March 14th -16thErik StevensTakhin Ridge~6"light, variablemostly cloudyBelow 3500 feet: Top meter of snow consisted of dense soft slab with two discernable interfaces within it, one at 15cm down, another at 60cm down. Ice crust 1m down with 3cm of small-grained facets atop it. No failures on compression or extended column tests. The 1m deep layer did fail with shovel shearing, the failure plane was rated a Q3 shear.Only two small pockets of deep slab (both R1D2), both of which were likely sympathetic step-downs from lots of debris coming down over them. They were located in the middle paths of large avalanche chutes, estimated angle around 35 degrees. N aspects.Snow on some slopes was very stable with hardly any sluffing even on steep slopes.
