From IG 2/10/24: “Multiple avalanches in the northern lions head on the eastern half of the compass. All were at around 8,500 feet.”
From IG 2/10/24: “East aspect, southwest of island park from the blue creek trailhead.”
Snowmobiler triggered an avalanche. She climbed up the backside of Crown Butte and as she descended the slope the avalanche broke and ran down the slope behind her. No one was caught or injured
Went for a little jaunt up History Rock this afternoon. Had two small localized whumfs near the top of the E facing meadow. Up to 20cm storm snow over a (mostly) supportive crust over facets. In the N facing meadow this crust was thin (<1cm) and breakable.
From email on 02/10/2024: "Yesterday, I skied a few Submarine and a few Woody Ridge laps. Collapsing/shooting cracks were widespread and thunderous. Snowfall totals seemed closer to 12” unsettled, with minimal wind. Biggest collapses were near the ridgecrest (1st pic was an impressive shooting crack)."
A natural avalanche on Woody Ridge likely broke sometime between the afternoon 02/09/2024 and 02/10/2024. The reporting party skied in this region on 02/09 and did not see this avalanche. On 02/10 they reported continued collapsing and cracking as well.
Skiers on Woody Ridge felt numerous "thunderous" collapses and saw shooting cracks during their ski tour on 02/09/2024. Photo: N. Stayner

Today heading up Republic, we observed the crown of a recent avy on Woody Ridge north (pic 2). I wondered for a sec if I had remoted it yesterday but I was further south. The avy looked to originate around 9800’ on a west (slight north) aspect in rocky terrain. Appeared natural from what we could see from the drainage.
We skied a zone south of woody proper, and had less but still pretty regular collapsing and cracking, though steep tester slopes were nonreactive to ski cuts, surprisingly. Still very little wind. "
From obs: "Member in our group was on the flank of the slope. Crack shot from beneath sled and triggered the slope from ~ 100’ away. Broke about 75 yards wide, ripped to dirt and travelled a short ways to toe of the slope. North facing, 9220’"
