See photo below.  Phone died so no photo.  By walking off the main track and beneath this "test slope', I was able to collapse and crack out a persistent slab avalanche that collapsed and then only moved a few inches due to the slope angle.  The crack/crown along the top was plain and ran 40' across.  Aspect NE, elevation 8240'.  Collapsing in facets noted along the route from 7800' to Reynolds Summit.  

To me, I'm more interested in the outliers - what's the lowest extent of persistent slab avalanche danger? - than the more expected activity on Reynolds Peak and other "classic" terrain of mid and upper elevation shady terrain.
