Comments

A defined weakness was found on the old snow interface with the snow from last Wednesday; hardness step from 4F slab above back to F in 2mm facets below. ECTP3 (Sudden Collapse). Another planar shear was also observed within last weeks snow 8cm above the old facets and failed at the same time as the prominent layer below- Not certain what this failure layer was- possibly small buried surface hoar.
