It was a cold and windy day on the PC ridgeline but the new snow skied very well where ever it was deep enough. New snow depth varied from 8-12 inches in the West Monitor and McDonald Draw areas. There were several naturals already present on West Monitor when I arrived. The picture from the top shows a sluff that ran when I approached the cornice. After running about 50 feet at a convex rocky area the the new snow slab fractured about 30 wide and continued to run at a moderate speed to near the base. I was also able to get 2 other sluffs to run to the base with moderate speed by way of a ski cut and a small cornice drop.
