Saw evidence of a recent avalanche on a steep north east aspect that had propagated fairly widely (or multiple small slides occurred on the same slope). Crown varied from 50-100cm deep, although it was filling in by the time we saw it.

Jumping around on a similar aspect that hadn’t yet slid (with a rope on) resulted in lots of shooting cracks and small avalanches being released. At that location the storm snow was about 30cm thick and the rest of the snowpack was sugary facets. The snowpack here seemed pretty thin, and must have faceted out with last weeks cold snap. I also remote triggered a very small slab about 20m directly downslope from where I was stomping.
