  • 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

  • Blue skies, snow capped peaks, and above average temps made for a perfect day to put up the Lionhead weather station. View the data here:

  • Info and schedule:

    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
