Wrangelled. It's not a trailer, it's a mooooovie.
Artful short ski mountaineering film shot in the Wrangell St. Elias National Park in Alaska,in April of 2013. Looks like the skiers and crew were flown in in little planes, rather than helicopters. Good on Arc'teryx for supporting this kind of endeavour. This trip looks like one heck of an adventure and a great way to experience the environment.
