance on July 24, and started searches and investigation that day. No clues such as clothing, hiker accessories or backpacking equipment that can be attributed as coming from Largay have been located from any ground search since it started.

The next phase of the search will be to wait for leaves to fall and have aircraft fly in areas where visibility is good and that have not been searched, according to the warden service.

Both the Maine Warden Service and the Largay family seek any information from hikers or others who have specific information related to Geraldine Largay and her journey on the AT, especially information related to the dates between July 21-23. Information will remain confidential. Those with any information are asked to call Maine Warden Service dispatch center at 624-7076 or
