CONT

Sluffs seldom entrain enough snow to bury a person deeply and the chief danger to winter recreationists from this type of avalanche is from being pushed over a cliff or rock band.

CONT

... the [snow] slide quickly picked up velocity and traveled over a rock band (terrain trap) which may also explain the trauma to the fatality.

CONT
