Comments
Our observations today were limited to low and upper elevation terrain. Southerlies and northerly aspects. All areas we traveled we experienced collapsing and the presence of the November PWL. The ony differance was overall snowpack depth and depth of the PWL.
A noteworth 5 star day today! Calm winds and crystal clear skies made for a stellar field day for our first ever Motorized/Human Power AIARE 1 course. Snow lingered in the trees tipping us off that the winds have been realtively well behaved.
Big takeaways is the PWL is very much reactive as we saw in our pit and has all the ingredients for a large and dangerous avalanche.
