A young woman named Julia Butterfly Hill climbed a 200-foot 1,000 year-old redwood in December 1997. She didn't come down for 738 days. The tree, dubbed Luna, was ready to be cut by a corporation and Hill's action was part of an Earth First! devised tree sit-in to protest the logging. "The Legacy of Luna", part diary, part treatise, and part New Age spiritual journey, is the story of Hill's two-year arboreal odyssey. Photos.
