Primary Problem: Persistent Weak Layer
Bottom Line: You can trigger a large avalanche that breaks 1-3 feet deep on weak sugary snow, and freshly wind-loaded slopes should be avoided. On non-wind-loaded slopes the likelihood of a slide is lower, but consequences are similar. Before traveling in avalanche terrain carefully assess the snowpack and identify areas to avoid. Look for signs of instability and be ready to change plans if you see any red flags. Choose smaller, simple slopes with clean runouts and no wind-loading.

From obs 2/20/24: "On the drive up Bridger canyon this morning we noticed an avalanche on an east-northeast facing slope at the ridge near Bridger peak that was not previously noted or reported. Likely natural, possibly happened overnight or yesterday, but maybe earlier and went unnoticed? It looked 1-2’ deep with rocks showing through parts of the bed surface.... Debris did not appear to make it all the way down the chute to flatter runout. But, light was not great and all dimensions were difficult to confirm."

On 2/21 we drove up to look at the slide through binoculars. The slide broke full width of the starting zone and obviously ran to the bottom of the path, although the debris was not visible. Measured on gps, the slide is 300-450' wide 

Slide was noticed by a member of BBSP on Monday 2/19, and likely happened on 2/18 or late 2/17.

  • On 2/1/24 on a drive up the highway I could see many recent wet avalanches, both wet loose that gouged through the snowpack and wet slabs about one foot deep and 50-100' wide. Many size D2, some smaller. Happened sometime between Monday and today (1-3 days old, maybe some this morning). The main spots for recent wet avalanches were on Bridger Peak (this photo) and south of the Throne. Photo: GNFAC

  • From obs: "The location is the knoll under the Saddle Peak cliff that can be accessed by traversing through the southern boundary gate from Bridger Bowl. The slide propagated on a NE aspect going into a gully. The crown looked to be 1-2 feet tall with an approximate width of 30 feet. There are numerous tracks that go in and out of the slide path, but could not tell if it was triggered by a skier. A friend who I was with said that the slide had not been there the day before."

  • From GCSAR and Bridger Bowl Ski Patrol:

    A skier triggered a slide descending the skyline/nose of Saddle Peak. No one was caught. It initially triggered at the first rock band, then pulled out much wider at the second rock band. The skier was on his second lap was the third set of tracks on the peak. All tracks were accounted for and a beacon search of the debris came up empty.

    Depth was described as "full depth" (2-3') and running on the depth hoar.

    Crown was 80' wide on the first horizontal band and 500+' on the second. The lower crown wrappped around the ridge out of view.

  • On 1/20 At the top of The Ramp/Wolverine I pushed on some small wind-loaded terrain features with skis. About three inches of soft snow moved/cracked no wider than my ski width, then one step lower a hard slab cracked out about 10' wide, 10-12" deep and did not move more than a few inches downhill due to flatter terrain supporting it below.

  • Monday or Tuesday, a small natural avalanche released when strong winds stripped and loaded slopes at all elevations. Photo: GNFAC

  • The wind picked up in the Bridger Range and transported snow into unstable drifts. Photo: GNFAC

  • We triggered a small avalanche on a test slope at the ridgeline of the ramp. Wind was transporting the recent snow into drifts sensitive to human triggers. Photo: GNFAC

  • We dug 3 pits on or around the Ramp which is to the north of Bridger Bowl. One was SE facing, the other was E facing and our last was N facing. Depth ranged from 45 cm to 67 cm and all stability tests (6) had ECTN12-14. Photo: GNFAC

The Last Word

On Thursday Ian rode in the Independence Mine area (up the Main Boulder, outside our advisory area) to check out the snowpack conditions before the Sweet Grass County Recreation Association Poker Ride. Watch his video for a snowpack update. Avoiding riding on and staying out from under slopes steeper than 30 degrees would be a wise choice if you’re headed up to that area.
