Snoqualmie Pass

Feb. 22, 2017, 3 p.m. PST

Weather: S-1, low clouds coming and going during the afternoon, no wind.

Snowpack: 5-10cm new snow of F hardness consisting of rimed stellars and graupel over a 4F hardness storm layer from 2/20. This layer had become crusted over up to about 5000ft, making for a somewhat punchy feeling snowpack. Failures were below this 2/20 layer on drier (F+) old snow, all above the Valentines day crust.

Area Description: Source Lake area

Avalanches: Intentionally triggered 2 small, steep pockets (D1) up to 20cm deep x 8m wide on S to NE aspects above 4500ft.
