I don't think this has been reported yet, and I'm pretty sure it released mid-day, just after the snow lifted and skies cleared.  As I was skinning the ridge between E. Willow/USA Bowl, I didn't see any activity in this pocket, which released last year in this exact spot.  A couple hours later while-20 heading up towards Will's Hill, I looked back and saw that a small slab released from a steep open section, that rolls over into thick trees.  I couldn't quite make it out, but from the picture it also looks like a second slab released down and skier's R of the first slab.

Also, lots of other shallow (10-20cm) soft slabs released naturally today, some triggered by snow dropping from over-hanging trees.

And, lots of intentionally triggered soft slab activity in steeper terrain.
