Bridger Range

(Apr 5 ) "Observed multiple D1-1.5 natural dry loose avalanches (and some tiny wind slab pockets under the ridge cornice) that likely occurred during peak warming around 2-3 PM. North/sheltered aspects from ~9- 8.5k held an average of 8+ inches of dry, drifted snow...." Photo: G. Antonioli

A snowobarder tagged us in an IG story of triggering a long running, powerful wet loose slide in the Bridger Range.

We went on a tour in the Bridgers today, we ascended the east ridge of Naya Nuki to the entrance of the Great One. Wind was blowing and we were being careful about potential wind slabs up high.

Skier 1 ski cut the top of the chute and produced a small wind slab that ran to the break in the chute and continued another 100 vert down the east apron. After all meeting up halfway down, skier 2 proceeded to ski the E facing apron. A wind slab propagated and carried skier 2 roughly 300 vert down the apron where skier 2 was able to swim out of the fall line and came to a rest on top of the debris. Everyone was okay aside two missing ski poles.

On the way out, we saw a few more small natural wind slabs that broke naturally near ridge lines as well as point and release wet slides.

From BBSP: " At 2.45?pm a... solo skier triggered a wind loaded pocket on the main face of Saddle Peak that ran down over the cliff and produced an impressive powder cloud.... I met him... and confirm he was alone and no one was in front of him. The avalanche looked to be 2' deep on the southern flank and 5" deep on the northern flank... It entrained more snow on the way down, one 2' deep downhill wind loaded pocket and some loose wet snow. It ran into the bottom of the going home chute, gouging a large hole and then 100ft downhill left a 200ft by 30ft wide shallow debris pile."

Observed multiple D1-1.5 natural dry loose avalanches (and some tiny wind slab pockets under the ridge cornice) that likely occurred during peak warming around 2-3 PM. North/sheltered aspects from ~9- 8.5k held an average of 8+ inches of dry, drifted snow. Early AM to mid-afternoon, very active wind transport followed by tapered winds and a rapid increase in temp. Also observed one small wind slab occurring between Saddle & the Football Field, possibly skier-triggered.

There was a pair of R1, D1 avalanches on Saddle Peak. One appears to be a loose snow avalanche triggered by a skier coming off of north Saddle Peak That ran a couple hundred feet. The second was a small slab coming out of Spencer’s with debris running into Going Home Chute. Photo: GNFAC

I was skiing in bounds on Slushman’s lift and saw a pair of R1, D1 avalanches on Saddle Peak. One appears to be a loose snow avalanche triggered by a skier coming off of north Saddle Peak That ran a couple hundred feet. The second was a small slab coming out of Spencer’s with debris running into Going Home Chute. 
 

There were many tracks across the visible Saddle Peak terrain. 

In one steeper roll over, I got shooting cracks and a small storm slab to break at my ski tips. Photo: GNFAC
