That was fun to watch!
We were at Crested Butte during the Freeskiing Championships in February. It is AMAZING to watch in person, because you see the entire line they ski, and you can see exactly how technical and steep the terrain is. The finals were in the Hourglass, an area in the Extreme Limits terrain that is closed to the public. The entire area is cliffs, no wide-open sections till the very bottom. Jaw-dropping stuff.
