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

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

  • From obs 3/28/21: "Saw this slope which frequently slides had been triggered on our way out last night [lower left in photo]. Slid to the ground but I expect it was mostly new snow as there is a larger old crown visible further uphill... I did see two other small pocket slides yesterday also in new snow on bed surfaces of older slides... General snowpack is getting very deep now but a thick junk layer remains at the ground everywhere I dug sleds out." Photo: J. Gerardi

  • 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

  • Small snowmobile triggered slide in the new snow on Buck Ridge. Likely triggered on 3/26/2021. Photo taken 3/27.

  • From obs: "On Friday, my partner and I went into Middle Basin with the objective of skiing Middle Peak, and possibly the short couloir that splits the face. That morning we dug a pit on the east facing aspect of the beehive/middle basin ridge (ECTx). Encouraged by our results, we continued on to the base of middle peak and dug another pit (ECTp 30) on the south-facing ice crust. We continued on to summit middle peak and ski down the face to the entrance of the couloir, we descended 20ft into the entrance on soft loose snow and dug our third pit (ECTx), we replicated our results and decided the feature would be safe to ski. At ~1pm the first skier descended the slope, and triggered a small windslab (4-8in and 20ft wide) about 100ft down the slope and skied away uncaught. Skier 2, descended a lower angle slope to the east."

  • 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 email: "We both set off some small sluffing on the west side of the ridge between Middle and Beehive on our way out; the snow on that aspect was a lot thinner and more prone to sliding on the older icy crust under the new snow. Photos are from below where we skied out; we dropped onto the west-facing slopes maybe 100' south of the prayer flags." Photo: P Calabro

  • 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

  • Skier triggered sluffs on Fan Mtn. Small wet and dry loose avalanches were triggered depending on aspect/elevation. 3/18/21.

  • 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."

  • "Ran into this slide today. Tail end of Middle Basin. Seemed to have happened sometime in the last week (2/23-24). Most likely during the heavy windloading event. Seemed to run on very small facets we believe formed during the cold spell before the last big storm hit." Photo: S. Knowles

  • 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

  • Natural avalanche on Buck Ridge. Observed on 2/27/2021 and looks to have failed recently.

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.
