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."

PWL avalanche (R3-D2), east-facing, deep in Muddy Creek. This was drifted in and likely broke around 2.5 weeks ago during the last significant storm cycle. Photo: GNFAC

We dug a snowpit near the lower flank of the avalanche path and noted that these weak layers had gained strength over time. We did get propagation on a stout melt-freeze crust near the surface (ECTP5) but did not get propagation lower down on faceted grains. Photo: GNFAC

We saw a small north-facing avalanche in the First Yellow Mule (R1-D1) that was snowmobile triggered. It looked to be around a week old. Photo: GNFAC

"Toured up Flanders Creek to the main cirque. I was wondering what the snow surface was doing with the high pressure. I dug a pit on a NNW aspect at 8900'. HS 205cm, light SW wind, clear skies and air temp was 2.1 C at 4pm. Dust layer was down 60cm from the surface.

I didn't get any propagating results in my pit and the snowpack was right side up. I did notice a strong temperature gradient in the top few centimeters of snow. I only found this on sheltered, shaded slopes with dry powdery snow. I did not find a strong temp gradient or facets in dense wind affected snow. Something to keep in mind if we get a big dump of snow in the near future." Photo: B. Oackes

Saw a fairly fresh avalanche up Hyalite from the top of the Fat and Skinny Maids, I think that would put the avalanche in the Storm Castle Creek basin. Photo: F Miller

Another day of warm temps and clear skies allowed us to cover a lot of ground in the Southern Madisons. We rode into the Taylor Fork, up to the weather station, to the top of Carrot Basin, through Sage Basin, up and over into Cabin Creek, and all the way up to the head of Red Canyon.

There were a handful of small wet-loose avalanches on solar aspects that we noted throughout the day. While northerly aspects stayed cold, solar aspects became wet a couple inches down. Photo: GNFAC

We also spotted an old wind slab avalanche (R1-D2) that broke earlier this week in Sunlight Basin. Photo: GNFAC

On Mar 1 we also spotted one older cornice-fall triggered avalanche in Sunlight Basin. Photo: GNFAC

On Mar 1 we also spotted two cornice-fall triggered (R2-D2) avalanches that broke earlier this week - one in Sunlight Basin and one in Sage Basin. Photo: GNFAC

At the top of Carrot Basin, we saw a small avalanche (R1-D1) on a N aspect that likely broke yesterday on buried weak layers. Photo: GNFAC

Pictures of two cornice triggered avalanches way up the South Cottonwood drainage that was viewed from Alex Lowe. Looks to be in the recent days, around 9,000 feet North facing. Photo: S Lipsteuer

A massive cornice had cracked and was slowly making its way towards falling down. Cornice was around 50 feet long, and largely overhanging. Photo: S Lipsteuer

A massive cornice that has cracked and is slowly making its way towards falling down. Cornice was around 50 feet long, and largely overhanging. On the standard ascent of the East Ridge of Alex Lowe, the skin track usually travels below this cornice while ascending to the ridge. Photo S Lipsteuer
