  • Cornices are a significant hazard this time of year. As temps warm above freezing, these overhanging masses of snow will become increasingly unstable. They can break farther back than you might expect and trigger large avalanches on the slopes below. They can fail naturally or with human triggers. 

  • This slide was triggered by the first skier of day off Saddle Peak. The skier was caught and carried 1,500 vertical feet. He was buried with his hand sticking out of snow. Unfortunately, he did not have a partner and was buried for over an hour. He did not survive. Photo: R. Gregoire   

  • This slide on Saddle Peak resulted in a fatality. It was triggered by a solo skier who was caught and buried. The slope was heavily wind loaded and the slide failed on a thin ice crust. Photo: R. Gregoire

  • Wet loose avalanches will be a growing concern as spring progresses. Sunshine, above freezing temps and rain can all produce dangerous wet snow avalanches. Watch for signs of instability such as roller balls, small point releases and wet snow above your boot top. Avoid being on or underneath steep slopes if signs on instability are observed.

  • The crown ranged from 1-3' deep and was 75-100' wide. The avalanche was new, windblown snow on top of a thin ice crust. Aspect is east, slope angle is 37 degrees, and elevation is 9019'. Photo: GNFAC

  • Looking down the path from the crown. The "X" marks the burial location. Photo: GNFAC

  • Looking uphill about half-way down the path. The crown can be seen at the skyline. Photo: GNFAC

  • The distance from the burial location to the crown line (seen at the top of path at the skyline) was 1500' vertical. The skier was buried with his hand sticking out of the snow. His head was about 1.5' from the surface.  Three rescuers got to him 75 minutes after he was caught. Photo: GNFAC

  • Large cornices loom over the slope where a skier triggered a fatal slide on Saturday (4/14) on Saddle Peak in the Bridger Range. Photo: P. Maleski

  • Both the crown and the victim's location are marked on the photo. The skier was carried 1500 vertical feet downslope and buried near the toe of the debris. Rescuers reached him 75 minutes after the slide occurred, but the avalanche was fatal. Photo: GNFAC

  • The avalanche was triggered by a solo skier, the first tracks of the day. The crown is marked, and the slide carried him down the path where he was fatally buried. Photo: GNFAC

  • A skier triggered the slide a few hundred feet from the top on a 37 degree rollover that was wind-loaded with the previous days 30" of new snow. The crown was 1-3 feet deep and 75-100 feet wide. Photo: GNFAC

  • The Bridger Bowl weather station is buried by the new snow. Photo: BBSP

  • Snow water equivalent of the snowpack at primary SNOTEL sites within the GNFAC advisroy area from October 1, 2017 through April 8, 2018.

  • This slide was remotely triggered on the Throne in the northern Bridgers. It failed on an ice crust 18-20" deep on a southeast facing slope. It broke 200 ft. wide and ran 5-600 vertical feet. With more snow and wind in the forecast, it will be best to keep terrain selections conservative in the Bridgers until the new snow has time to adjust.  

  • These cornices at the head of Sunlight Basin in Taylor Fork are bigger than big. The snow lip is a solid 30 feet away from the true ridge crest and could easily fool a rider or skier into getting too close to the edge. We are finding similar cornices in all our ranges. As the temperatures warm these overhangs will start to lose strength. Photo: GNFAC

  • A skier in Argentina Bowl south of Bridger Bowl Ski Resort triggered this wind slab on Wednesday. The likelihood of triggering wind loaded slopes has decreased, but it's still possible. Photo: anonymous

  • A skier found 2-6" thick wind slabs on the east face of Mt. Blackmore up Hyalite, and a cornice break (photo) that ran over 600 vertical feet down the north face. Photo: S. Casper

  • Strong winds out of the west-southwest loaded slopes and caused natural avalanches in the northern Bridgers. Strong winds will continue to produce unstable conditions in the Bridger Range. Photo: GNFAC 

  • Wind-loading Monday afternoon continued into the evening and formed wind slabs at many elevations. This photo is on the Bridger ridge, south of the ski area. Photo: B. Johnsen

  • South of Cooke City, a recent slab avalanche up Republic Creek from Monday (3/26).  A wind loaded, north facing slope around 9,700'. Photo: B. Fredlund

  • Reactive snow on steep edge of tree well. Sluffing or cracking on small rolls and micro-terrain features is a sign that loose slides or soft slabs are possible and may run far on larger, steep terrain. Photo: H. Coppolillo

  • Big Sky ski patrol triggered this slide with explosives on Sunday (3/25). It is in a heavily wind loaded pocket. Heavy snow and strong wind formed fresh slabs on Saturday. Many have gained strength, but are possible to trigger for a day or two. Photo: BSSP

  • Wind loading after Saturday's snowfall (3/24) created avalanches on Saddle Peak that ran over the cliffs. Photo: GNFAC

  • There is 7' of snow on the ground in Bacon Rind (HS 240 cm) and it is stable today. The main concern is the new snow above the ice crust that formed 10 days ago (seen as the stripe behind the shovel) and in two snowpits our stability tests did not propagate. Melting, rain and/or more snow with wind would change the stability, but for now it's good. Photo: GNFAC

  • The snowmobiler walked to the edge of the ridge when the cornice broke carrying him over a cliff. Photo: Fremont Co. SAR

  • Yesterday, (20 March) a snowmobiler was injured when a cornice broke and carried him down a slope and over a small cliff in the Centennial Range of Idaho between Sawtelle Peak and Mt. Jefferson. Fremont County Search and Rescue reported the rider was injured and ambulatory, and evacuated by air ambulance to a hospital.

  • Slab avalanche that broke in the 8-10" of storm snow that fell Thursday (3/15). It is out of bounds just north of Bridger Bowl and was likely triggered sympathetically during avalanche control on Friday. Photo: GNFAC

  • These avalanches appear to be natural and broke in the 8-10" of snow that fell Thursday (3/15). Photo: GNFAC

  • Dry loose avalanches and small storm slabs were observed in Beehive Basin. With more snow in the forecast, similar avalanches will be likely. Photo: GNFAC

  • Cornices will be a problem for the remainder of the season. It's best to give these overhanging chunks of snow a wide berth along the ridgelines and limit time on slopes below. Photo: B. Zavora
