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.

Avalanche Activity- Northern Madison

Northern Gallatin
Mt Blackmore
Skier triggered slide on Blackmore
Incident details include images
Mt Blackmore
SS-ASc-R2-D2-I
Elevation: 10,000
Aspect: N
Coordinates: 45.4451, -111.0040
Caught: 0 ; Buried: 0

 From e-mail: "A ski cut at the top of the slope produced a soft slab avalanche (R2 D2 SS). The crown was 10" deep and 60' wide. Several other skiers had skied a line to the skiers right of our route with no obvious signs of instability or avalanches. No natural avalanches were observed with the exception of some small wet point release slides on the E face of Mt Blackmore."

  • Debris from a wet slab that released naturally Tuesday evening on saddle Peak. 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. Looks like cornice drop then step down to near ground. Hi yesterday at Alpine was 62." -R. Elliott/BBSP

  • "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."

  • Recent spring snow has created instabilities that are confined to within the new snow. Areas such as ridgelines where fresh drifts form should be approached with caution. Cornices and fresh wind slabs should be avoided after fresh snow and/or strong wind. Photo. M. Gaffney

  • From e-mail on 4/11/19: "We found reactive storm slabs and touchy windslabs near ridgelines. We kicked off a small windslab in 4th of July from the top of the couloir. Attached is a photo of the crown to give you a depth perspective. It was about 6 feet across and 3-4 inches deep."

  • Snowpit dug at Bridger Bowl on Monday (4/8). Heavy snow and rain are creating dangerous avalanche conditions. Photo: BBSP

  • 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

  • From instagram: "Easily triggered 3" soft slabs/loose snow slides. NW facing Northern Madison around 11,000' Ran 400' on sun crust. At least 3 intentionally triggered." Photo credit: B. Gill

  • This wet slab failed within the past week on a west aspect in Beehive Basin. 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

  • Wet slab avalanches will be a growing concern as free moving water travels through the snowpack. This problem is most likely on mid to low elevation slopes that have a shallow snowpack and poor structure. Be aware of wet slabs as temperatures warm and the snowpack becomes increasingly unstable.
