  • Cornices have grown large along ridgelines and could be easy to trigger. Stay far back from the edge and avoid or minimize time on slopes below. Slopes below cornices are likely places to trigger a wind slab avalanche. Photo: B. VandenBos

  • Surface hoar and near surface facets (weak layers) are forming in the Bridger Range, and probably other ranges, during cold temperatures and clear nights. Photo: GNFAC

  • 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

  • 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

  • A recent avalanche near Cooke City. "SE aspect, around 10,000' (just south of Mt. Zimmer). Estimated 2' deep and 30' wide." Photo: B. Fredlund
