Mainly clear, but low-level clouds obscured skies 1300-1500. Intense long wave losses kept surfaces cool (aside from brief obscured period) on all aspects.
40-60cm of new snow are over the Xmas crust 5000-5500ft, and total snow heights averaged 1.5-2.5m at those elevations. At 3000ft about 2ft of snow was present, which is approximately where the snowline for the post Xmas snowstorms began accumulating.
In the several pits we dug we found that the previous few days' weaknesses within the new snow layers above the Xmas crust had strengthened, although we were not on notably wind loaded areas to test them.
Intense solar input moistened southerly slopes ~20cm deep midday. A subsequent thin crust formed as the sun's direct angle left the slope. Rollerballs occurred. We saw one natural D1.5 wet loose avalanche on a steep SW slope. We triggered one wet/dry loose D1 in the afternoon in a steep, tree-covered gully area that had about 15cm of new snow over Xmas crust, running down the gully on the crust interface. Approx 4500ft.
Impressive old glide cracks/avalanches were identified on the SE slopes of Cowap Peak, likely from Xmas warming. Now covered by ~2ft of snow. It was difficult to determine what they were at first. Photos didn't do justice.
