  • Lionhead weather station is up. The early season snow has stuck around most higher elevation, shady slopes, while sunnier slopes have little to no snow. The remaining snow will be the foundation for this winter's snowpack and a layer to keep an eye on. Photo: GNFAC

  • Small wind slabs near the ridgeline and debris piles. Strong wind transported recent snow into drifts in gullies and near ridgelines. Photo: B. VandenBos

  • Snow transported by wind on the headwaters of Lone Mountain cross-loads the gullies with drifts. These drifts can be unstable and slide in steep terrain. Photo: B. VandenBos

  • This pit is next to the avalanche that caught two skiers, resulting in one fatality, on October 7th, 2017. Height of snow in the photo is 120cm (3.5 feet). The hard layer of snow at the top is the layer that slid, and was likely 1-2' deep at the crown where it broke. Photo: GNFAC.

  • Nine search and rescue volunteers, including 2 avalanche dogs, searched the debris for the missing skier. Photo: GNFAC.

  • After dropping of members of the Gallatin County Search and Rescue, the helicopter searches the debris. Photo: GNFAC.

  • The avalanche was in a wind-loaded zone low on the peak (10,100'). It was triggered by 2 skiers as they ascended up the slope. Photo: GNFAC.

  • Info and schedule: http://www.montana.edu/snowscience/workshop/index.html

    Join the GNFAC, MSU, guest speakers, educators, and vendors for the evening.

  • This slide was triggered intentionally from safe terrain above, in the Tobacco Roots (outside our advisory area). The Bridger Range had similar snowfall, and other areas are not far behind on early season snow depth.

    Avoid drifts of snow near ridgelines and steep gullies. These wind slabs will form with more snow and wind, and can be extra harmful with the thin snow cover this time of year.

    Small slides can be harmful or deadly above terrain traps like trees, road-cuts, confined gullies, and creek beds. @splititwithyou
