Julia Butterfly Hill (born February 18, 1974 as Julia Lorraine Hill) is an American activist and environmentalist. Hill is best known for living in a 180-foot (55 m)-tall, roughly 1500-year-old California Redwood tree (age based on first-hand ring count of a slightly smaller neighboring ancient redwood that had been cut down) for 738 days between December 10, 1997 and December 18, 1999. Hill lived in the tree, affectionately known as “Luna,” to prevent loggers of the Pacific Lumber Company from cutting it down.
Hill lived on two six-by-six-foot platforms for 738 days. Luna’s trunk was her sidewalk and exercise treadmill. Hill learned many survival skills while living in Luna, such as “seldom washing the soles of her feet, because the sap helped her feet stick to the branches better.” Hill used solar-powered cell phones for radio interviews, became an “in-tree” correspondent for a cable television show and hosted TV crews to protest old-growth clear cutting. With ropes, Hill hoisted up survival supplies brought by an eight-member support crew. To keep warm, Hill wrapped herself tight in a sleeping bag, leaving only a small hole for breathing. For meals, Hill used a single-burner propane stove. Throughout her ordeal, Hill weathered freezing rains and 40 mph (64 km/h). winds from El Niño, helicopter harassment, a ten-day siege by company security guards, and intimidation by angry loggers.
