Went to look at east and west facing today.  West held stout crusts.  East at the higher elevation here looked similar to north facing.  

Weaknesses noted:

  • Recent likely diurnal faceted snow now buried a few cms beneath last night's inch of new and a thin wind skin.  
  • Considered facets above the Thanksgiving crust but found a good bond.
  • Facets beneath the crust and for the next 10-15cm below remains the significant weak layer.  
  • Have little doubt things will flush to or just above the ground with any significant storm.
