Not the "right" way to handle steep terrain, but it is certainly a way to manage it in "survival mode". Basically, all he was doing was sideslipping the whole way down. He would side slip on the heel edge, pop 180 and side slip on the toe edge. Not really making any turns. At the entrance to the chute, totally understandable, but when it opened up, there was no reason not to make decent turns; that pitch wasnt that bad and the snow conditions looked pretty good. Not dissing the guy`s riding, but a more advanced rider used to steep terrain could have made some good turns on most of that.
I have to ask, WHY is that guy riding that terrain? It seems almost straight down. I can only imagine that the only way that would be enjoyable would be if there was about 3' of powder to ride through lol. Otherwise, maybe to say "hey I went down that" but ...didja really? One might as well take their board off and slide down with an icepick in one hand...just saying.
This goes back to an earlier post of mine. Riding down nice powder covered blacks, only to have them turn into a mogul field 2 hour laters because, people that have NO right on being on those steeps create those moguls from making very sharp dynamic turns on skis to avoid the speed. Well, then why not ski blues and leave the terrain at least somewhat rideable, or at least make wide turns!
