Comments
Column tests and ECT testing showed multiple week layers in the upper 18" of the snowpack. Failures were from the elbow and of Q2 shear quality. I think these will settle out relatively quickly. ECT and CT results still reflect the deep slab instability we have. Even though it is harder to get them to fail, they are shearing cleanly and with energy. ECTP25 - fractures propagated the length of the column. About 42" of snow at 9800'.
