A recently observed avalanche that ran something in the January 5th cycle (within a few days of 1/5). This occurred on a westerly aspect around 10,000. Photo: B Fredlund

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." Photo: BBSP

*Note: BBSP does not perform any avalanche mitigation outside of the ski area boundaries

We looked at the avalanche in Hyalite that was triggered on Saturday 1/9/21. The slope angle was 33-35 degrees on the starting zone of the lookers right path. It broke 2-3’ deep on weak facets below a hard slab, 1000’ wide and the debris was 5-9’ deep. East aspect, 9,800’ elevation. Photo: GNFAC

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 2-4' deep. Photo: GNFAC

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

The thin snowpack at the Throne is harboring the largest depth hoar I have seen this season. 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

From obs: "1/9/21 350pm: 333 deg NNW, broke on ski cut lookers right approx 60 ft across, 200 ft or so total distance to toe of debris. Broke 2.5/3 ft deep on a wind loaded pocket, slid on a firm surface with facets on top."

From email: "...I found a small piece of this mostly low angle slope to have avalanched, probably from a day or two ago, a handful of older tracks were near it. I measure most of this slope around 26-28 degrees... This is on the farthest south part of the top meadow. An epic amount of whumphs up there, I stopped counting after I got to 10 on my second switch back. Our best one knocked snow out of a tree 100’ away. It feels like remote triggering is a very real possibility. Skies were more overcast than expected. While it never went blue, the sun poked out a little in the afternoon. Cold temps, 0F in the AM, warmed to 24F in the PM. 5-6mm surface hoar everywhere,..." Photo: S. Jonas
