In 2011, The North Face assembled an eclectic team of athletes for a ski expedition up Denali, the hulking 20,320-foot mountain that rises from a snow-clad range in Alaska’s interior. The trip, captured in Camp 4 Collective’s film The Denali Experiment, brings together an unexpected mix of new-school talent and mountaineering veterans, matching the likes of Sage Cattabriga-Alosa, the spine-ripping star of ski films by Teton Gravity Research, with experts of the high mountains, such as Conrad Anker and Telluride’s Hilaree O’Neill. The result? The young guns are pushed beyond their comfort zones as they learn what it’s like to suffer for their turns, pushing themselves to physical and mental extremes before getting the glory. And the old hands learn a thing or two about jibbing at 14,000 feet.
