Bottom Line: Strong winds will return midweek, drifting soft snow into unstable stabs. The better coverage found on wind-drifted slopes may entice us, but this is where avalanches are most likely to occur. Carefully evaluate snowpack stability and the consequences of getting caught in an avalanche with sharp rocks just inches below you.
Primary Problem: Wind-Drifted Snow

Incident details include images
Henderson Mountain
SS-N-R2-D2-O
Elevation: 10,000
Coordinates: 45.0524, -109.9450
Caught: 0 ; Buried: 0

From email 11/15/21: "east Henderson had a fresh slab avalanche- on a NE aspect around 10,000'.  It appeared to have failed on a weak layer near the ground, and I'd guess it was about 2-3' deep and 300'+ wide.  (photo attached)

Also noted some other natural slab avalanches on some northerly aspects of Miller Ridge.  (steep rocky starting zones).  And noted a couple big slab avalanches on NE erly aspects up Republic Creek too. Similar thing there:  steep, rocky, wind loaded starting zones."

Caught: 0 ; Buried: 0

From email 11/10: "noted two small cornice triggered slab avalanches on a SEerly aspect of Scotch Bonnet Mountain. They looked to be fresh this morning, involve just new snow, and were about 25' wide each."

  • From e-mail 11/10/21: "an east aspect around 9900'.  HS 63cms.  ECTV on facets at 19cms." In this snowpit the slab collapsed above the weak layer when the observer isolated the column to perform an extended column test (ECT), hence the score ECTV (ECT-very easily collapsed and propagated).

  • From email 11/10: "Wind effect: significant in most upper elevation exposed locations.  Westerly winds were moving a lot of snow off the high peaks all day today." Photo: B. Fredlund

  • From e-mail 11/7/21: "...Once in airplane bowl we saw multiple large slides that ran last night, syn-storm. Most of which came down from the East face of Sac. A few 200-300’ wide and running the length of the bowl.,,, attached is a grainy cell phone pic of the slides in Airplane Bowl." -Anonymous.

  • From email 11/4/21: "...noticed two small wet loose avalanches in the east facing bowl between Pomp and Hardscrabble Peaks." Photo: H. Darby
