We took a late afternoon trip to the north end of earthquake dome to check conditions and dig a pit.  Skies blue with dead calm winds. Air temperature 4 degrees C.  Stayed generally low on the slope and found snow depth HS to be between 80 and 100 cm below elevation of 8500 feet.  Snow surface was typically soft in the trees with a minor crust in more open areas.  Our pit showed 3 new snow from last night lying upon 25 cm of 4F faceting rounds.  This upper interval skis well where not tracked up and where not affected by the tree bombs.  Below the upper 28cm lies a 4 cm thick crust of Pencil hardness.  This crust was the most significant layer in the pit.  Below the crust the pit exposed pretty bomber snowpack of faceting rounds 1F hardness firming up to P hardness down to the ground surface.  Snow surface -3C, mid-snowpack -6C, snow at ground was -5C.  Our column test showed an unimpressive Q3 failure after 21 blows (CT21) atop the crust 28 cm deep.  Our ECT test showed no result (ECT X).
