Primary Problem: Wet Snow
Bottom Line: By mid-morning, on sunny slopes, any surface crusts that formed overnight will be breaking down and wet avalanche danger will be rising. Mostly we’re expecting relatively small wet loose slides, but the whole array of wet snow avalanche concerns are possible today, including wet loose slides entraining the whole season’s snowpack, wet slabs, or cornice collapses. Plan to get off sunny slopes early. Triggering avalanches in dry snow is becoming less likely, but is still possible, particularly on wind-loaded, high elevation, shady slopes.

On a steep roll, the second skier in our group triggered a small wind slab avalanche. This avalanche was 15-20' wide, 8" deep, and ran for about 30-40 vertical feet. The skier easily skied away from the slide and was not caught.

  • We triggered this small avalanche on a steep windloaded rollover on an otherwise mellow slope. This avalanche was 15-20' wide, 8" deep, and ran for about 30-40 vertical feet. The skier easily skied away from the slide and was not caught. Photo: GNFAC

  • On my drive to Cooke City I saw old slab avalanches in YNP near Mammoth and on Abiathar and Ampitheater among other places. These appeared to have happened earlier in the week. I also saw a more fresh looking persistent slab avalanche on Barronette, 2-3' deep and as wide as its terrain feature, 100-200' Photo: GNFAC
