Cloud cover increased and snow showers began at noon.
Very small loose dry avalanches ran in previous days from the steep north facing cliffs by the lake. One outlier slab avalanche ran off a very steep, cliffy feature in the same area, which climaxed on a rock face, D1.5. Rollerballing had also occurred in recent days.
The most impressive finding of the day was the abrupt change in snow depth, from patchy snow at 2000ft to a consistent 6ft snowpack at Lake 22, at approximately 2500ft.
I dug a pit on a west-facing aspect on the shores of the lake, and found a well-consolidated dry upper snowpack, broken up with a few crusts. The 4/8 layer was still moist and soft, about 30cm below the surface. A thin coating of surface hoar was present on the surface, mixed in with stellars and decomposing forms.
