Trees are the oldest living beings we come to know during our time on earth. Moreover, trees are always beautiful. Patagonia’s latest documentary, Treeline, is a lovely documentary about trees. The documentary explores our relationship with the planet’s oldest living things, trees through the eyes of a group of skiers, snowboarders, scientists, and healers to the birch forests of Japan, the red cedars of British Columbia, and the bristlecones of Nevada.
