Comments
Triggered a first avalanche on the second skier, over a windslab. First avalanche (size 1) went down 30m and triggered another larger avalanche (step down on lower layer). Larger avalanche (size 2.5) ran all the way down the bowl. Average inclinaison was between 35-45 degree. No buried or injured people. One skier (the first one) almost got caught but escaped from the avalanche path when second avalanche was triggered.
