Ah, that's a sad story. Geraldine Largay, age 66 when she got lost in the Maine woods while taking a pit stop off the Appalachian Trail in July 2013. She had been hiking with a friend for several months on the AT, starting from West Virginia, but the friend had to leave the hike in New Hampshire due to an ill family member. Ms. Largay insisted on pressing on alone, even though her friend described her as anxious, and terrible at finding her way. She was otherwise tough and competent, managing to live for another month or so at a campsite she made that was later found to be a mile or two off the trail. Weeks of searching by hikers and helicopters didn't find her; her remains were found two years later by a logging surveyor.
