Primary Problem: Wind-Drifted Snow
Bottom Line: It is snowing and blowing and human triggered avalanches are likely. In places with more new snow, avalanches in that new snow will be easily triggered. Avalanches breaking in drifts are the likeliest problem you’ll encounter today and would be large enough to bury you. The weak layers that have been consistently avalanching for the last two months are also being loaded again. Keep your slope angles less than 30 degrees while we wait and see how they handle this loading event.

From obs: "I was skiing inbound at Bridger Bowl today and noticed a small wind slab avalanche that failed on quarter saddle. I estimate comparing the photo to Google Earth that the slide ran 250 vertical feet and broke 100+ feet wide. Ongoing wind-loading and obvious instability. "

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

Clear weather and temperature fluctuations can make a weak layer in the top few cm of the snowpack called near-surface faceting. There are 3 dominant types which are explained in Bruce Jamieson’s new video featuring Karl Birkeland, Doug Chabot, Ed Adams, Mike Cooperstein, Ethan Greene and Mark Staples.
