Valley fog obscured visibility. No wind transport. Evidence of E valley winds and previous transport from 12/15.
None observed. We attempted to trigger loose dry avalanches on test slopes without luck, though we weren't in very steep terrain.
Height of snow @ 4,500ft: 70-110cm.
Coverage is still shallow at low elevations and east of the pass.
Snow surfaces continue to weaken. Found a mix of forms from very small near-surface facets, to graupel (3mm) and rimed stellars (1.0mm), and occasional needle-like surface hoar.
We weren't able to get high enough to find pre-December snow in the lower snowpack.
