I was out winter mountaineering (snowshoeing) with client today in the Cerise Creek zone and notice this small slab on the west side of Vantage. When we arrived at the hut it was -18 and winds were blowing at ridge top. We when in for a cup of warm tea and a small rest before heading up cabin ridge and back to truck. I spoke to the folks that were leaving the cabin. Turns out the group (from Seattle) were skiing that run late yesterday (4pm Jan. 1st) the 8th skier when down and cut far left to get fresh turns. They was no skier affected by the slide. He was not aware of the slide till they all looked back. Stubborn slab!
