Recreational Observation

Slot Couloir, Snoqualmie Peak

Dec. 8, 2016, noon PST

Weather: Cold and blustery. Partly cloudy with long range visibility most of the day. E'ly winds forming steady plumes off ridgelines and redistributing the low density cold snow on all but the most sheltered slopes at and above treeline, all aspects.

Snowpack: HS varies from 100cm to 200cm with a generally stable structure...at the moment. The surface ranges from medium sized surface hoar overlying a thin sun crust on S'ly to SH and near surface facets on N'ly. Many places observed are already covered by a thin skin of wind broken particles, and where this layer was thick enough to be cohesive (10cm or so) was touchy and fracturing when provoked. I was able to check this layer out in many places easily with quick hand pits, and even in areas with active loading, the low density (F) layer of 1-2mm NSF remains present more frequently than not. We decided to take the longer route over Col 4850 back to avoid a potential encounter with a recent wind slab at the top of the often used "exit notch".

Avalanches: None observed today.
