Snowpit Observations
More detailed information about the snowpack: 

Toured off the back of June Mtn today and up and down the SE aspects of the Negatives.  Warm day, full sunshine (a couple high clouds cleared by 9:30am), calm winds except for occasional light gusts at the ridgetop at 11,000'.  ~5-10cm of Moist surface snow over firm crust from 10,500' to 11,000' between 10:30-11:00am.  Crampons quite useful.  11:30 descent time was good for supportable spring snow skiing on E to SE facing slopes.  I did trigger a small loose-wet slide with my second turn off the ridgeline on a steep East aspect that flushed thru a narrow choke between rocks that would have been plenty large enough to take a skier for a ride and bad fall had they been below the start of the slough ... good slough management is key in steeper terrain this time of year.  No sloughing issues for the rest of the ski.  The snow in the northerly facing Devil's Slide from 9000' - 7400' at 12:45pm remained very supportable to the bottom, and varied from firm to soft depending on the subtle sidewall aspect changes.   Impressive amount of tree and branch debris in the bottom run-out from what was obviously a very large avalanche this winter that likely occured during the huge storm at the end of January.
