Photos- Cooke City Area

  • 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

  • Riders triggered this slide on Monday (4/9) on the southwest facing chutes of Scotch Bonnet mtn. near Lulu Pass. Nobody was caught. Photo: Anonymous

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

  • 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

  • Recent snow was drifted by strong wind into 1-2' deep slabs that were reactive today (3/30). This snowmobile triggered slide is an indicator that fresh slabs are unstable and larger wind loaded slopes should be avoided.  Photo: GNFAC 

  • This 2' deep natural avalanche was observed on 3/30 and indicates fresh slabs are unstable and larger wind loaded slopes should be avoided for a few days.  Photo: GNFAC 

  • Recent snow was drifted by strong wind into slabs that were reactive today (3/30). This small test slope is a good indicator that fresh slabs are unstable and larger wind loaded slopes should be avoided.  Photo: GNFAC 

  • 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

  • A cornice fall triggered this avalanche on Lionhead Ridge that broke sometime late Saturday (3/24). Photo: B. Rasmussen

  • 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

  • Roof avalanches can be common this time of year when warm days promote the rapid shedding of the deep roof slabs. Photo: B. Fredlund

  • 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

  • Skiers observed these natural wind slabs near Goose Lake north of Cooke City on Friday (3/23). Photo: B. Zavora

  • Skiers outside of Cooke City observed a few natural avalanches today. These slides occurred in upper elevation, wind loaded terrain. Photo: R. Gilmore 

  • 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.

  • 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

  • Large cornices are the main avalanche concern around Cooke City. Give these bus sized chunks of snow a wide berth along the ridgelines and avoid spending time on slopes below. Photo: GNFAC 

  • Wet loose avalanches can be seen in lower elevation gullies on southwest facing slopes of Sphinx Mountain. Photo: B. VandenBos

  • Roller balls are a sign that the surface snow is getting moist. As these become more numerous and grow in size, they indicate that the surface snow is getting wet enough to create shallow, loose snow avalanches. Photo: H. Coppolillo
