And Bob R's video Glissading from Trail Crest:



Note: Everyone BEWARE! People have died attempting to glissade on Mt. Whitney! Here are some guidelines:

1. Never glissade wearing crampons. (see BobR's x-ray)

2. Never glissade without an ice axe for a brake.

3. On Mt. Whitney, the top of the slope can be soft, but iced-up below, since the afternoon sun shadow starts at the bottom and moves up. So late afternoon can be treacherous.

4. Learn and practice self-arrest techniques and glissading before trying to glissade from Trail Crest on Mt. Whitney.
