Snow Characteristics Comments
Above ~8500' north-facing terrain with pitch was settled, soft powder with a thin layer of 1-2mm graupel. Minimal winds throughout the storm have prevented wind-slab hazard but along 11,000' ridges we observed isolated wind slabs and small debris piles. Sluffs were only running in the upper 2-3" on northerly faces and down to the M/F crust layer on many southerlies.
On lower elevations, solar aspects and low slope angles snow had Friday and Saturday's zipper-to-death-cookie M/F crust and the sun was continuing to work. Numerous wet-loose pieces were visible from Friday-Sunday even on N-facing below 9000'. This crust may cause the next interface issues depending on the initial storm dynamics Tuesday evening.
