Treeline

Quietly, patiently, trees endure. They are the oldest living beings we come to know during our time on earth, living bridges into our planet’s expansive past. Treeline is a film celebrating the forests on which our species has always depended—and around which some skiers and snowboarders etch their entire lives. Follow a group of snow-seekers, scientists and healers as they explore the birch forests of Japan, the redcedars of British Columbia and the bristlecones of Nevada, delving deeper into the rich environments they call home.
