Lionhead Range, 2022-02-10 Chris Hericks, snow ranger on Beaverhead Deerlodge NF, points to the lower of two surface hoar layers. We are finding similar layering throughout our entire forecast area. The top 18" of the snowpack is weak and will quickly become unstable when it snows. Photo: GNFAC |

Cooke City, 2022-02-08 A group of riders snapped a photo of this avalanche on Sunday. The slide isn't huge but it would be highly consequential in the treed terrain were trauma is a real possibility. Photo: A. Bertolino Link to Avalanche Details |

Cooke City, 2022-02-08 A group of snowmobilers reported triggering this small avalanche from the backside of the rollover on Sunday. Triggering an avalanche from a long distance away is a clear sign of an unstable snowpack. Photo: A. Bertolino Link to Avalanche Details |

Cooke City, 2022-02-07 From Obs: "On the morning of Sunday February 6, a snowmobiler triggered a slide in new snow on the SW face of Sheep Mountain. The slide triggered remotely while the rider was lower on the slope and he was not caught (the visible track is not from the rider who triggered the slide, his track was buried in the debris field). The crown was about 18" deep and 75 feet wide and the slide and the slide ran about 250 feet." Photo: C Mozol Link to Avalanche Details |
