Natural avalanche events in the Bridger-Teton National Forest backcountry
Some days the steep slopes are safe, some days they are unstable. 90% of avalanche victims die in slides triggered by themselves or a member of their group. More people are killed during Considerable Avalanche Danger than any other Danger Rating. After 35 minutes, a buried victim has only a 27% chance of survival. The American Avalanche Association recommends all backcountry users take an avalanche safety course taught by a Certified Instructor.
