Northern Gallatin, 2024-01-10 From Obs: "While skiing one of our intended slopes, one of my partners skied over a small rollover and as he arrived at the bottom of the small slope a pocket had released above him and stopped just above where he was standing. The culprit was again the recent snow on top of older faceted snow." Photo: Anonymous Link to Avalanche Details |

Northern Madison, 2024-01-10 We then dug on a east-facing slope to the north of the Beehive/Bear cornices and found 105 cm of snow and a 1 foot deep slab that broke in our test as an ECTP3. Low test scores, recent avalanche activity and cracking and collapsing was evidence of the snowpack's instability. Photo: GNFAC

Northern Madison, 2024-01-10 We toured up Tyler's Slope and dug at 9,200' on an west-facing slope. There was a 6" slab of snow sitting on fist hardness facets that propagated in our tests (ECTPV x2). Approaching the pit site we has some collapsing and shooting cracks. Photo: GNFAC

Northern Madison, 2024-01-10 Cornices on the ridge had all broken and pulled out the wind-loaded pockets with one slope sliding 100' distance. These likely occurred last night (1/09/24). Photo: GNFAC Link to Avalanche Details |

Northern Gallatin, 2024-01-09 Seen on a ski tour on 1/08. From Obs: Notice a few natural avalanches and one skier triggered avalanche near of the top of Blackmore. Looked as though it was a ski cut that popped the slab. Photo: S. Lowe Link to Avalanche Details |

Lionhead Range, 2024-01-09 Cornices easily broke while walking near them and avalanched onto the slope below. The slope below had already avalanched from a remote trigger below the ridgeline. Photo: GNFAC Link to Avalanche Details |

Island Park, 2024-01-07 We measured 16" of low-density snow equaling 0.7" of snow water equivalent at higher elevations in the Centennial Mountains of Island Park, ID. The new snow is sitting on a couple of layers of feathery surface hoar and a weak snowpack. It will not take much wind, settlement, or new snow to push the snowpack to the breaking point.
