Northern Madison, 2023-04-08

From obs 4/7/23: "...3 separate deep slab avalanches since the most recent loading event (likely 4/3). Photos are attached.... The real show stopper was on the E face of Jumbo.... HS-N-R4-D3.5-O/G. Approximate crown width of 1000ft and average depth of 6-8ft. Total run of around 2000ft. A few photos attached. other slides of note, a few D1-1.5 WL slides low in the basin SW facing. Also, an older deep slab on N facing terrain just south of Hell Roaring Lake, D2-D2.5." Photo: T. McCutcheon

From obs 4/7/23: "...3 separate deep slab avalanches since the most recent loading event (likely 4/3). Photos are attached. The first that we sighted was on the N/NE face of Jumbo. It appears to be cornice fall triggering a windslab that stepped down, HS-N-R2-D2-O @ around 10000ft on the N/NE face of Jumbo." Photo: T. McCutcheon

Southern Gallatin, 2023-04-07

From obs. 4/7/23: "I went through the area of Three Rivers Peak yesterday, and there had been a pretty nice cycle of large slides recently. One on the east face of Three Rivers broke 6-800’ wide 2-10’+ deep, and ran full track. It only had a couple inches of snow on it, so I think it ran sometime during the recent warm days. Some of the walls along the slide were over 20’ high, and I imagine the debris pile might make it through the summer. I also observed a couple older slides on E\NE aspects that were older, but not a whole lot smaller."

From obs 4/7/23: "Small wind slab triggered by snowmobile. Slope was assessed by group as wind blown before climb.  No one was caught. East facing slope, Storm castle Ridge. Photo one shows trigger point where the Snowmobiler carved hard and set off the slab deeper in the snowpack"

Photo of recent, natural wind slab avalanche near Cooke City. (which likely happened last night). The avalanche is on a SE aspect around 10,000'.  The crown looks to be about 1-3' deep and 75' wide.

Bridger Range, 2023-04-06

From obs: "South of Saddle Peak, ~8500', ENE aspect, 2-3' crown depth estimated and likely cornice-triggered. N-facing snow remained dry until the latter afternoon when a high sun angle cooked everything but the truest due north. Avalanche appeared to be all new snow likely on a PWL buried near the end of March. Winds moving snow up high, but everything appeared locked on."

Skinner triggered slide north of the hourglass. Run name unknown. Remotely triggered from ridge line; snowboarder said he was skinning 35 feet away from trigger point; no one buried. I also observed point releases as I was skinning up to texas meadows; snow seemed to change quickly under blue skies and increasing temperature. Slide ran in front of me, taking out the skin track.
