Dug 2 pit near each other down to 80 cm from ground. Two crust are visible, at 100 cm and 150 cm from ground. Surface new snow (20cm) was not well bonded as expected. Column test showed no weakness on first pit. Second pit failed at 26 tap at 50 cm from top (not on a crust) Shear test (sawing above 150cm crust) didn’t show any weakness either
