More detailed information about the snowpack: 

Human triggered and natural storm slab avalanches.  We got a lot more snow than was forecasted.  1 to 2" an hour snowfall rates during the day.  Snow was starting to really pile up.  Colder low density snow feel during the early morning hours.  This was than being buried by warmer more cohesive snow that was showing a propensity to propagate. (See Graham's Video).  Visibility wasn't great but we did see large avalanche debris from a NE Aspect Above Treeline that had run into the flats.  We suspect that this stepped down into older layers probably below that recently formed wind slab from Thursday.
