Went down to American Fork Canyon to ski and got some good views of the east faces Box Elder. I suppose I can confirm suspicions that an avalanche cycle occurred down there. I remember seeing at least five avalanches mostly in the 1-2 feet deep range three of the avalanches were on Box Elder and the other two were on nearby terrain. In the photo I drew in two of the avalanches. The one on the right side of the photo was the biggest I saw. There was also a crown across the top of the shotgun chutes that you cannot see in this photo.
