East Slopes North - Canadian Border to Lake Chelan

Jan. 19, 2015, noon PST

Weather: Partly obscured morning, mostly cloudy afternoon. Light west ridge top winds, though localy, north winds. -2 to -4C.

Snowpack: Near tree line, HS hovered around 240 cm's. HST 70 cm's. Snowpack tests revealed right side up storm snow, CT12-15/ SC (sudden collapse) or Q1, down 71 below crust on 2mm facets, ECTP 10/SC. Quite the facet crust sandwich. Observed widespread collapsing and localized cracking in the storm snow in mildly wind affected areas. No interest in venturing into steeper or exposed terrain.

Area Description: Hwy 20, Cutthroat Drainage, North aspect, 6300'.

Avalanches: Widespread loose snow avalanches on all aspects in alpine and near tree line elevation bands. Observed 2, SS-R1D1/D2-N-I's on north aspects above tree line, 2, SS-R2D1-N-I's on west aspects above tree line, and one (viewed across the valley) SS-R2+D1+?-N-I on a south aspect in the alpine. Of note, this one occurred on the same slope of the reported AS triggered avalanche around New Years.
