Bridger Range, 2020-12-24 Natural avalanches on Bridger Peak observed at 1200 on 12/24/20. These occurred within the last 24 hours after the area had 8-12" of snow (.3-.5" SWE) and strong winds. Weak sugary snow on the ground failed under the weight of fresh slabs. This activity is a sign that the snowpack has a poor structure that will struggle to support future storms.
