I have not, but when I saw the above video, I immediately remembered a video of a really long run from the top to the Telluride valley I saw on a Sierra-related site. The place has been on my long list of possible places to visit since watching this - 3800 feet in 9 minutes (my local hill is 180 feet and less than 30 seconds


same site has the report on his Whitney North Face ski descent - not many who can say they have done that, given there's rarely enough snow to make that even remotely possible.
