This slide an one other occurred on a NE aspect of Mt Henderson above the Fisher Creek near Cooke City. Notice the ski pole to gauge depth of the avalanche. These slides broke over 3 feet deep on weak facets near the ground. One slide was 300 feet wide and the other was about 100 feet wide. At least one was human triggered. Photo: B. Fredlund
