"On December 10, 1997, Julia Hill ascended 180 feet (55 m) the redwood tree Luna. (...) Hill lived on two 6-by-6-foot (1.8 by 1.8 m) 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 attempted intimidation by angry loggers."

A culturally modified tree.
This tree was discovered and used by the First Nations of Flores Island over 150 years ago. It was rediscovered in 1994 during a culturally modified tree survey. Two planks or boards have been removed. The small chop marks indicate where there is a hole in this tree, this tree was also 'tested' to see if the wood was of high enough quality to make a good canoe. It did not pass the test. - Stanley Sam Sr. of the Ahousaht First Nations, Ahousaht Wild Side Heritage Trail Guidebook .
