The small photo on the left was a small avalanche triggered remotely which is a prime indication of unstable conditions. The natural avalanche in the photo on the right was spotted later in the same area. In the past 72 hours, the Cooke City area has received 4inches of SWE (about 4ft of snow). Photo: B. Fredlund
