Had lots of cracking throughout ski tour and some small shooting cracks in isolated wind loaded terrain.  Many hand pits revealed easy shears between the new snow/old snow interface.  At my profile location no propagation was seen at the new snow/old snow interface but there were several results at the12/21 rain crust, my profile location was below treeline and had limited wind loading.  I ski cut many small slopes with little to no results at all elevations and aspects.  The upper bowl on Silver Peak had no evidence of any activity or debri.    

Photo#1: Small natural avalanche crown line just visible with some debri showing down lower but mostly covered up by new storm snow and wind loading.  North facing wind loaded, estimated around 40-42 degrees at 7000' in Silver Creek drainage.

Photo#2: Small skier triggered wind slab in small gully.  Slid on new snow/old snow interface
