Bottom Line: The snowpack from Lionhead through the Bridger Range is shallow with a distinct layer of weak, depth hoar near the ground and a stripe of feathery surface hoar buried under 6-18" of snow. It will take weeks or months to trust these layers fully, but they are adjusting to the current load and avalanches are less likely. Stability is currently similar in these ranges but today's snowfall will heavily favor the mountains around West Yellowstone. As the snow begins to add up, stability will decrease.
Primary Problem: Persistent Weak Layer

Routine avalanche mitigation within the boundaries of Bridger Bowl sympathetically caused half of the Football Field on Saddle Peak to avalanche immediately south of the boundary. "Debris ran over the cliffs pulling out spindrift cones that were up to 5 ft deep." 

*Note: Ski Patrols do not perform any avalanche mitigation outside ski area boundaries.

  • The recent wind has stripped the snowpack bare in spots and created large drifts in others at the Throne. Photo: GNFAC

  • From obs: "On our way out to fairy lake we stopped in the open meadow just before the campground and noticed a sizeable natural avalanche on a northfacing slope that appeared to have broken on the layer of sugary facets on the ground. From our perspective it appeared to have happened a few days ago likely after the loading event midweek." Photo: E. Marcoux

  • Skiers triggered this avalanche on Flanders Mountain on 1/9/21. It was triggered out of the photo to the right on a seperate slope around the corner. It propagated over 1000' wide, and looks to be 6' deep at deepest. Photo: A. Blackmer

  • From obs: "the whumpf I had heard previously remotely triggered a series of 7-8 large cracks that ranged from 30-100 feet wide. ... As I carefully descended the meadow, I saw many more cracks throughout the slope from the same remote trigger event. Additionally, I triggered two more significant whumpfs with shooting cracks 10-40 feet wide. We determined our remote trigger was at least 300 feet away from where the snow collapsed and cracked"

  • Natural avalanches on Bridger Peak observed at 1200 on 12/24/20. These occurred within the last 24 hours after the area had 8-12" of snow (.3-.5" SWE) and strong winds. Weak sugary snow on the ground failed under the weight of fresh slabs. This activity is a sign that the snowpack has a poor structure that will struggle to support future storms. Photo: GNFAC

  • Strong wind over the weekend deposited fresh drifts, about 10" deep, over weak snow. Bridger Bowl ski patrol triggered a few of these drifts on Monday (12/21) during avalanche mitigation. Photo: BBSP

  • A skier kicked off a larger than expected cornice as they skinned up the ridge on the W side of Beehive basin on Sunday (12/20/20).

  • From obs.: "Kicked off a larger than expected cornice as we skinned up the ridge on the W side of Beehive basin. Wind was blowing 20-ish across the opening, cornice had grown pretty good-sized for so little snow. I was making a turn on skins to get back away from the edge when the cornice gave way, probably pulled 25 feet end to end and broke a good 5 feet back from the lee edge of the cornice. I was able to get off the cornice and avoid going over the edge. No activity on the slope below after cornice drop,... although there was a decent hard slab that pulled out just below the ridge when the cornice dropped onto it.... Hard slab on the edges was about 10" deep, some big chunks of cornice on the slope for any future riders..."

  • Light wind created soft drifts of new, low density snow near the ridgeline in the Bridger Range. This wind slab easily cracked when touched with skis, 20 feet along the ridge and 5-10 feet down, but didn't slide. This is a sign drifts will be unstable as they grow with more snow and wind.

  • This avalanche in Sluice Box at Bridger Bowl released mid morning on 12/3/2020. Crown estimated at 2 Feet. Photo: BBSP

  • A skier saw this avalanche get triggered at Bridger Bowl (Schlasmans Lift) this afternoon 12/2/2020. "...The toe of the slide was all of 6’ deep. There is about a foot of fresh sitting on top of faceted crust that is sitting on top of more facets and another crust,..." Photo: Anonymous

  • This snowpit at Bridger Bowl was on a shaded ENE aspect at 7,800'. The lower two thirds are mostly sugary, weak facets with a hard crust in the middle. This weak snow is not the best foundation for the winter's snowpack. Photo: GNFAC

  • Under the Schlasman's chairlift at Bridger on November 29, 2020. Snow depth ranged from 3" to 18". Conditions were generally very shallow and rocky. Photo: GNFAC

  • From obs: "NW of Elf Lake. Lower Pitch in Trees, 2 well defined weak layers present primarily at surface (30cm) and just below at (20cm). 7785FT, Clear, 25F. 10 degree Slope Facing Easterly in forest below steeps." Photo: J Budreski

  • From obs: "while I was skinning up to the rollover I popped off a wind slab approximately 50 X 50’ with a 6” crown. The slab itself was only about 4” thick and only slid about 5” down the slope before stopping, and I was able to stop and then turn around and ski off of the slab without it moving any further. The 4” of dry slab was sitting on about 3” of sugary snow that was on a very firm icy bed surface." Photo: Anonymous

  • From IG message: Northern Bridgers is seeing a lot of avalanche hazard. Deep wind slabs where I was on Hardscrabble (SE aspect and NE). On my skin out I saw two avalanche crowns on the NE side of Pomp Pk. One had a party of two that triggered it and they were starting to descend away from avy terrain. Asked some other skiers up there what they saw and similar findings throughout the area. Dug one pit that showed facets on the ground covered by hard, icy snow with wind loaded snow on top of that. On my descent of Hardscrabble i picked my way thru the exposed rock and when I got into deeper snow it propagated about 60% of the time but did not slide really. Photo: D. Britt

  • The BBWC (Bridger Bowl Wind Cloud). Strong winds drifted recent snow into slabs that could avalanche on steep slopes. Early season snow means we need to be thinking about and managing avalanche hazard when we travel in the mountains. Photo: B. Rode
