Corbet’s Couloir is the most famous and hardest run at Jackson Hole in Wyoming.  It is one of the few slopes to have its own wikipedia article! Here are some highlights:

“Currently rated #4 on the top fifty things for skiers to do before they die, it holds an international reputation among expert skiers, and has been described as “America’s scariest ski slope”

“Entrance into the couloir requires dropping off a cornice with a free fall ranging from 10 to 30 feet (9.1 m) depending upon snow conditions, landing on a 60 plus degree slope.”

So it’s pretty hard. In this ski video, we see the guy skiing up to the ski run, past a big “CLOSED” sign. They chill up at the top and watch a guy ski down it nicely. The camera man’s friend then jumps in, doesn’t look too good. We are then informed that he “yard saled” and see him collecting his equipment. Ends up he has an ACL injury, that sucks. Awesome run though!
