Comments
We traveled as high as 8,300' and found a crust on all aspects, with 5-15 cms new snow on top of the crust. Above 7,500', the bond of the new snow to the crust was poor on north and east aspects, with a thin layer of near surface facets (NSF) just above the crust where shovel tilt tests produced an easy, clean shear. The NSF layer above the crust does not look like a big problem, but any wind or storm slab may be sensitive to this weak interface and the crusts will provide an easy bed surface for avalanches to run on.
