Snow surface

layer of loose powder with surface hoar forming on top.


Dug a pit at the base of the upper peak on Eddies. Single column compression test showed weak layers at about 1 foot and at about 50cm below the surface (CT 27-28). We also performed an extended column test which showed propagation at the weak layer 50cm deep (ECT 27) with a clean shear all the way across. As we were filling in the pit, my partner was able to get the weak layer to propagate and release with two small jumps/stomps above the pit.
