Comments
This looks to be a remotely triggered avalanche from over the weekend. We are assuming that it was remotely triggered due to the lack of the natural activity in the area. It was also clear that this released after the windy December 12th storm. There were sled tracks at the bottom of the slope as well as tracks on the sides, which leads us to believe that it was a remotely triggered avalanche (meaning triggered from the flats or adjacent to the slope). The avalanche and sled tracks looked to be very similar in age which also pointed to this being sled triggered. This avalanche failed on sugar snow near the ground.
