Bottom Line: Avalanches will be mostly confined to new snow that falls. Shallow wet slides are possible if rain or warm temperatures melt the snow surface. Anticipate new snow stability to decrease with wind, sun or above freezing temperatures. Be aware of deeper wet slides if the snowpack doesn’t freeze overnight, or if there is heavy rain. Now is just as important as ever to be diligent with snowpack assessment and choose terrain carefully. See our forecast page for general spring snowpack and travel advice.

Debris ran very far into the runout compared to similar sized dry slabs that often occur on this path. "South side of 1/4 Saddle slid sometime last night.

  • "South side of the Glide Plane released as a glide avalanche last evening (May 12th) sometime around 6 pm according to source. Bed surface was ground in starting zone of wet clay soil sparsely covered in long grass.  Debris chunks, some snowmobile sized, rode up on surface and slid approx. 200 vert.  Debris could have bumped a tower on the old Alpine lift if it still lived there. Last freeze was 6 am on the 10th of May.  The high temperature on the 12th was 59 degrees at 4 pm."

  • This slab avalanche near Goose Lake outside of Cooke City appears to be a wet slab triggered by a wet loose slide. Warm temps and sunshine the past few days were the perfect recipe for wet snow avalanches. Photo: B. Fredlund 

  • Large natural avalanches were observed near Goose Lake outside of Cooke City. These slides are a reminder that unstable conditions still exist in upper elevation terrain. Photo: B. Fredlund 

  • Wet slabs were observed near Cooke City on 4/20/19. Riders reported multiple slides similar to this one. Photo: K. Taylor 

  • Observed 4/20/19. Crown estimated 3-5' deep. Above freezing temperatures, sunshine and rain created a wet and weak snowpack. Photo: G. Antonioli

  • Below 3-5" of new snow there is a supportable frozen crust on top of a wet snowpack on most slopes. Avalanches are mostly confined to the new snow on top of this crust (wet loose, dry loose, wind slabs). However, where the snowpack did not freeze below the new snow, or when this crust melts, deeper wet slides are possible. Photo: GNFAC

  • Snowmobile-triggered slide near Fairy Lake on Saturday (3/30). New snow was drifted into small wind slabs that may remain reactive in isolated areas.  Photo: P. Cronin

  • Near Cooke City we found a generally stable snowpack, similar to the rest of the advisory area. For the next few days avalanches will be confined to new snow that falls. These slides can be dry or wet loose slides, or fresh wind slabs. Carefully assess the stability of the new snow before riding steep terrain. Photo: GNFAC

  • Outside Cooke City up Zimmer Creek, a skier spotted this cornice fall which triggered a small pocket down low. Photo: F. Madsen

  • Many wet loose and wet slab avalanches were seen near Zimmer Creek (north of Cooke City) on south and east aspects. Temperatures were warm at 10,000 feet. Photo: F. Madsen

  • This photo near Lionhead, is indicative of the wet loose avalanches we are seeing on many low elevation, south facing slopes throughout our advisory area. Daytime temperatures near 50F will make avalanches like this more frequent and widespread in the coming days.

  • A small wet loose and slab avalanche on a SW facing slope near Daisy Pass. These slides were observed on March 17th, 2019. The wet loose looked at least a day or two old, the small slab a bit older. The slab broke ~18" deep at the ground, near some rocks. This slope had an unusually shallow snowpack.

  • Low angle metal roofs have heavy, thick slabs of snow that built up during persistent cold temperatures. These slabs will slide during warm temperatures. Be on the lookout for overhead hazard and be cautious where you walk or park your car during warm sunny days. An additional urban hazard are large icicles are that will break during warm days. Photo: A. Schauer
