Quick report

Cracking
isolated
Collapsing
isolated

The past two weeks of slab faceting paired with significant wind erosion over the weekend have done a good job of reducing the avalanche hazard here.  We could identify only a few features of concern: recently drifted hard slabs that appear small and isolated.  Most slopes that held concerning persistent slab structures earlier this month are blown out and lack slabs, and sheltered terrain has lost cohesion, becoming just a loose pile of facets.  

Targeting obvious wind slabs that formed during the recent wind event, I produced two collapses that spanned the width of the drift, about 20' to 30' wide, 4" to 10" thick hard slabs. Other hard drifts produced some stubborn, localized cracking once I stomped around and cut into them with skis. These were mostly at valley floor, and one on a flat ridge near treeline.
