Bottom Line: Gusty westerly winds drifted this week’s new snow into cohesive slabs which are ready to avalanche. Unfortunately, these drifted areas also have the best coverage for skiing or riding. Don’t get lulled into poor decisions while trying to avoid rocks. Carefully consider and evaluate both the snowpack and the consequences of triggering an avalanche before riding steep slopes.

This powder cloud from a large avalanche was seen on Black Mountain, up Pine Creek outside Livingston. Located outside our advisory area it is a sign of unstable snow, likely from wind-loading, that can be found throughout southwest Montana.

From obs. 11/10:  "Fitness skinning around Bridger Bowl yesterday and noticed a fairly large, new avalanche on the east face of the North peak of Saddle. Maybe 100 feet below the ridge, about 100 wide at the crown, ran thru the rock bands but not over the cliff. Was taken back by the clean propagation." -Albert

From e-mail 11/7/21: "Today, my partner and I set out to ski The Great One, with a plan to come up and over Sac Peak and then walk the ridge to Naya Nikki before skiing the Great One into Airplane Bowl. We found more snow than expected at the TH, about 6inches. On our way up to the pass just north of Sac we noticed the characteristic wind stripping down to scree on the trail to the pass. On one of the switch backs we were able to get about an 1-2” deep wind slab to propagate but not move down slope. Given the depth, we didn’t put too much stock into this. We proceeded to walk the almost snow free trail over to Naya Nuki before booting down to the top of the Great One. The skiers left side of the Couloir had some obvious wind load and after a few ski cuts felt comfortable continuing to ski. After my partner skied the majority of the top section, I followed and was entrained and taken for a slide in my own ‘slough’. I was carried about 40’ before I stopped, while the slough kept running for another 100-150’ arresting on the shallower angled slope before the break in the Couloir wall that feeds into Airplane Bowl. The entrained width of moving snow was about 3-5’ wide. There were no injuries, and we continued down to the base of the Couloir, deciding it would be more dangerous to try and go back up to get out. 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. Early season hubris, and is not even thinking about overnight wind totals has us more or less absent minded when we set out this morning. A mistake that could’ve been a lot worse if the slough had taken a larger wind pocket with it, and carried me over the same aspect that led to the fatality in the Great One last fall. No pictures of the slough, attached is a grainy cell phone pic of the slides in Airplane Bowl."

  • Skiers found a shallow snowpack and very windy conditions today. Snow was moving and loading slopes. Photo: H. Darby

  • From an obsevation: Skied up towards Arrowhead Bowl from Fairy Lake road. Snowpack is still very thin in the trees as you ascend towards the ridge. Strong westerly winds and exposed rocks deterred us from skiing the bowl itself. Down low we found variable conditions ranging from a few cm of graupel to a few cm of windboard and ice in places. We dug a pit at 8140 feet, 143º SE. The snowpack is 55 cm deep with a very distinct knife hard crust layer from 0-20cm above the ground, we were thinking that could be due to a rain on snow event that fell on top of the October snow. There is also a distinct knife crust 40 cm above the ground with new snow/wind blown snow on top of that. Weather today was mostly clear with a few scattered clouds and consistent winds, with very strong gusts from the west. Photo: H. Darby

  • A natural avalanche on Saddle Peak on 11/10/21. Strong winds drifted recent snow into thick slabs near the ridge. This slide was probably one of those wind slabs breaking and/or being triggered by a cornice fall. Photo: P. Hinz

  • 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
