Snowpack Summary
Previous strong to extreme westerly wind has scoured slopes in the alpine and formed wind slab on east facing terrain.
20 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects.
The mid and lower snowpack is generally well settled.
