Southern Madison, 2018-03-07

This avalanche seemed to be skier triggered yesterday. The slope was located across from Bacon Rind on the east side of Highway 191. A pocket of wind-loaded snow looks to be a couple feet deep and 30' wide. Photo: GNFAC

Cooke City, 2018-03-07

A skier triggered this small soft slab avalanche on an easterly aspect at 9,100' outside Cooke City. It broke in the new snow, likely at a density change. Instabilities like this are typically short-lived...like a day.Photo: B. Fredlund

Bridger Range, 2018-03-06

Cornices across the advisory area are monstrous right now. They can break further back than you might expect and can also trigger slab avalanches on the slopes below. Give these a wide berth along the ridgelines and pay attention when traveling on slopes below. Photo: GNFAC

Cornice (CARnice) formation from light wind and low density snow in town is a clue that wind transporting snow is likely in the mountains. Photo: L. Zukiewicz

Lionhead Range, 2018-03-05

Skiers near Hebgen Lake reported: "...we did observe an isolated skier triggered slide on a steep, south facing, rocky rollover in the bottom of one of the trapper slidepaths that broke about 16 inches deep on an ice crust." Photo: A. Pohl

A skier observed this cornice debris in Hyalite canyon on Saturday (3/3). He also noted cornice separation along ridge lines.

A skier observed this skier-triggered avalanche on a NE aspect in the Maid of the Mist basin.  The crown was estimated around 1' deep. They also noted wind slabs to be touchy. Winds were gusting to over 60 mph over the previous 24 hours. Photo: J. Bartos

Southern Madison, 2018-03-02

Skiers near Bacon Rind in the southern Madison Range experienced cracking in the new snow and triggered a few small slides on steep, wind loaded slopes. Photo: M. Knotek 

Cooke City, 2018-02-28

A snow ranger from Cooke City and a member of the USGS completed the daunting task of trying to find the ground under more than 10' of snow. This pit was dug near Daisy Pass and had a depth of 133 inches. The main instabilities in the snowpack exist in the top 1-3' and mostly involve wind blown snow. Photo: M. Dixon

The snowpack around the advisory area is well over 100%. This has created a deep and relatively stable snowpack across all seven regions. 

Bridger Range, 2018-02-28

This large natural slide occurred in the bowl north of Sacagawea. It appears to be cornice triggered and involve only new and wind blown snow. The crown was up to 5' deep and slide ran full track. Photo: GNFAC 

Bridger Range, 2018-02-28

This natural avalanche on Saddle Peak occurred Tuesday afternoon after hours of strong wind-loading. Photo: G. Antonioli

Shooting cracks in the wind slabs were signs of instability off the ridge in the Bridger Range. Photo: G. Antonioli

Bridger Range, 2018-02-27

Skiers triggered this soft slab avalanche above Wolverine Bowl, north of the Bridger Bowl boundary.  The skiers noted heavy wind transport as well as cracking and collapsing along the ridge, and found that winds had also effected snow throughout the entire bowl. This slide was large enough to take a skier or rider through consequential terrain. Photo: N. Nelson 

Bridger Range, 2018-02-27

This natural avalanche was observed by skiers in the Northern Bridger Range near Fairy Lake on a NE aspect of Hardscrabble peak.  Strong winds have drifted fresh snow at many elevations, not exclusively ridge top terrain. Photo: M.Francis 

Northern Gallatin, 2018-02-22

Skiers up Mt Blackmore triggered small wind slabs near the ridgelines. These slides were small, but could produce high consequences if triggered in steep terrain. Photo: C. Ronemus 

Lionhead Range, 2018-02-21

This picture was taken on Monday, February 19, at Lionhead on an east-facing slope. The wind slab was likely triggered by a cornice chunk hitting the slope. Photo: T. Johnson

Bridger Range, 2018-02-20

Cornices have grown very large and are severely overhung. They sometimes break much further back than anticipated and can take you for a nasty, sometimes fatal ride. Plus they are excellent at triggering avalanches in the wind pillows below them. This photo was taken on the ridge north of Bridger Bowl. Photo: GNFAC
