Made OBS from 4500-5400' mostly on W and NW.
Jan. 23, 2016, 1 p.m. PST
Weather: Lt. Snow and Lt. Westerly winds.
Snowpack: Dug down to Jan 3 and Jan 11 SH/Fc layers both In Undisturbed snow and disturbed locations where a widespread natural storm slab avalanche cycle running up to 700' across most of the bowl had occurred. SH now buried at 90 and 120cm and appx 60 and 80cm below new bed surfaces. ECTX on these layers although heavy taps after the 30 loading steps still produced propagation in 2 profiles in very protected spots. Rain did not percolate to these layers at elevations above 4500' and we noted that the natural cycle did not seem to step down to the deeper layers in any locations.
Area Description: CPC Yurt Zone. 2mi nw of Stevens.
Avalanches: Photo shows natural storm slab cycle with up to 40cm crowns in nw facing terrain.
