Corbet’s Couloir at Jackson Hole, WY is probably one of the most iconic extreme lines in North America, if not the world. In 2012, Teton Gravity Research and KGB Productions were at Corbet’s on a sunny post-pow day for an all-time Corbet’s session. From over-under airs to big senders to a 14 year old boosting the entire entrance, it was classic Jackson Hole.
