Cold, mostly calm. Clouds lifted late AM to about 5k feet and then descended. Snowfall was intermittent and mostly light, but saw up to S2 near the White Pine area at 12p.
No new avalanche obs, aside from test slopes and a small tree bomb. Didn't have good enough viz on bigger terrain (Nason Ridge, Rock mtn, etc) to rule out those areas.
Height of snow averaged 200cm. Ski pen was 40-60cm. Trail breaking was deep and slow.
Many tests (Hand shears, informal slope tests, and CT) produced planar and sometimes very easy results on an interface ↓50cm (below 4,000ft), which I believe was buried on 12/29. See linked video. This interface was most reactive where large 4mm stellars rested on 0.5mm facets. The Solstice crust is down about 90cm and has 4F+ hard 0.5-0.75mm facets resting above it. Teperature gradients surrounding the crust were favorable for faceting.
Layer Depth/Date: 30-50cm, Jan 2 and Dec 29th
Comments: Did not observe near or above treeline
