Bottom Line: Moderate winds out of the northwest to west will form fresh drifts of snow that can avalanche under the weight of a person. Avoid wind-loaded slopes if you see signs of unstable fresh drifts such as wind transporting snow across ridgelines, cracking across the snow surface or fresh avalanches. If other signs of instability are not present, before riding steep slopes dig and do a quick stability test to look for unstable weak layers buried below the recent snow.
Primary Problem: Wind-Drifted Snow

  • From obs: 01/01/22: "Saw a small slide come off the ridge. We dug a pit and the wind slab was 8 inches to a foot and a half. During our snow tests it consistently broke on the week layer around a foot deep." Photo: B. Paulson

  • From obs 1/1/22: "While skinning towards the ramp we witnessed what looked like a natural slide that started right around Pete’s Pinnacle which ran down along the boundary line about 1000 feet. Unknown trigger."

  • Strong ridgetop winds transported snow onto Saddle Peak creating unstable slabs on January 1st. Photo: GNFAC

  • Strong winds on 1/1/2022 formed fresh, soft drifts. These drifts broke and cracked easily, and slid on steep slopes. Photo: GNFAC

  • We saw this natural avalanche on the north summit of Saddle Peak on 1/1/2022. It is one of at least 4 natural avalanches that broke on wind-loaded slopes on Saddle Peak in the past 3-4 days. Recent snow and wind formed slabs over weak facets which makes large avalanches possible to trigger.

  • We intentionally triggered this 6-8" deep wind slab on Saddle Peak on December 23, 2021, E aspect at 9,000'. It showed us that recently formed wind slabs were still reactive. This hard slab formed over low density new snow which made it unstable. While not large, these slides will easily push you down and can be harmful if they push you into hazardous obstacles or terrain traps. Photo: GNFAC

  • On December 23, 2021 we went out to Saddle Peak and dug three snowpits. We found a 2-3 foot deep, generally stable snowpack with a lack of unstable buried weak layers. Photo: GNFAC

  • Cornices that formed mid-slope, indicating recent heavy wind-loading in the Bridger Range. Strong southwest wind between 12/18 and 12/19/21 drifted recent snow into hard, pillowy drifts. We avoided these drifts on steep slopes to give them a day or two to stabilize. Photo: GNFAC

  • These pillowy, hard drifts formed from strong southwest wind overnight between 12/18 and 12/19/21 in the Bridger Range. We saw minimal signs of instability, lke whumphing or cracking in these drifts, but avoided these features on steep slopes until they have more time to gain stability. Photo: GNFAC

  • On 12/16/21 A skier in a group of three triggered and was caught in this avalanche next to The Apron at Bridger Bowl. The ski area is closed and backcountry conditions exist. Nobody was injured.

    From e-mail: "We had a group of three skiing up at the Bridger Apron today. We skied a more main slope in the field north of the slope with hidden couloir, snow was very stable and has been getting a lot of tracks. For a second run we skinned up the main slope under hidden and started our run in the trees slightly south of this slope. Not many tracks over there and not a good enough evaluation of the snowpack. We were planning on skiing a northeast facing chute through the trees that had very nice looking snow similar to what we had skiied earlier. I skiied in and had about 3 amazing turns, definitely partially due to the wind loading at this aspect. After three turns my feet were taking out from under me and I got caught in a slide keeping skis perpendicular to slope for 15-20’. This avalanche carried me rapidly and cleared the snow to the rocks below in which I was able to come to a hault and watch the rest of the sluff slide past me. After looking at the conditions after, this windy aspect seemed to have a very faceted layer about 8” down that acted as the crown. No injuries, a lost ski pole in the runout which extended down the slope maybe another 40’. The wind scoop on top and seeing these facets should have been a clear sign prior to skiing. Must be more diligent even in areas of high traffic. When dropping in to ski on first turn or so I remember hearing a possible whumpf."

  • From obs: 12/12/21: "Shooting cracks and whoomphing in wind loaded areas. An approximately 15x30ft wind slab cracked along the base of a rock band and settled at the base of P2 on high fidelity. Was triggered while traversing along the rock band to gain the second pitch, 1-2 inches of facets on the ground. Wind slab of 6-36in in the gullies." Photo: M. Hearley

  • In the Bridger Range on December 10, 2021 2-3" of low density new snow was drifted into small soft slabs that were easy to trigger. Photo: GNFAC

  • This pit was dug in Hyalite Canyon near Twin Falls. It showed 2 mm facets (sugar snow) underlying the snowpack. This layer did not break in stability tests, but anticipate these grains will get weaker with time. Photo: GNFAC

  • For the Bozeman Ice Fest we investigated the Silken Falls and Avalanche Gulch gulleys. They were wind-loaded and had weak snow mid-pack that was unreactive. Avalanches in these gulleys would be deadly, so be extra vigilant in your assessment before crossing. Photo: GNFAC

  • We found 80 cm (2+ feet) of snow on a NE facing slope at 8,000 feet outside Bridger Bowl's Boundaries. The snow was supportable with a weak layer at the blue card. Faceted, weak, sugary snow is the layer of concern, but it was not that bad...yet. We'll be watching to see if it gets weaker. Photo: GNFAC

  • Monday night's new snow formed wind slabs from the strong wind on Tuesday. We are finding these throughout southwest Montana. Photo: D. Britt

  • New snow was blown into thick drifts that can be triggered by skiers or riders. Cracking like this is a sign that drifts are unstable and could slide on steeper slopes. Photo: GNFAC
