General Observations

Ski tour at 6 mile/girlfriend hills.  Dug a pit at 2000' W/NW at knob where you drop in.  Found 2 layers of concern.  Buried surface hoar down 55cm( little less than 2') from surface.  ECTP 13 and PST 40/100 End.  Bottom line…YES, it failed and propagated with moderate force.  Other layer was down 155cm (5') crust/facet.  ECTX but it did propagate when I drop kicked the shovel blade.  Then PST 40/100 End.  Again…. YES, it propagated.  Main question is how widespreed or isolated is that SH layer.  As for the deeper layer, low probability with high consequences.
