X Games Gold Medalist, Jossi Wells, steps out of the park and into the Mammoth backcountry with Chris Benchetler for the "The Sierra Trifecta," skiing, climbing and biking - all in one day.

In this final episode of Chasing El Niño, Chris and his ski crew hike 6,000 vertical feet through rock fields to find the last of this season’s snow in the Sierras.

From deep powder in January to spring slush in May, Chris documented a skier’s dream winter by chasing the best storms around North America. To watch his full journey during the 2015-16 season, click on the following links below.
