Trorey Glacier

Entered slope from above a cornice, sliding into the slope through a gap in the cornices on the ridge above the Trorey Glacier. The first skier in experienced some loose sluff which ran about 80m downslope. The third skier as they entered triggered a windslab under the steep part of the cornice which propagated about 10m but to skiers right of the line we were skiing, so the skier wasn't affected, this slid about 30-40m.
