Primary Problem: Wet Snow
Bottom Line: Hazards associated with wet melting snow are the number one concern and they could take many forms. Loose wet slides will easily triggered as soon as the surface gets wet more than a few inches deep. The deeper the wetting gets, the larger these slides could be. The possibility of bigger, deeper, wider, more unpredictable wet slabs is also starting to become a reality. Shady slopes that have stayed dry aren’t entirely immune from avalanche hazard. You may still be able to trigger a wind slab in a wind-loaded pocket or on weak layers in the upper couple feet of the snowpack.

This afternoon I drove up Bridger canyon to Seitz Rd to see the extent of wet snow activity, and stopped in a few places to look with binoculars. There were many loose wet avalanches that ran over the last 1-3 days. I estimate they involved the upper 6-12" of snow. Activity was widespread and many slides were plenty large enough to be dangerous, but there was nothing especially remarkable about the size and I saw zero wet slabs.

Temperature was 65-70 degrees in the canyon, mostly clear skies with a few clouds, calm to light wind.

Driving home from Bridger Bowl I spotted a number of wet loose avalanches in Argentina bowl. It was 1:30 PM when I saw them and the sun was still blazing. I would expect there was more activity as the afternoon progressed.

From IG message: “Rode the banana today.. lots of fast moving sluff. Had a mid elevation pocket pop. New snow seemed to have bonded well, the spot that did pop had formed into 12” slab below rock face. Little to no signs of instability.”

  • Skiers triggered this avalanche on a north-facing slope near the Anger Lake basin.  The crown was 4-18 inches deep and propagated the entire width of the gully ~40 feet and ran the entire length of the gully ~500 vertical feet. The skier was able to ski out of the avalanche right as it broke and was not carried. Photo: Anonymous

  • From IG: Very touchy on Hollywood wall this morning. All slopes easily propagated 4-6” deep on a firm bed surface. Most were less than 50’ wide with the exception of the slide in the couloir which propagated down the entire couloir, maybe 500’ wide, and ran through the exits into the main bowl.
