POV of Denali Messner Avalanche

The poster's description pretty much says it all:

"Avalanche starts at 5:06. At 5:34 I turn my skis left and start to make pressure with my edges (to avoid flying over the bergschrund). At 5:55 I manage to come out the side of the avalanche. Injuries: Not a scratch, just broke a whippet."

As, look very carefully at the start of the avalanche, at around 5:10, and you can see the broken-up slab.
