Southern Madison, 2023-04-04 Overall seemed like a deep HS (220 cm) versus other years I’ve seen here. High strength in pit (ECTP26), failure on facets below melt-freeze crust down 60 cm, and with no more obvious signs of instability. Felt weak snow deeper, but only dug in the top meter. North winds increasing throughout the day and any wind affected snow was shallow in depth. South aspects were crusted but protected N-facing or tree skiing was still great. |

Island Park, 2023-04-04 From obs: "On Sunday morning, the sun broke through for a bit and allowed us to view the widespread avalanche cycle that occurred overnight on all aspects. Across the creek, we saw a large crown (approx 3’ in depth) in the meadows. An avalanche that occurred on Nemesis’s south face ran from mid-mountain all the way into Hellroaring Creek, running over our old skin track." Photo: Eric and Melissa Link to Avalanche Details |

Lionhead Range, 2023-04-03 There was a large natural avalanche that broke yesterday on Bald Peak it was bounded laterally by the terrain, so it only broke a couple of hundred feet across, but it appeared to be 4-6' deep and ran the full available vertical into the creek below. This avalanche was the key piece of information for the day and answered the question of whether or not the snowpack is continuing to produce deep slab avalanches with every storm, it is.

Lionhead Range, 2023-04-03 We saw three more avalanches that broke at least a few feet deep and several storm slab avalanches that failed within the new and wind-drifted snow. Photo: GNFAC Link to Avalanche Details |

Cooke City, 2023-04-03 From IG: “Wanted to touch base about an avalanche we triggered on the shoulder of Mineral Mountain today. While skinning up there was obvious wind loading coming from the south. I kicked around a bit near the edge of the ridge (no cornice) and remote triggered this slide from 20’ away. It broke 12-18” deep, and propagated 700-800’ wide. Ran full length of the slope into old growth trees 1200’ below. Would estimate R4 D3. We found good stable skiing on the south aspect (~35°)” Link to Avalanche Details |

Cooke City, 2023-04-02 Skiers in the Republic Creek drainage saw a fresh natural avalanche on Woody Ridge. The avalanche occurred on a NW aspect, around 9200' (likely last night). Estimated size: 1-3' deep and about 100' wide. Photo: B. Fredlund Link to Avalanche Details |

Cooke City, 2023-04-02 From email: "Saw this very large avalanche on Climax. The crown looks fresh, so it likely occurred the day or night of 4/1? |
