Description
A party of three were skiing on a south-facing slope on Mt Hector in Banff National Park. A slab avalanche approximately 80 m wide was triggered. The crown tapered dramatically along the crest of the ridge from nearly 2 m in heavily wind-loaded drifts to as little as 40 cm. The avalanche ran for approximately 550 m and caught one person who was deeply buried by the debris. The victim was extricated by companion rescue and airlifted to hospital. She succumbed to her injuries and died the following day.

Commentaire sur le manteau neigeux: The avalanche ran on a weak layer of facets and depth hoar near the base of the snowpack. The avalanche caused most of the snow to be removed from along its path, exposing the ground and scrubby trees in many places.
