Trip Planning for Bridgers

On sunday 4/14 a large wet loose avalanche ran naturally in closed terrain at Bridger. The larger of the two in the photo, on the right, is from 4/14 at 1230pm. The other slide, on the left, happened yesterday (4/13) or late in the day Friday. Photo: BBSP

On 4/13/24 There were many loose wet avalanches that ran over the last 1-3 days. They appeared to involved the upper 6-12" of the snowpack. Photo: GNFAC

Driving home from Bridger Bowl, I spotted a number of wet, loose avalanches in Argentina Bowl. It was 1:30 PM when I saw them, and the sun was still blazing. I would expect there was more activity as the afternoon progressed. Photo: GNFAC

From IG message: “Rode the banana today.. lots of fast moving sluff. Had a mid elevation pocket pop. New snow seemed to have bonded well, the spot that did pop had formed into 12” slab below rock face.”

Skiers triggered this avalanche on a north-facing slope near the Anger Lake basin.  The crown was 4-18 inches deep and propagated the entire width of the gully ~40 feet and ran the entire length of the gully ~500 vertical feet. The skier was able to ski out of the avalanche right as it broke and was not carried. Photo: Anonymous

The largest skier-triggered avalanche that we saw today. The crown extended out of frame below steep rocks. This avalanche broke ~1' deep within the recent storm snow. R2/D2. Photo: GNFAC

Riders saw this recent storm slab avalanche while riding near Fairy Lake. This avalanche was triggered by riders not in their group. Photo: Anonymous

Skiers in the Love Chutes triggered this avalanche after a ski cut produced no results. Further down the chute, the first skier triggered an 18" wind slab avalanche. They were carried 200' before self-arresting and were uninjured. Photo: Anonymous

A skier triggered a small avalanche on a steep north-facing pitch at the Throne, but it did not run far. Photo: GNFAC

While ski touring in Frazier Basin we saw at least 12 recent loose wet avalanches on east and south aspects. Most of them started near exposed rocks and entrained the upper 6" of wet snow. Photo: GNFAC

From IG: Very touchy on Hollywood wall this morning. All slopes easily propagated 4-6” deep on a firm bed surface. Most were less than 50’ wide with the exception of the slide in the couloir which propagated down the entire couloir, maybe 500’ wide, and ran through the exits into the main bowl.

There was a small wind-slab release out of Gibbs (I think), I suspect skier triggered, but I could make out a track. Photo: GNFAC

On our drive home we saw, what I assume were, natural wind-slab avalanches on Quarter Saddle (looked like a cornice collapse) and in Argentina Bowl. Bridger Peak was obscured by heavy wind-loading. Photo: GNFAC

The wind was transporting significant amounts of the recent snow at high elevations. This is Naya Nuki loading as seen from the Ramp. Photo: GNFAC

Skiers in Frazier Basin triggered several small wind slabs and saw widespread cracking on NW-facing terrain. Photo: C. Bayles

From obs: "Saw small avalanches on almost every wind loaded slope out of fairy lake. The one we spotted in the pomp twins had a defined crown roughly 100ft across." J. Alford

Skiers on 03/24/2024 observed this avalanche at the Playground that happened on 03/20/24. Photo: A. Newman

From obs. 3/23/24: "...Natural wet slab avalanche in the Playground, just North of Texas Meadows. It seemed to have been triggered from a wet loose avalanche that released from the cliffband above...." Photo: D. Sandberg

From obs 3/23/24: "...Also observed wet loose activity in S facing run off Texas (first run to the W of the summit)-photo attached. ..." Photo: D. Sandberg

From obs.: "Walked out the north gate of Bridger to the playground. Just north of Texas meadows observed a slide that ran sometime earlier in the week on a E aspect. Seems to have been triggered naturally by a loose wet coming out of the steep rocky terrain above. Ran about 200 feet was about 50-60 feet wide and crown was roughly 2-3 feet deep. Snow around the slide and on similar aspects was wet in the top 40 cms or so." Photo: C. Bayles
