Bottom Line: Avalanche conditions remain dangerous today. Wind is blowing snow and loading slopes. Weak layers in the top 3 feet of the snowpack, as well as sugary, weak snow at the ground, are still adjusting to the weight of the weekend snow and recent wind-drifting. Avoid avalanche terrain and runout zones (slopes underneath).
Primary Problem: Persistent Weak Layer

From obs 1/29/23: "Noticed multiple crowns while driving up to bridger bowl this morning. Most evident was wide crown line on saddle peak below the corniced ridge stretching from the summit towards football field. Another was an obvious crown on what I believe is Argentina Bowl south of Saddle peak. From a distance, this all looked like new snow crowns and didn’t seem like anything stepped down to our buried weak layers. East wind had an interesting effect on the ridgeline above bridger bowl."

BBSP noted on 1/29/23: "A crown on Saddle Peak could be seen in today's bright light.  It began at the football field, extended to the top of the peak and a flank was visible extending down the skyline.  A secondary pocket pulled on the north facing slope below the Going Home Chute.  On the west side St Lawrence pulled out wall to wall, and behind Mountain Mother had a crown that was more filled in on the south facing side that began about half way down.  Also, a crown was noted on the south facing ridge of Bradley's Meadows ridge below the cliffs."

  • From obs 1/28/23: "There were numerous debris piles, point releases, and crowns on the north face of Elephant and the northeast face of Blackmore this morning.  Most of them appeared to have run during the storm (1/27) and had been covered by at least 6 inches of new snow." Photo. S. Regnerus

  • From IG:

    Fairy lake today (1/27/23), remote trigger from top of the ridge

    About 2-2.5ft deep about 75-100 ft wide

     

  • From Big Sky Ski Patrol 1/21/23: "skier triggered a surface wind slab in Wyoming Bowl that broke 8-12” deep. It propagated to an estimated 150’ wide- SS, R1/D1.5... The slide was small, no one was hurt, and the avalanche was reported (which we appreciate), with no further public involvement other than the trigger."

  • Another slide was seen from the highway in Argentina Bowl. This slide appears to be a shallow soft slab that ~50 ft wide and ran ~500 vertical ft.

  • Darren Johnson was a passionate skier, patroller, and wildland firefighter and this fund helps his memory live on. During the week of January 16, 2023, there are two events happening to help spread awareness about the DJ Fund and generate donations for the next recipients to attend National Avalanche School in October 2024. The first event is at the Independent Theatre on Tuesday, January 17. This charity event has a $10 entry fee which includes a raffle ticket to a silent auction. On Thursday, January 19, join us at Beehive Basin Brewery for a raffle and pint night in which $1 from every pint sold goes into the DJ Memorial Fund.

    To donate to the Darren Johnson Avalanche Education Memorial Fund visit djmemorialfund.org, or join us at these two exciting events hosted by Yellowstone Club Ski Patrol. Huge thanks to all who have sponsored and donated to these events.

  • At 1:30 PM on Jan 6th a large avalanche poured over the cliffs on Saddle Peak, outside the boundaries of Bridger Bowl. Clouds obscured the starting zone. Multiple groups were in the runout zone, including a party building a jump. One person was caught and buried up to his neck. He was able extricate himself and was unharmed. He estimated the debris was at least six feet deep.

    We believe this was a natural avalanche that broke in the new and wind drifted snow. Bridger Bowl measured 6" of new snow with 0.75 inches of Snow Water Equivalent at the Alpine Wx. Station.

  • Jan 3, 2023: Dug a pit and found weak and unstable snow. We backtracked to the ridge. A recent avalanche from 2 days ago involved new, windblown snow.

  • We looked at the avalanche that killed a snowmobiler yesterday (12/31/22) on Crown Butte near Cooke City. Our deepest condolences go out to the family and friends of the victim, and those involved with the rescue and recovery. Photo: GNFAC

  • On December 31, 2022 a snowmobiler was killed in a very large avalanche north of Cooke City, MT. The avalanche occurred near Daisy Pass on Crown Butte on a southeast facing slope at 9,800’. The avalanche appeared to be 2-4' deep, 500' wide, 600' vertical, and broke on weak snow near the bottom of the snowpack. Photo: GNFAC

  • On 12/28/2022 from the lower south boundary of Bridger Bowl, ski patrol saw an old avalanche crown and debris on steep rolling terrain below the large cliffs on Saddle Peak. Appeared to be 1-2 days old, 2 feet deep and 60 feet wide, N-R2-D2-O

  • Many slick roofs shed this winter's snow with the above-freezing temperatures. There are some impressive fracture lines at the ice rink in Bogert Park in Bozeman. Photo: GNFAC

  • Today we toured up Beehive Basin to Prayer Flags and down into Bear Basin. We found moderate winds transporting snow at Prayer Flags. We also observed a recent small natural avalanche that broke just below the cornice at prayer flags (9200'). It was unclear if a cornice collapse triggered the avalanche. We did not go to the crown, but estimated it to be about 20-30 feet wide, 6-8 inches deep, and running less than 100 feet. Photo: J. Breen

  • From Obs: "Natural wind slab, likely triggered by cornice fall in the last day or two, on a NE aspect at 8500’. Propagated ~150’ wide and ran probably 300’. Slab thickness seemed to be 18-24” at the thickest. No sign of stepping down deeper into facets in the snowpack, although adjacent to this slide there was evidence of an older slide (previous to recent storm cycle) that failed deeper in the snowpack."

  • Skier triggered avalanche on Saddle Peak. 12/16/22.

    From obs: "I would estimate 2-4’ deep, 150’ wide. ... It ran full length into the bottom of Argentina bowl and south gut with a massive powder cloud. "
     

  • Went on a tour today with some buddies with hopes of skiing the great one. Once up in the sac bowl, we opted to back away given the wind was howling. We skied the white worm, and saw numerous cracks shooting across the slope. I opted to ski a short and sweet N facing couloir which started out pretty firm into avalanche bowl. About halfway down, I had a wind slab release after one soft turn with the deepest portion of the slide being one foot. I was not carried as I immediately cut out of the fall line, the slide rolled for about 200 vert. My friends opted to ski the direct headwall exit and had numerous small wind slabs pull out. Some areas were stripped to rock of snow. Photo: T.S.

  • I dug a pit above Silken Falls in the gulley. I found a weak layer of facets breaking about 10" under a wind slab (ECTP15). We did not get any cracking, but the terrain is very serious and even a small slide could be deadly. We did not feel comfortable center punching up the gully. Given how much traffic the gullies are getting, I do not think it is widespread, but it's out there and could avalanche.

    Wind and snow this weekend may make this layer more unstable, so it's important to be careful crossing exposed terrain. Either rope up or tun around if it is suspect.

  • Toured up to the NE shoulder on Mt. Blackmore yesterday. Winds were strong and variable, but mostly gusting from the S-SW. A lot of snow was moving around, skin tracks were filled in very quickly, and you could actively see small cornices starting to build on the lee side of the ridge. Photo: H. Darby

  • Saw a group of skiers trigger a small wind slab avalanche on an eastern aspect at around 8,300' in the main fork of Hyalite in "Candy Land" just south of the climb Big League Chew at 2:00pm on Saturday (11/26). Crown looked to be around 2" to 1' and 90' wide. The slide ran maybe 100'. No skiers were caught. Photo: Anon
