Several folks have been advising never to glissade from Trail Crest. Now with this video I see why: The slope goes left towards the rocks and this guy was going pretty fast and had to use his ice axe to slow down in perfect conditions! This video gave me the willies just watching it. At one point he yells 'can't stop now if I wanted to!' --if it had been icier....

When the person says "I can't stop now even if I wanted to" he had passed through the steepest area of this run and was in a safe area. He just let it rip like a lot of us do from time to time when there is run out. Also, the conditions were slow...a bunch of slush.
If you don't have clue of how to self arrest or judge conditions you should walk down.
