A large soft slab had broken out, 99% sure it was skier triggered by the skin track that I followed. It broke out on a rollover that had been cross loaded, and broke on a variation of just below the dirt layer, to just at a layer of 5mm graupel. The crown was on average 2 feet tall, the slide was approximately 250 feet wide, and broke between 300-400 vertical feet, with the debris running further. This was a NNE aspect, with a slope of 40 degrees.
I triggered many wind slabs on the ascent, all triggered on purpose. The majority of these ran on lower angle slopes on a 5mm grain size graupel.
There was much cross loading on rollovers so I would say the predominant wind was directly easterly at this elevation.
I was surprised about how active these wind slabs were, and how big of an avalanche this was (through sparse/moderate density trees). With that being said, I believe that it has begun to stabilize, but triggering may be possible tomorrow
