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.

Wet slab released naturally Tuesday (5/14/19) evening on Saddle Peak. "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." 

From BBSP Avalanche Atlas:

Interesting Events:

"The Glide Plane annually develops a significant glide crack starting on the north side of the lower section. There is only one event  (late 1960’s) of this path breaking out to the ground that can be recalled (glide avalanche). This occurred sometime when Randy Elliott was a grade-schooler and it did damage to a tower on the old Alpine lift. A deflector was then built onto the damaged tower. Mitigation efforts throughout the 80’s consisted of extensive boot packing early season and one attempt of encircling entire slope with det chord. These efforts proved futile, as the crack still developed and the slope remained intact.

Circa 2013 when the original Alpine chair was removed, the road cut known as the 3 Bears Traverse was filled back in with its original material that had been the foundation of the unload station of the old Alpine. This is the 3rd season (2016) with the original landscape, the glide crack has still opened but the slope has stayed in place.

Early 1980’s, Joel Jurgens wanted to test the slope because of rapid movement. Buried big shots on flanks and Goldilocks Traverse level strung together with det cord. –Randy Elliott 2017" - Pete Maleski 2015-2016

  • 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

  • A glide crack (the "frown" of dirt in the middle of the image) has opened up on the SE face of the Throne, in the Northern Bridger Range. Photo taken 4/1/2019.

  • Two pits on the west side of Saddle peak. They were dug relatively close to each other, but subtle changes in aspect and elevation resulted in very different conditions. North-facing slopes remain cold and dry for now, while anything that is in the sun is transitioning to a springtime snowpack. Photo: GNFAC

  • Two wet slabs that looked to have released during the past 48 hours. The smaller slide on the left had a debris pile that was 6' deep. The larger slide on the right failed at the ground and took most of the snow in the chute with it. The large slide may have been triggered from smaller loose wet slide that was set off by a skier.
