Jan. 27, 2016, 8 a.m. PST
Weather: Overcast or obscured all morning as the clouds lowered below ridgetop. Winds were light and var. in the BTL and NTL terrain I was in. At 0815 at 61600' Tair: 4 deg C.
Snowpack: HS: 180-200cm. Upper 20cm wet snow going DF to MF. Saturated layer down 20cm, 2cm thick, maybe pooling on a crust that is now melting. Dry snow below this. 1/11 SH is down 50-60cm, 1/3 SH down 55-70cm. SH layers produced consistent ECTP results. Pinwheels were rolling well to about 60cm diameter. On wetter aspects stubborn loose wet could be cut with skis. At 4600' noticed a road cut with lots of buckling and a wide open glide crack.
Area Description: Stemilt Basin, NW rim of basin. Obs from 6100' to 6400', N-E aspects.
Avalanches: Looked at one of the avs, mentioned here by Jamie Tackman 1/25, from the last natural cycle a week or more ago. This one was 30m x 30m, 55cm deep, went on 1/3 SH. Slope at crown was 32deg, but rolled to >35deg below.
