On December 10, 1997, Julia Hill ascended an ancient giant redwood tree in Humboldt County, CA to protest and draw attention to the mismanagement of old-growth timberland. On December 15, 1999, she entered into agreement with PALCO (Pacific Lumber Company) that the redwood (variously known as "the Stafford Giant", to locals, and "Luna", to Julia and her Earth First! supporters) and the ecosystem in which it grows (about 3 acres), shall be protected and preserved in perpetuity.
Julia spent most of those two years perched at least 180 feet above the forest floor, enduring harrassment from Pacific Lumber employees, surviving El Nino storms, giving interviews and contributing to the Earth First! cause.
