Report of a skier triggered avalanche in Grizzly couloir.

This is a third hand report. "Skied the rolls on little sifton today, touch of wind on it but no reactivity. Ski cut about 2m in from the entrance to Grizzly Couloir, and the whole thing ripped (except for the rocky stuff on skiers right) sz 2.5. Crown at the top was about 20 deep, some of the sidewalls it tore down lower down fractured more like 40 deep. All new, soft wind slab from the HN24 (cold stuff at the end of the storm). Wasn’t surprised to get something to pop, but it propagated well and definitely went bigger than expected. A couple smaller, similar depth slides out from the shit that always rips into Grizzly bowl from the top of teddy bear / FF area, one of which also propagated quite wide for its depth."
