Comments

We noticed a fair amount of fresh loose wet activity in the buttress area.  This wind slab avalanche under the cliffs was triggered by overrunning snow from a natural wet avalanche.  The avalanche only involved new snow from 3-22 and overnight accumulations.

Comments

I triggered a small wind slab above the crown of last week's Boiler Bowl avalanche, and I was easily able to initiate cracking in drifts.   Cracking like this is a red flag indicating potential instability.

Comments

Some neat drifting patterns from the sustained northwest wind.
