Northern Gallatin, 2019-03-04 From e-mail: "Observed a small slide that appeared to be skier-triggered (tracks entering & exiting) on a wind-loaded, north-facing (21 degrees north) slope, slope angle of approximately 36 degrees." Photo: A. Yount Link to Avalanche Details |

Northern Gallatin, 2019-03-04 This crown was observed on 3/3 and likely slid a couple days earlier after steady snowfall and wind. This path had a large avalanche previously this winter in mid-January. Photo: G. Antonioli Link to Avalanche Details |

Northern Gallatin, 2019-03-04 Steady snowfall last week created soft slabs like this natural crown. Photo: G. Antonioli Link to Avalanche Details |

Northern Gallatin, 2019-03-04 Cornices are large, and intense spring sun will make them weak and easier to trigger or break naturally. Be cautious along ridgelines and on slopes below these monsters as temperatures warm. Photo: G. Antonioli Link to Avalanche Details |

Northern Gallatin, 2019-03-04 Loose snow slides are possible on sunny slopes during intense spring sunshine. Recent snow is unconsolidated and it may be easy to trigger loose slides on some steep slopes. Photo: G. Antonioli Link to Avalanche Details |

Northern Madison, 2019-03-04 "The YC Ski Patrol conducted avalanche mitigation work above another one of our roads today. The area is outside of our ski area boundary and receives no skier traffic. A 4lb explosives charge was detonated from an aerial tram and triggered a R2/D2 avalanche that ran to the ground. The crown was 2', the path width was around 100', and it ran 350 vertical feet (crossing the road) to the bottom of the runout zone. The elevation was 7280' on a NNW aspect and max slope angle of 34 degrees. Other sections of this slope were tested with explosive charges, yielding only black holes."
