A crust has likely formed on steep solar aspects. Wind slab exists in the alpine and exposed areas at tree line. 40-60cm of settled snow overlies a layer of decomposing stellars (large new snow crystals), a crust on solar aspects, or a thin layer of facets.
The snowpack is generally strong, however the deep persistent weakness of rounding facets and a decomposed crust remains at the bottom of the snowpack.
