Bottom Line: The snowpack stabilized with this week’s warm, dry weather. Look for signs of wet snow instability with temperatures in the 40s F through Saturday. Assess how new snow bonds to our existing snowpack as winter returns later this weekend.

From e-mail: "Skied in the the beehive area today. Triggered some small wind slabs that were sliding on a crust. 

E aspect 9,100': Triggered from a stomping a small cornice, which landed on a steep slope below and popped a small wind slab.

NE aspect 10,000': Triggered while skiing through a choke point. This one was thin but ran down slope quite a ways because the terrain was steeper. It was easy to avoid by skiing off to the right, since the gully was just cross loaded a bit on the left.

SE aspect 9,800': The third was just some propagating cracks. The slope angle wasn't quite steep enough to slide here.

These instabilities appeared to be confined to areas of dense wind drifted snow on top of a crust layer and did not appear to be wide spread."

  • "While skinning up to the top of Powder Park lift at Bridger, we had roughly 15' cracks propagate on an E/SE aspect. A snowpit showed roughly 8" of wind slab above a few inches of facets, on top of last week's rain crust." November 11, 2019.

  • On Sunday (11/3) skiers noted recent avalanche activity in the basin between Divide and the Maid on an east-southeast aspect. Appears to have slid on 11/2. Photo: G. Antonioli

  • A skier reported on 11/1, "Activity I observed was restricted to the new snow. A fair bit of loose snow....  Skiers on the E bowl of Blackmore triggered some D1 dry sluffage, running on a crust beneath the new snow." Photo: B. VandenBos

  • A skier reported on 11/1, "I watched a small (D1) wind slab build and fail as the wind picked up near the Blackmore/Elephant saddle (happened just before 2pm). Slab couldn't have been much thicker than 15cm, broke 30-40m wide. These slabs were building rapidly,..." Photo: B. VandenBos

  • From an email, "...here’s a pic from a north facing slope below Thunder Road, about midway up PK. We saw a few more shooting cracks in the flats below the top of PK, and the surface wind slab where this photo was taken was ~10 cm."

  • We found sensitive wind slabs near ridgelines on Mt. Blackmore and evidence of recent cross-loading. Photo: GNFAC

  • A skier in Hyalite wrote, "Natural activity that I observed was failing at new/old interface and (generally) occurred in predictable, wind loaded locations near ridge lines. The one exception is the avalanche with the freshest debris; looks like it failed right at the end of the storm in a somewhat sheltered, mid-slope location." Photo: B. VandenBos
     
  • Gusty north wind and moderate snowfall created unstable drifts of snow at Bridger on Monday (10/28). Some slid naturally and some were easily triggered by skiers. Photo: P. Hinz

  • From email: "There was 10cm of facets near the ground which led to a stable layer roughly 30cm thick. Propagation at 40cm and 50cm at 17 and 26 swings from the elbow. 22 degree slope. 25 degrees Fahrenheit. Overall snowpack was 80cm."

  • Small storm slabs triggered at Bridger on 10/26. From email: "slab formation appeared isolated to leeward sides of midslope terrain features and rollovers as well as at ridgetops".

  • From obs.: "Dug a few hasty pits and found the snowpack to be pretty saturated all the way to the ground until around 9,500ft. The upper parts of the Blackmore east face had well over 3ft of snow, and was still dry and faceted at the base. Picture is a pit from around 9,700ft on Blackmore... 115cm deep. Wet snow made up about 2/3rds of the snowpack, on top of a sun crust with dry basal facets below." Photo: C. Kussmaul

  • Large avalanche observed on 10/25 near Imp Peak in the Taylor Fork.

  • Snow available for transport in the Bridgers is isolated to upper elevations, as mid/lower the snowpack was wet and warm. Skiers recent activity on Saddle isolated to fresh cornice fall and loose snow sluffing. Photo: G. Antonioli

  • The snow still available for transport is isolated to upper elevations, as mid/lower the snowpack was wet and warm. Skiers noted recent activity on Saddle isolated to fresh cornice fall and loose snow sluffing. Photo: G. Antonioli

  • A local near Fairy Lake gets a taste of fresh October snow and wind. "You know it's somewhat windy when the goats start closing their eyes and their beards get blown sideways." Photo: B. VandenBos

  • Dry loose snow avalanches were observed on 10/10 as the recent snow settled. From e-mail "...saw some small, solar-initiated, dry loose snow slides in steep, rocky terrain (heads up ice climbers). With a firm surface beneath the new snow, these little guys were picking up steam quickly." Photo: B. VandenBos

  • Avalanche debris on the saddle near Hyalite Peak. This is indicative of the type of heavily wind loaded terrain near ridgelines where avalanches are most likely this time of year. Photo: B. VandenBos

  • Skiers on Thursday (10/10) morning reported, "touring up to Blackmore’s east face we found a shallow snowpack that is already showing a few widespread layers. The bottom 5-10cm was weak faceted snow overlaid by 5cm of a sun crust/Ice layer. On top was a few inches of new storm snow. We found the snowpack to be about 30cm’s deep in Blackmore’s east basin at around 9,000ft and above." Photo: C. Kussmaul

  • Broken off cornice on the saddle between Blackmore and Elephant on 10/5. "Snow was anywhere from inches deep with grass and rocks to hip deep. It was mostly knee deep though. Down in the flats below the bowl there was easily 8-10" fresh and another 2" on my way down..." Photo: @benjacobsenphoto

  • Ice Climbers on the Sphinx sent this photo from October 3, and noted,

    "No snow hazard of much concern on the approach. However, a quick hasty pit in an isolated wind pocket revealed a CT1 on this layer.  ice axe is to the ground." Photo: S. Magro

  • The mountains got their first coat of snow at the end of September, though it isn't quite enough to protect you from hitting rocks. Where the snow is drifted provides the best coverage, but is also the most likely place to trigger a small slide. A small slide would be painful if it pushes you into the many exposed rocks.

  • We hiked in to put up the Flanders weather station on 9/25 and found a spotty distribution of 4-6" of snow above 8,000'. Photo: GNFAC

  • Last weekend (9/23) there was about 14 inches of snow at 9,000'. Sun and warm temperatures created wet snow avalanches on slopes that face the sun. These small slides can be hazardous if they push you into the wrong terrain. Photo: Z. Drobnik
