Snowpit Observations
More detailed information about the snowpack: 

Pit dug near starting zone of steeper rocky area near top of Punta Bardini.  See attached.  2 extended column tests done, no simple compression tests.  Both ECT tests failed on 29 taps near the top of the basal facet layer near the ground (Q1, Sudden planar, quickly popped and slid off, did erode underlying facet layer upon sliding so resulting fracture plane was rough).  Snow depth 140cm, failures occured 110cm below surface.  Pit was dug (unintentionally) above very rocky ground, with larger rock outcrop just above pit that was under snow surface.  Very represenstative of a possible trigger point, but perhaps not representative of the overall slope.  More pits would need to be dug, but recent reports suggest a weak basal facet layer is widespread across Punta Bardini.  It is unlikely that a skier/boarder could trigger this layer in a spot where it is >1m deep, however, it could be possible at a spot where a shallower overlying snowpack exists.  ECTN on one test about 30cm down from surface.  

Lots of ski tracks throughout, this has been a popular area at the moment.  No evidence of natural or human tirggered avalanches (except for some old debris on uphill side of trees part way down main bardini chute).    

Overall surface snow encountered is unconsolidated and un-wind-affected top to bottom.
