Explorers Shawn Forry and Justin Lichter completed the first ever winter expedition of America’s 2,650-mile Pacific Crest Trail from Canada to Mexico. They faced Arctic-like, subzero conditions in the High Sierra, extreme winds and overcame frostbite while traversing in snowshoes, skis and boots with crampons. Utilizing ultra-light techniques, they covered more than 20 miles per day and went more than 1700 miles without seeing another person on trail. They completed the trek in 132 days, faster than many complete the PCT in the summer. Inspired by the legendary John Muir and native ancestors who walked this land before them, the team documented their observations of a changing landscape amidst an historic drought and sought to better understand humanity’s role in protecting the planet for future generations.
