Observed multiple Na throughout the day from within 24hrs. They all seemed to be failing on the SH recently buried in the latest storm cycle. Most were easily size 2. The large alpine bowl appeared to be closer to a size 3 and possibly caused by cornice failure. The exposure at most start zones was too great to investigate further.
