Various runs between 5600ft and 3700ft, E-SE aspects. Accessed via "winter route" to Source Lake.

Snowpack: Ski pen remains 40-45cm with an average HS over 200cm in upper TL. Favorable density profile in old HST down to 1m. Lots of deep holes and voids in the snowpack remain. Of note was a 1 cm temp/sun crust on steep, solar terrain above Source Lake that was capped by 3-5mm surface hoar and/or a thin layer of low density snow from recent flurries. This "zipper crust" was a bit variable at TL (but skied well) and especially prevelant in open, steeper terrain and higher start zones. Once buried, I would expect to this interface to be reactive on steep terrain.
Area Description: Chair Peak and Snoqualmie Divide
Avalanches: One D1 Loose Dry in on a steep, NE asp, 5800ft. Some shedding off E face of Chair and solar, cliffy terrain.
