Natural storm snow avalanche in Hyalite

Natural avalanche activity was widespread in Hyalite on Tuesday 11/6. Obs from e-mail: "The newest snow (about 18", I'd guess past 48hrs) is touchy soft slab. The top 8 inches also exhibit a storm slab-like quality.  There appears to be a very slight density change between the two.  Top 8" fracture and propagate cracks readily on gentle terrain, whereas in steeper terrain, the deeper slab (again, about 18" down) was propagating as I was skinning up the headwall in the steep creek drainages and steeper features nearby. Lots of natural activity on steeper terrain, but vis was limited.
