Weather

Weather: Moderate winds with light transport. Clouds increased through the day with a few snow flurries this afternoon (S-1).

Snowpack

Snowpack: Skinned, snowmobiled, stomped, and skied on dozens of previously untrammeled low angled slopes without any obvious signs of instability today. It appears as if the snowpack in this deeper part of the zone is moving to a low likelihood, high consequence persistent slab problem. On a NE aspect near treeline, the slab is about 4 feet thick, mostly 1 finger hard. The 12/10 interface is 4F- to F+ 1.5 mm facets. Stability tests produced a mix of hard, propagating results (ECTP30) and propagation during isolation (ECTPV, which might have been user error).

Avalanche

Avalanches: One small natural wind slab that ran last night or this morning (E, NTL). No other fresh avalanches observed.
