Sky cover increased and visibility decreased as day progressed. Very light flurries began at approx 1230.
We saw one large avalanche on a distant peak which probably ran in the last two days (photo). It was unknown what layer it ran on. It was at approx 4500ft, facing NNE. We saw one additional large avalanche which was very difficult to detect as there was at least a foot of snow covering the crown/debris. It probably occurred early morning on 1/3. (4100ft, NNW)
A pit at 4600ft, S aspect, was 220cm deep. Our main concern which we found there and in several other hand pits throughout the day was resistant failures approximately 20cm down in a graupel layer (CT11 RP). The other notable concern was a thin (5mm) surface hoar layer found about 65cm deep in two different locations we dug. Results were CT28 RP and CT30 RP on that layer. The Solstice Crust was down 140cm (wind affected), and we did not find any weakness around that layer.
