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

  • A group at Ernie Miller Ridge had an unstable test score in their second snowpit of the day (1/16/22). Lingering instabilities are isolated but it is an excellent idea to dig down and test the snowpack before getting into avalanche terrain. Photo: T Dumbrovsky

  • A sled was recovered uphill of the 2 avalanche victims in the same area it was stuck. The sled was found with a probe line and is buried 3-4 feet deep. The avalanche crown can be seen in the upper slopes above them. Photo: GNFAC

  • The crown of the avalanche that killed two snowmobilers on December 27, 2021 was 300 feet wide and 4-5 feet deep. Photo: GNFAC

  • These are the two sites where the 2 snowmobilers were recovered. They were buried 4-5 feet deep in debris piles that measured 9 feet deep. Photo: GNFAC

  • Ian Hoyer stands next to the crown where we dug a snowpit and investigated the snow structure. The crown averaged 4-5 feet deep. Near his right knee is the layer of weak faceted snow that broke 40 cm above the ground. Above this layer was a thick slab of windblown snow. Photo: GNFAC

  • Dave Zinn of the GNFAC gets 3 layers breaking in his Extended Column Test. About 3 feet of snow fell in the last 4 days which got blown into wind slabs. The weight of the new snow is also creating instability on a weak layer of sugary facets near the ground. Photo: GNFAC

  • Bare ground on the ridge between Tepee Basin and Bacon Rind Creek. Nearby we found 4 ft deep drifts. 12/22/21. Photo: GNFAC

  • An avalanche in Tepee Basin appears to have failed within or under the new snow around 12/15/21. Photo taken 12/22/21.

  • Natural avalanche in Taylor Fork that broke 100ft wide, 2-3 ft deep, beneath the recent storm snow. Appears to have failed towards the end of the storm (likely 12/15/21). Photo: GNFAC

  • This avalanche was remotely triggered by snowmobilers from over 100 ft away on 12/15. It broke beneath the recent storm snow, 1-2 ft deep.

  • A skier in the Southern Madison Range remotely triggered this avalanche in the Bacon Rind area from a flat bench above the slope. It broke over 50-75' away where the slope got steeper. Human-triggered avalanches are likely. Avoid steep terrain until the snowpack stabilizes. Photo: Anonymous 

  • From obs: 12/12/21: "Heavy wind loading from gusty SW winds and recent snowfall. Made for some touchy conditions. This was at 9100’ between Sage and Sunlight basins." Photo: JR Mooney

  • 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

  • From obs (12/5/21): "Went poking around in the Taylor Hilgard today looking for snow. As expected, found a thin and faceted snowpack at lower elevations. Snowpack improved considerably above 8500', often .5-1m. I dug a quick pit to the ground on a N-NE facing slope at around 9300'. Pit measuded 1.1m, and to my surprise consisted of a relatively compacted and consolidated snowpack, almost entirely 4f hardness. I was expecting to find layers of facets near the base of the snowpack, and between crusts in the middle, but did not."

  • From e-mail 11/7/21: "...Once in airplane bowl we saw multiple large slides that ran last night, syn-storm. Most of which came down from the East face of Sac. A few 200-300’ wide and running the length of the bowl.,,, attached is a grainy cell phone pic of the slides in Airplane Bowl." -Anonymous.

  • From email 11/4/21: "...noticed two small wet loose avalanches in the east facing bowl between Pomp and Hardscrabble Peaks." Photo: H. Darby

  • From e-mail 11/4/21: "Hiking up in the Bridger Range from Sacagawea Pass and noticed no faceting of the current snowpack. The snow near the pass and on the ridge is very wind affected as is to be expected and dropping into the bowl on the east side of the Pass the snowpack there has a distinct sun crust. Dug around a little bit at 8600 ft on a NE aspect and found a sun crust of about two inches with what felt like rounded grains below that. Even in the direct sun, the crust was taking a long time to rewarm and was pretty slippery..." Photo: H. Darby
