General Observations

RFS up to 3000′.  0° F, Calm, moderate snowfall.  Collapsing: Yes  Shooting crack: Yes, some radiating over 30′ through the new snow  Avalanches: Yes, small avalanches within the new snow were easily initiated were the bed surface was smooth wind board on slopes steeper than 30°.  

Found 4″ of low density snow that was very poorly bonded with old wind affected snow.  New snow had very little cohesion, but still witnessed long shooting cracks.  Also found 2-3 mm developed near surface facets with some chains just below the new snow.

Video below shows very sensitive new snow that easily releases on small terrain feature.
