Party of 2 went to ski the pillows skiers left of the dog leg couloir on the N face of Glacier Crest on Feb 10. About halfway down the face, we kicked off a storm slab over a steep, unsupported rollover. The slab cracked ~20m across and 1m deep. It ran out about 5m down to another bench below, but would have run much further without the terrain undulation. Seemed to be a storm slab resting on the late January crust. Nobody was caught.
We observed the same slab had cracked off, triggered by skiers on top of the ridge, on the N side of the glacial moraine below the runout of the couloir. It was propagating as far across as the face would allow, and ran the entire length of the face to the valley bottom. Be careful out there!
