Skier triggered wind slab on Northeast slope at 7,450 feet elevation. One skier was caught and carried roughly 10 feet before the slide came to a stop.

We also witnessed a falling cornice today that washed some snow through rocks. Be aware of what's above you.

From obs: "Multiple natural loose avalanches in the steep terrain of mt Blackmore. All originated at the base of cliffs or trees. Counted 4 prominent ones."

From obs: "Looks like a recent naturally triggered slide towards the Idaho wilderness boundary on lionhead."

Mar 7 obs: "...There was 6" of low density snow from yesterday. Winds were stronger than expected, from the north at the top of the Throne, and increased through the morning.... We found fresh drifts that were reactive, cracking easily and 5-10' wide out from our skis, on south and east facing slopes around 8000-8300'." Photo: GNFAC

Mar 7 obs: "There was 6" of low density snow from yesterday.... The new snow was low density and sluffed easily on steep shady northerlies. On steep slopes facing the sun (south and east, and probably west) the new snow sat on a crust and became moist as the sun warmed it up and started to slide under skis. We saw a couple very small natural loose snow slides below rock outcrops on south facing slopes. Air temperatures were well below freezing, especially with wind chill, but the sun quickly warmed the recent new snow." Photo: GNFAC

Above Goose Creek -hard, dense, strong, and deep snow. Facets from late January are 1F+ hardness

Saw lots of small loose avalanches on Mt Blackmore and nearby slopes, some appeared to be natural and others skier triggered. We saw multiple dry loose on N and E aspects and a wet loose on a southeast aspect. Photo: H Meyers

Toured into the emigrant gulch area today. At around 7600’, I found some touchy storm slabs. These only seemed to be reactive on solar aspects (crust). Photo: J Alford

Came across a old slide in the hell roaring drainage heading towards Gallatin.  East facing. Happened sometime before the recent snow but not long ago. Initial crown seemed to be 12-18 inches and stepped down further down the slope. Was a fairly large debris pile. Photo: S Knowles

Old Avalanche spotted from Wilson yesterday looking  North. Possible cornice fall trigger during the warm up but difficult to tell as it was quite a ways away.  Photo attached. Photo: Anonymous

From obs on 3/4/25:

"Saw a few sluffs in the new snow triggered by skiers in the very steep terrain just north of the Bridger Bowl ski area boundary (see photo). These sluffs were small, definitely not large enough to bury someone."
