Primary Problem: Wind Slab
Bottom Line: Strong wind today will create fresh slabs that are easy to trigger, making human-triggered wind slab avalanches likely. On non-wind-loaded slopes loose snow avalanches are possible and can run long distances on the crust below the recent snow. Be cautious and avoid wind-loaded slopes today. Watch for a textured or pillowy snow surface, or cracking out from your feet or skis as signs of wind-loading.

From obs: "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."

We also received reports from another group (IG story video) that triggered a couple similar sized wind slab avalanches in north facing chutes in Frazier Basin.

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.

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'.

  • 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

  • Winds have worked over many slopes near the Throne. We found some slopes stripped nearly to dirt with the snow blown off to who knows where, and others had wind-sculpted sastrugi. Trees were broken off, and debris littered the snow surface. Photo: GNFAC

  • We triggered a small soft slab avalanche on a south facing aspect around 7800'. This avalanche broke in a wind drift, 4" deep in low density new snow, likely on a sun crust or near-surface facets. Photo: GNFAC

  • On 01/08 my partner and I skied into Frazier basin in the northern Bridgers, we skied the love chutes east down and overall the descent was pretty wind hammered from a downward wind. Once at the lake we took the Frazier return route where we found much better ski conditions in the corridor and decided to lap some of the features. We ended up triggering a small wind slab at around 8k on a NE aspect that broke about a foot deep and ran about 25 yards. Very dense wind slabs were forming on a lot of the aspects getting out of Frazier and we opted to not test our luck any further for the day.
