Snowpack and Avalanche Discussion
Bridger Range Madison Range Gallatin Range
Lionhead area near West Yellowstone Cooke City
This snowpack in the 3rd Yellowmule off Buck Ridge was 100 cm's deep on a north facing slope at 9,200 ft. The layer of concern is a well developed layer of facets sitting over an ice crust just under a foot off the ground. This layer will remain a concern for some time. Photo GNFAC

Snowpack and Avalanche Discussion
Bridger Range
The Bridger Range is favored by certain weather patterns. A west-southwest flow is not one of them. Although the Bridger Range squeezed out 4-5” of snow overnight, I don’t expect snowfall to continue through the day. This fresh coat will improve conditions for opening weekend at Bridger Bowl, but I don’t expect it to drastically increase the avalanche danger.
