Lots of snow and blowing snow with gusty winds picking up by 3pm. Storm slab was cohesive and seems to be sitting atop a crust that was only to be found on certain slopes (namely, southeast).
Accidentally triggered a slide on a couple of convex slopes (you know, the kind they mentioned avoiding in the forecast) that tipped up into the upper 30's for slope angle. In the more significant of the two, the storm snow, which seemed to be sitting on a supportable crust on certain aspects in the zone we explored, released, propagating about 100' across the slope. The slide ran at a boot's depth, without much impact, never gaining much momentum or speed. We estimated the crown to be between 6 and 10 inches.
