Plewman avalanche

<p>Looking for a future line off the ridge of Plewman, we accidentally triggered a cornice. The Cornice then triggered a size 2 avalanche running all the way down. Crown was probably 1m+ Deep by ~50m. No one went for a ride. Wind picked up in the afternoon and we could definitely see the snow being transported. We had no sign of instability during the day… Just deep pow. </p>
