Large areas of hard wind slab yielding hard but clean failures in stability tests, with smaller and fewer areas of soft wind slab which remains reactive, producing easy and clean failures.
Able to intentionally skier trigger the small pocket of soft . . .
We climbed and ski Diagonal, The fan at the bottom on top of the bulge was of greatest concern, hand shear pulled easily we where able to mange and avoid the area on the way up and down. The snow in the gully varied in depth from 50cm to 150cm +. It . . .
Evidence of strong NW and W wind scouring and deposition, with cross loaded pockets. Alpine terrain generally scoured to or very near to 12/3 supportable crust. In pockets of recently formed wind slab, weak layer of concern seems to be within new . . .
Toured up to the mouth of Right Gully. Carefully avoided the floor and the run-outs of Center Bowl and Chute which have reloaded with more wind transported snow. Snow was soft and very reactive in the sheltered locations low in the Ravine, but . . .
Full Profile Snow Pit. 150cm snow down to tops of krumholtz.
Unintentional skier triggered avalanche, time approximate (Saturday afternoon), no one caught or carried. Third skier on slope, a party of 3 traveling one at a time, triggered this relatively small pocket of recently formed wind slab.

Crowns observed across the right side of the Headwall, with fresh debris at the bottom of the bowl. Clear skies, no precipitation, air temp was in the negatives with wind chill. No precipitation. Strong NW wind actively transporting snow. Loading was . . .
Bushwhacked up Slide #2 for our first run, as we were hiking up we noticed a couple chunks of windslab break away. If you were standing on anything other than ice, the snow was very reactive. We decided to call it about a third of the way up, since . . .
Shooting cracks in the areas of rapidly developing wind slab.
Hand shears failing on isolation with Q1 shear quality (clean shear).
Newest/top layer of wind deposited snow, likely formed early this morning (12/7), was the reactive layer, appearing to . . .
What follows is a description of the snowpack found in Gully #1, starting in the snowpack at the Melt/Freeze crust that was supportable everywhere except in the bushes.
+The MF crust has a layer of decomposing graupel on top of it. This was found at . . .
