Avalanche Details

First a comment on the snow pack. There is a crust with some powder on top. These are No-telemark conditions. The snow is very noisy because of the crust. If you fall while hiking and your shirt sleeves are up, you will receive a rash on your arms from the ice.
Often the fresh snow will sluff on the crust layer and gradually gain speed and mass.
The avalanche I caused was not a sluff and propagated and had a crown. Then it collected all the powder on the crust and gained significant force.
We suspected a change in the snow pack while skinning and sure enough the adjacent slope slide while skiing.
The other ski runs we did did not cause avalanche and there where only a very few other people.
