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

  • Fro obs: "... an avalanche we saw out by Goose Lake yesterday (3/27)... we are pretty sure this wasn't there at 8am. On the way back (5pm) we noticed this large avalanche on the NE face of Iceberg Peak at about 11,200. It broke naturally in the new snow which was drifted heavily by SW winds (20-40mph all day). It appears to be 3-4' deep at the deepest spots, 600' wide, and ran 750'. There is a small area below the upper crown that stepped down, but tough to tell if that was just snow from the start of this storm. We did not notice any other activity in the area..." Photo: M.

  • 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

  • From email on 3/12/21: "...silver creek up to the saddle of Meridian in the NP yesterday. ... It was on the S aspect at 9,500ft of the shoulder that takes you up to the steep trees W of Meridian. It must have occurred in the last 24-48hrs due to not much snow had fallen since the avalanche occurred. It ran out down into the trees below. ... The crown looks to be over a foot deep, and the length must have been 50ft"

  • From obs 3/6/21: "Observed several smallish avalanches in Yellowstone National Park today. The interesting thing about this one is the bison track that goes into the slide. No telling if the avalanche was triggered by the bison, but the shallow snowpack is about 1/2 faceted, so maybe it was remotely triggered." Photo: J. Logan

  • From obs on 3/6/21: "Small slab avalanche with snowmobile highmark tracks. They do not appear to be related, since there are no tracks into or out of the slide. Approximate coordinates 45 4.313 x 109 55.380" Photo: R. Taylor

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.
