Primary Problem: Wind Slab
Bottom Line: Assess the stability of the new snow as you travel and watch for changing conditions throughout the day. Be cautious of steep slopes with fresh drifts or a moist snow surface. Cracking across the snow surface is a sign fresh drifts are unstable, and roller-balls or pinwheels indicate a moist snow surface and increasing potential for wet loose slides. Avalanches might not be huge, but even small slides can be harmful if they knock you over a cliff or drag you into trees or rocks. Before riding steep slopes consider the consequences of being caught in any size slide.

Fairy Lake
L-AS-R1-D1.5-S
Elevation: 8,400
Coordinates: 45.9043, -110.9580
Caught: 0 ; Buried: 0

Skied the north chutes above fairy lake around 8,400 ft. Found 8-12" of new snow, with the bottom 2" consisting of large graupel. In steep terrain our sluff entrained lots of snow making for some large debris piles. Overall the snow was generally well bonded.

The skiing was good and non reactive on the main East face next to the skin track. The North gullies into Naya Nuki creek and the the lower/steeper gullies to the south were highly reactive and entraining lots of snow.

Elevation: 8,500
Aspect: NE
Coordinates: 45.8586, -110.9560
Caught: 0 ; Buried: 0

Skied the Banana today with 8-12” of new snow that has mostly bonded. The snowpack below the new snow had froze over night and was well consolidated. 

Observed a layer of graupel (3-4mm grains) at the new/old interface on the NE ramp starting at 8600’ and clearing up after 8700’.  This layer created some reactivity in the storm snow.
Wind slabs <6” had formed on N and NE aspects. We had one small release in the bottom of the couloir measuring ~10x20’ and running ~50’.

  • There were a number of wet loose avalanches in Airplane Bowl. All on E/S aspects near rocks or cliffs. Most were relatively small and had not entrained much snow from the surface or gouged deeper than a few inches. Photo: GNFAC

    We need your input! Eastern Oregon University is conducting a survey to better understand avalanche safety preparedness among motorized backcountry users like you. Your feedback will help us learn more about who is purchasing and practicing with avalanche rescue gear (beacon, probe, shovel) and participating in avalanche education—and why some riders aren’t.  The survey is confidential and anonymous.

    Thank you for your time and for being a part of this important effort!

  • We skied past a wet loose avalanche that came off of the south face of Bradley‘s Meadow. It was slightly bigger than the rest of the wet snow activity that I observed during the day. Photo: GNFAC

  • The snow ranger crew was riding around the Bridgers today and we spotted this slide in the bowl to the south of Hardscrabble peak.  It looked fairly recent (last 2 days) but a little hard to tell due to the new snow since yesterday and blowing snow today.  Photo: USFS Snow Rangers

     

  • As we neared the ridgeline and shifted to a more southerly aspect, we noted scalloped and scoured snow surfaces and the development of thin wind skins and a few 1-2" wind slabs. Photo: GNFAC

  • Mar 15 Winds in the Frazier Basin zone were stronger than expected with moderate to strong gusts at the ridge, increasing through the day. We noticed two large windslab pockets that had released since yesterday’s snow. One at the base of Hardscrabble Peak on a N aspect, the other in one of the SE facing gullies that access the Peak 9299/Hollywood Headwall ridge (see photo).

  • Skier triggered wind slab on Northeast slope at 7,450 feet elevation. One skier was caught and carried roughly 10 feet before the slide came to a stop.

  • Mar 7 obs: "...There was 6" of low density snow from yesterday. Winds were stronger than expected, from the north at the top of the Throne, and increased through the morning.... We found fresh drifts that were reactive, cracking easily and 5-10' wide out from our skis, on south and east facing slopes around 8000-8300'." Photo: GNFAC

  • Mar 7 obs: "There was 6" of low density snow from yesterday.... The new snow was low density and sluffed easily on steep shady northerlies. On steep slopes facing the sun (south and east, and probably west) the new snow sat on a crust and became moist as the sun warmed it up and started to slide under skis. We saw a couple very small natural loose snow slides below rock outcrops on south facing slopes. Air temperatures were well below freezing, especially with wind chill, but the sun quickly warmed the recent new snow." Photo: GNFAC

  • From obs on 3/4/25:

    "Saw a few sluffs in the new snow triggered by skiers in the very steep terrain just north of the Bridger Bowl ski area boundary (see photo). These sluffs were small, definitely not large enough to bury someone."

  • Observed multiple wet loose slides naturally triggering and running on south facing slopes beyond bradleys and on the south facing aspects of hourglass chute.

  • From obs.: "Saw a recent cornice triggered wind slab off of Hardscrabble Peak, crown looked fairly fresh. There was a second crown line below the rock band. Conditions were very windy, with snow still being transported. Most snow surfaces were wind affected, but saw no cracking or collapsing." Photo: F. Miller

  • Skiers triggered a medium sized cornice fall that triggered a dry loose (sluff) avalanche that created large powder cloud.

  • Toured out to Frazier Basin and turned around seeing widespread avalanches and active wind loading. Despite our pits on the Throne the day before showing no weak layers, the amount of wind loading and potential for slabs over density changes gave us pause. Good skiing and sledding down low.

  • On a cold day we rode to Frazier Basin and quickly answered the question, “Are wind slab avalanches still possible or have they stabilized?” We saw a natural avalanche (R2, D1.5) that released on a steep headwall just to the south (I believe I’ve heard this referred to as October Bowl).

  • Feb 7 We saw a couple storm slabs that broke in today's snow 4-6" deep, 10-30' wide, and we triggered one 3-4" deep wind slab, "remotely", from a few feet back on a small ridgeline. R2-D1. These slabs were very soft, F- to F hard. Photo: GNFAC

  • In the Playground area of the Bridger Range, strong winds rapidly built wind slabs up to 25 cm deep around treeline. Skiers experienced a few cracks in this wind slab, propagating 2 or 3 meters from our ski tips. Photo: N. deLeeuw
