In August & September 1996, 1997 and 1998 he attempted to ski down Everest's North Face, but due to the constant monsoon weather was never able to reach the summit. Unfortunately the best time to ski Everest from its summit is during the monsoon season, thus why the prize of skiing Everest from its summit has been elusive. http://classic.mountainzone.com/climbing/skieverest/updates.html]
