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.

Treeline

In this film, two people and two worlds meet. Craig DeMartino, an adaptive climber from Boulder (Colorado) and Kai Lin, an industrial engineer from Brooklyn (New York) team up to design a game-changing prosthetic foot. This is easier said than done. Early prototypes don't hold up to the rigors of straight-in crack climbing, but this unlikely alliance is determined to test the power of problem-solving, so Craig and Lin keep at it.
