Bottom Line: Recent snow created small and isolated avalanche hazards which can be harmful, especially in high consequence terrain like above cliffs, rocks, trees or on firm, steep slopes. Wind slabs that formed yesterday will be more difficult to trigger today, but a few fresh drifts will grow with increasing west winds. As temperatures warm through the day, or if there is rain this afternoon, shallow wet loose slides could be triggered. The snowpack is generally stable, and avalanches are unlikely aside from small and isolated hazards. Watch for signs of recently drifted snow or the snow surface getting wet before you ride or travel below steep slopes.
Primary Problem: Wind-Drifted Snow

  • From obs 4/9/21: "...we saw widespread natural wind slabs on N-NE eastern slopes in the Northern Absarokas (photo). Winds increased throughout the morning, and evidence of wind transport became more apparent at higher elevations. We found that on aspects unaffected by wind loading, the new snow layer was not cohesive and only saw minor sluffing." Photo: E. Schreier

    A small avalanche hitting the North Bowl Road.

    Bridger Bowl is closed for the season and the ski patrol is on summer vacation. This means no one is mitigating avalanche hazards or closing terrain as conditions change, so skiers and riders have to make avalanche-related decisions for themselves and be prepared for partner rescue. It also means that familiar routes such as North Bowl Road may become unsafe. Photo: GNFAC

  • This was a natural wind-slab avalanche releasing below the upper cliffs on Saddle Peak on March 28th. Photo: Anonymous

  • Extreme winds on 3/28/21 transported snow that fell over the past week into fresh wind slabs. Photo: BSSP

  • From obs: "Deep slab avalanche in Blackmore Basin that appeared to break on the depth hoar near the bottom of the snowpack. It was on a wind loaded NE facing slope at approx. 9,500 and looked to break on a slope in the 35-40 degree range. The crown was about 8'-10' deep and 200' wide. It broke to the ground and ripped out several small trees." Photo: JR Mooney

  • Ian and Dave stop to do a quick stability test as they hunt for a layer of weak snow 1-2 feet under the surface. Photo: GNFAC

  • From obs: "On our way up the summer trail route to Hyalite Peak our party of three remotely triggered a small avalanche from the skin track at around 9,600ft on a east facing aspect. The storm slab went about 4 inches deep and 150-200ft across a small roll over feature. We were about 150ft away when we triggered the slide." Photo: C. Kussmaul

  • Deep slab avalanche on Arden Peak at the back of Maid of the Mist basin in Hyalite. Probably broke between Feb 22 and Feb 28, 2021 Photo: GNFAC

  • From obs 3/6/21: "Two large natural avalanches in Maid of the Mist Basin. One of them ran on the east face of Arden Peak (Peak 10,201) which propagated across the entire face. Could have been triggered by a cornice fall then stepped down to deeper layers. The second was on the NE face of the peak Fat Maid and Skinny Maid come from. Also propagated across the entire slope. Crown height between 6'-8' in most places." Timing of these slides is unknown. Probably in the last week, but maybe older. Photo: S. Enloe

  • We saw these recent wet loose avalanches on 3/6/21. SW aspect, 9,100'. They likely ran during above freezing temperatures between 3/3 and 3/5. Photo: GNFAC

  • From obs: "Small D1 avalanche on south-eastern aspect around 7800ft. Looks like solar released on older layer a day or two ago."

  • From obs: "While touring above the canyon this morning, I noticed a very recent wet slide (would guess this incident occurred yesterday afternoon, March 4th). This was a skier triggered slide on a E aspect at an elevation of 7200. This slide was roughly 50 feet wide and ran about 50 feet, I estimated this crown to be 2-3 feet deep, slid all the way to the ground. This occurred below a steep roller."

  • Sled Skiing in Third Yellow mule... after an air onto the slope the impact from landing resulted in a fracture and failure to / near the ground... in addition, a remote trigger occurred on adjacent slope... 200-300 ft to the skiers right. No body was caught in either slide. Skier that initiated failure was moving at high speed and was beyond slide path before majority of snow movement began. Photo: W. Miller

  • This avalanche was triggered on Sunday, 2/28, when a skier released another slide 2-300 feet away. It broke at the same time. No one was caught. This was in the Third Yellow Mule on Buck Ridge.  Photo: W. Miller

  • There was 6' of snow off the ridge in the Bridger Range on an east facing slope. The top 2 feet were recent wind drifting that broke clean in our stability test which indicated unstable conditions (ECTP18). We expect similar conditions and instability with wind-loaded slops throughout our forecast area. Photo: GNFAC

  • In the last 24 hours (2/28) 12" of low density powder and 40-50 mph west wind made it easy to trigger wind-drifted snow. Alex kicked these drifts which cracked and moved. We expect similar conditions and instability with wind-loaded slops throughout our forecast area. Photo: GNFAC

  • The Friends of the Avalanche Center, in partnership with the City of Bozeman, put in a Beacon Park at Beall Park. It is located on the north side of the Beall building between N. Bozeman Ave. and the ice rink. Stop by with your avalanche transceiver and do a few practice rescue drills. Your partner will thank you. Photo: S. Regan

  • Ski patrol reported this large natural slide on 2/7/21. Photo taken 2/10/21: BBSP

  • From email: "Skied the ramp outside of Bridger Bowl today, saw these small NE facing crowns at 8350'. We also experienced localized cracking while skinning at the density change interface of the new and "old" snow (8-12" at this elevation by 4pm). No other observed avalanches, no other cracking and no collapsing. New snow was sluffing easily on steep terrain." Photo: D. Sandberg

  • On 2/7/21 skiers in Beehive reported: "Numerous large collapses, ECTP in several pits on mid-pack facets, and triggered a test slope remotely from flat terrain. It broke in the old snow, but towards to top, maybe 10cm below the interface with the last week’s snow. Propagated over 50m, crown depth 60-100 cm. Would be solid size 2 if the slope wasn’t 20m tall." Photo: Sam H.

  • This 4' deep snowpit shows the new snow over the last 4 days: everything above the blue card, over 2' of snow measuring 2" of SWE. Avalanches are breaking on the very weak, sugary snow (facets and depth hoar) 1-1.5 feet above the ground. The smooth surface in the bottom left of the photo is the failure plane. Photo: GNFAC

The Last Word

We will end regular forecasts this Sunday and will begin issuing weather, snowpack and avalanche updates every Monday and Friday as well as updates to social media through April. Avalanches will still be possible if there is snow on the ground. Remain vigilant with safe travel practices and snowpack assessments for the duration of your riding season.
