Northern Gallatin, 2023-12-08

From obs: 

"On descent this new snow was touchy, and we observed 2 natural avalanches, max depth 15 cm, on the small end of size 1, F hardness, running less than 30-50m exclusively in new snow. (SS-N-R1D1-N)"

"A large natural slide came down from 3rd Fork, stepped down in the Elbow and again in the cone, and ran almost to the runout of Obsidian. Naturals came out of most of the Headwaters, with both Firehole and Hellroaring stepping down into old snow in the cones."

We rode up Daisy Pass road... saw a couple 8-10" deep natural avalanches on the steep slopes above Miller Creek that probably ran in the last 24-48hours. We had multiple collapses on the NE facing slope where we ski toured to dig our second pit. Photo: GNFAC

Lionhead Range, 2023-12-03

From IG: “Skied in the lions head today on a northeast slope at 8,300 feet. Clear wind loading and reactive cornices, however storm snow was low energy with little movement. 10-14 inches of medium density snow. Whumpfing was noticed on all slopes on the eastern half of the compass.” Photo: O. Desroches

Bridger Range, 2023-12-03

From obs: "Skinned above alpine lift (just beyond the beacon checker) to get an idea for snowpack depth/ layers. A quick dig revealed a shallow, faceted snowpack!"

Cooke City, 2023-12-03

Skied around Mt. Henderson today. Was finding around 28-35 cm of new snow at 9k'. Perhaps 10cms in town. Light density.  Minor wind effect. Partly cloudy morning, turning mostly cloudy. Cold temps. Calm to light winds where I was, but lots of snow was being transported off the exposed ridgelines south of town. Quite a bit of cracking of the new snow this morning while breaking trail and while skiing, even though the wind effect was still Fist hardness.  A couple of collapses noted as well in the deeper drifts. Photo: B. Fredlund

Shooting cracks on the apron. Shallow and firm but reactive windslab breaking on the faceted layer bellow it. About 10cm of new snow sitting atop the windslab as of this afternoon. Photo: C. Bayles

Northern Gallatin, 2023-12-02

At 9,000 feet there was about an inch of new snow. It was calm at first light, but by mid morning winds were gusty and blowing straight down the gullies. It stripped what little snow there was and did not create an avalanche hazard. However, the 6+" in the gullies are all faceted, and with even a thin wind-load it was easy to get cracking. With snowfall predicted for the next 48 hours and again later this week, we'll need to be on the lookout for pockets or gullies of wind blown snow.
