Primary Problem: Wind Slab
Bottom Line: Wind slab avalanches are the primary problem mostly from strong winds on Tuesday and late last week that blew generally from the W and some NW. Larger persistent slab avalanches that could break on old faceted layers 1-2 feet above the ground have become much less frequent. With only light snowfall trickling in since then, the likelihood of triggering one of these has dropped significantly but the possibility remains.

Caught: 0 ; Buried: 0

Many ridgelines had been scoured down to the grass from yesterday's winds. HS was around 100cm around 8k feet and significantly shallower at lower elevations. New snow totals from the past couple of days was around 20-30cm. We experienced a remarkable number of thunderous collapses throughout the day (I lost count), one of which triggered an avalanche into Specimen Creek while we were in the flats.
