Bottom Line: Above freezing temperatures and rain on mid to low elevation slopes will create potentially unstable conditions in steep terrain.

Photos- Northern Madison

  • The lack of freezing temperatures created wet slides in Beehive Basin. These slides occurred on a west facing slope around 8,500 ft. Photo S. Knowles  

  • High elevation slopes that were heavily wind-loaded (N-E) avalanched with explosives during control work. Crowns were near 3 feet deep and the slides broke at the ground. Photo: BSSP

  • Gusty, intermittent winds from the SW blew in Hyalite yesterday and formed windslabs of variable thickness. These small, stiff, slabs were reactive to ski cuts. Photo: G. Antonioli

  • 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

  • Cornices in Beehive basin were growing in size and sensitivity throughout the day. This cornice failed naturally which triggered as small wind slab on the slope below. With more snow and wind in the forecast, cornices and wind slabs will remain an ongoing problem. Photo: G. Antonioli 

  • Strong winds on Thursday (11/16) were blowing new snow and forming wind slabs in Beehive Basin. Photo: G. Antonioli

  • Skiers at Bridger Bowl noted that above the base of Alpine and Powder Park lifts, there was surface hoar covering just about everything that hadn't been groomed. Photo: S. Ranney

  • Feathery crystals of surface hoar were seen near Palisades Falls in Hyalite. This is not widespread or a current concern, but there's nothing more beautiful than a crisp picture of surface hoar. Photo: M. Santana

  • 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

  • This slide on Saddle Peak occurred during or shortly after the storm on Nov. 3rd-4th. The slope appears to be wind loaded and the slide was likely triggered by a cornice fall. Photo: GNFAC   

  • Two skiers took this picture skinning up the Fairy Lake Road in the Bridger Range. Wind had been moving lots of snow around; pretty active loading on ridge tops as well as lower elevation spots. The lower hills surrounding the approach to Ainger Basin from the road were heavily loaded as well. Photo: G. Antonioli
     
  • Climbers wallowed across soft, powdery snow up Flanders Creek in Hyalite looking for ice to climb. The snow was not layered and it easily sluffed off.Photo: M. Hopkins

  • This crown lines were observed on Mt Blackmore in the northern Gallatin Range. These slides occurred on NE facing slopes around 10,000 ft. and were the result of new snow and wind loading. Photo B. Vandenbos

  • Skiers on Mt Blackmore in the northern Gallatin Range observed these natural avalanches on a NE facing slope. The slides were a result of new snow and wind loading. Photo B. Vandenbos

  • This snowpit was dug near the top of the Apron at Bridger Bowl. The stability test score of ECT 9 means it propogated all the way across and slid quickly on the 9th tap. The weak layer was 30 cm from the surface in a 90cm snowpack. The interface between the old/new snow may remain unstable through the weekend, especially with wind-loading. Photo: Roy Taylor

  • 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

  • A photo of the crown and slope that was skier triggered in Sacajewea Bowl yesterday (Oct. 3). Slope was 47 degrees steep (!), NE aspect and the crown was 40 cm thick out of 115cm total snowdepth. Photo: K. Birkeland

  • From M. Lavery: "Went for a short tour up towards Sacagawea yesterday afternoon from Fairy Lake. There was a skier triggered slide in the bowl just north of the summer hiking trail. Crown is just below the rocks up near the ridgeline. Lots of signs of wind loading in the new snow from the past few days. There were a few other small skier triggered slides in the area as well."

  • 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
