Grandma Gatewood's Walk by Ben Montgomery

Grandma Gatewood, as the reporters called her, became the first woman to hike the entire Appalachian Trail alone, as well as the first person—man or woman—to walk it twice and three times. Gatewood became a hiking celebrity and appeared on TV and in the pages of Sports Illustrated. The public attention she brought to the little-known footpath was unprecedented. Her vocal criticism of the lousy, difficult stretches led to bolstered maintenance, and very likely saved the trail from extinction.
