More detailed information about the snowpack: 

Toured up big pine canyon today to about 10200’ today on the SE side of Mt Alice.  Temperatures were quite warm today with intense solar input and very low winds.  Surface conditions were in somewhat of a transitional state.  As we began our ascent of the SE chute around 1030 surface conditions had softened quite a bit and we were able to keep our skis on to about 9600’.  By the time we transitioned to ski at about 1230 about 2-5 cm of the surface snow was saturated from the warming above 10000’.  Some of the best skiing today was on supportable wind board that has turned to pseudo corn snow.  Areas with more unconsolidated surface snow has not yet consolidated enough and could be described as a mankey. 

Some roller balls were noted as well as some actively shedding cliffs.  We also observed a couple of loose wet slides that appeared to have run recently though we did not observe any today.  no other signs of instability were observed on our tour today.
