Loose faceted grains at bottom 10cm of pit shot out while cleaning back wall. we did not attempt to isolate a block as the bottom was half gone from clearing the wall. The facets appeared to be rounding with the warmer temps.
Along trail at 8,200'/ 2,500m W aspect roughly 6"/ to 10"/ 25cm snow with loose facets just below the surface.
7,600'/ 2,316m Variable 4"/ 10cm to 8"/ 20cm.
Below 7,600'/ 2,316m scattered areas of large surface hoar on Northerly aspects in drainages and meadows.
We were able to split ski down the road most of the way to the car with some bare spots along the way and at the end.
