From IG mesasge (4/6): "Some wet action at arange peak near Sawtell yesterday. From slope Dave and I did our first pit on Monday. Lots of release in that new old interface but didn’t see anything releasing down deeper." Photo: Z. Bailey

Riders saw this recent storm slab avalanche while riding near Fairy Lake. This avalanche was triggered by riders not in their group. Photo: Anonymous

Skiers in the Love Chutes triggered this avalanche after a ski cut produced no results. Further down the chute, the first skier triggered an 18" wind slab avalanche. They were carried 200' before self-arresting and were uninjured. Photo: Anonymous

While ski touring in Frazier Basin we saw at least 12 recent loose wet avalanches on east and south aspects. Most of them started near exposed rocks and entrained the upper 6" of wet snow. Photo: GNFAC

We rode from the Buttermilk trailhead up Denny Creek to Lionhead Ridge, along Lionhead Ridge through Watkins Creek and to the motorized boundary at the head of Targhee Creek. 

There was a ~1" crust at the surface when we left the trailhead, with dry snow beneath. We saw our first wet loose avalanche of the day running around 11 am. By 12:30 there were dozens and many rollerballs. None of them ran particularly far or picked up too much volume.  The snow surface was moist on sunny slopes by late morning, but not more than a few inches down.

We saw one small slab avalanche that occurred since this weekend's snow. It appears to have been triggered by a snowmobile yesterday (4/1/24). It broke 10" to 2 ft deep, 50 ft wide, and ran ~50 vertical feet. It broke on a thin layer of facets beneath the new snow. Digging in the crown, dry facets at the ground were along still present and weak (fist hardness).
