Bridger patrol triggered deep slab avalanche 2

This slide was triggered by Bridger Bowl ski patrol during control work on Saturday (1/4/2020). It shows deeply buried persistent weak layers from early October and November were pushed to a breaking point by the recent snow and wind. A person can trigger avalanches like this on heavily wind loaded slopes in the backcountry. Additionally, shallower large avalanches can be triggered on any steep slope. Photo: BBSP
