Thanks for posting the video. I enjoyed it, and I love glissading safely. The glissader, in my opinion, did do it safely and was in no danger. The way he did it is fun and exhilirating--the way it should be. He slid down an existing glissade track, that even though it appeared to at first head right into the rocks in the distance, it skirted to the viewer's right. He obviously knew how to use his ice axe to control his slide and stopped when he felt he needed to.
