Wind slabs in the Bridgers

Date
Activity
Skiing

Saw a recent cornice triggered wind slab off of Hardscrabble Peak, crown looked fairly fresh. There was a second crown line below the rock band. Conditions were very windy, with snow still being transported. Most snow surfaces were wind affected, but saw no cracking or collapsing.

Wind in the Bridgers

Date
Activity
Snowmobiling

Can confirm, it was blowing in the Bridgers.  Up high it was still cool enough that a fair amount of snow was moving around, especially further north.  Clouds of snow were coming off of the ridges and moving through the bowls near Fairy Lake and Fraiser divide.  Around the of the Throne and in the mid elevations we found better, more sheltered snow conditions.  The area around Ross Peak was very scoured.  We saw a handful of small point releases on steep south slopes, likely from Friday, but no other recent avalanche activity.  By mid-day/early afternoon, the snow lower down in the woods was getting pretty heavy and wet and anywhere with the slightest bit of sun exposure was developing a crust.  Talked to a few skiers who toured in the Naya Nuki area, and they described variable snow and very windy conditions.

Notes

Toured out to Frazier Basin and turned around seeing widespread avalanches and active wind loading. Despite our pits on the Throne the day before showing no weak layers, the amount of wind loading and potential for slabs over density changes gave us pause. Good skiing and sledding down low.

Notes

Cornice broke in between north and south saddle peaks.  The initial propagation width was hard to distinguish.  Maybe 50 feet.  About 18 inches deep at height of crown.  
 

Skied down Rocky Rib and then into south east facing trees that follow the path.  At the Argentina/ Shushmans traverse elevation there was a visible 2 foot wall and the slide had continued over the roll below.
