Crown of avalanche that was triggered by a group of four skiers. Two were partially buried (1 injured, 1 killed) on 1/25/19. They were all ascending and near the top of the path when the avalanche broke. The top two skiers held onto trees as the avalanche pushed by them. Photo: GNFAC

Looking uphill from where the victim was partially buried against a tree. A group of four skiers were caught, and two were partially buried (1 injured, 1 killed) on 1/25/19. The other partially buried skier was 200' lower. They were all ascending and near the top of the path when the avalanche broke.

Debris from a large natural avalanche on the West side of the Bridgers behind Bridger Bowl on morning of 1/24. The debris has a lot of small trees that the avalanche broke and carried to the bottom. Photo: BBSP

Skiers up the main fork of Hyalite Canyon experienced collapsing and shooting cracks on an east facing slope at 7.300 ft. Photo: M. Tepfer

A foot of new snow and strong west-northwest winds are creating dangerous avalanche conditions on wind loaded slopes. Facets near the ground are gaining strength, but slides failing this layer can't be ruled out. With more snow and wind on the way, the avalanche danger will remain elevated. Photo: GNFAC 

Northern Gallatin, 2019-01-24

A skier noticed multiple collapses at History Rock, and snapped a photo of active wind loading at higher elevations in Hyalite. From the email: " Roughly 30cm new snow from the last storm, light winds, although Blackmore (pictured) and Flanders appeared to be getting hammered by the wind. Did a few laps in the top meadow and was getting frequent collapsing on the way back up. One felt like a small earthquake and was the loudest wumpf I've ever heard." Photo: M. Lavery

A skier in Hyalite reported many signs of new snow instability near Mt. Blackmore. From the email: "Widespread shooting cracks and wumphing. Lots of dry loose activity in steep terrain. I saw what I believe was a crown line near the ridge on the north face of Blackmore but it was hard to see because it was in the shade. The wind was gusty and not very consistent, so those wind affected slopes didn’t appear to have set up into harder slabs yet, but I wasn’t about to walk out there to find out!" Photo: H. Coppolillo

A skier on Mount Ellis reported poor structure and unstable test results today, which was good enough reason for them to follow the skin track back out. They also noticed localized collapsing in the thinner snowpack at lower elevations. Photo: N. Truax

Bridger Range, 2019-01-24

Avalanche on west side of Bridgers behind d-route at Bridger Bowl. Ran full width of path and over the ice climb well into the flats across summer trail. R4-D3. Crown extends out of left side of photo (marked by red arrows). Avalanche ran down the paths in the foreground as well (marked by black arrows). From the ridge late this morning (1/24) we saw multiple large crowns on the west side behind Bridger Bowl. Broke naturally, probably overnight after 1.6" of swe yesterday and moderate westerly winds. Photo: GNFAC

Skiers got collapses and cracks as they toured up Lick Creek. They reported, "1 large whumph on 26 degree NE terrain @7600’. Investigated and likely weak layer was 3-4 mm facets down 70cm with total HS 105." Photo: Z. Keskinen

A skier north of Bridger Bowl observed this small avalanche on Tuesday, January 22nd. It's unclear if the side was triggered by a skier or a natural. It appears to only involve new and wind blow snow. Avalanche activity is the number one sign the snowpack is unstable. Photo: M. Murphy

From an email:

"...was riding with a group near the Two Top area and remotely triggered this slide as rode past this drainage on the top of the ridge. It was a north facing wind loaded slope in the 38 degree slope range. It broke about 12 inches deep and looked like it was from the last snow/wind loading." Photo: J. Norlander

From an email:

"Dug a pit at ~9000’ on a NE aspect, got a ECTP29 at 56cm down, breaking below the new snow and a 12cm knife-hard slab. Broke on small facets (<1mm) in between wind slabs. I marked the trigger point in red. Skinned up a low angle gully up to around 9500’. As I got near the steepest part of the gully (38°), a soft slab 12-18” thick propagated 100’ wide and slid 500’ back down to my pit. No one was caught. Contrary to my pit, this ENE aspect slid just the new snow on top of a previous wind slab. No facets on the bed surface, just new snow/old snow interface. Found safer skiing down low in the trees where there was less wind loading." Photo: M. Cohen
