West of Sliver Creek, to the west of Cooke City a skier triggered a soft slab avalanche that was wind-loaded with the storm snow. The slide was south facing at 9,000 feet at an abrupt change in the angle of slope (prob 38-40 degrees). Nobody was caught. Crown was 50-60 cm, and propagated out to the adjoining slope,150' wide and 300' long. Photo: Anon
