A group of ski tourers and split boarders were caught in an avalanche in the Cassiope Peak area approximately 17 km northeast of Pemberton. It appears they were ascending when the avalanche was triggered. The slide was estimated at 15-150 cm deep, involved multiple slopes with a combined fracture line of 600-800 metres, and ran 200-300 metres through small trees and over several benches. Two people were uninjured. One suffered serious injuries, and the fourth did not survive.
