5 to 10 cm snow may be covering a layer of surface hoar in sheltered areas, or a hard sun-crust on sunny slopes.
A weak layer from late January is buried 20 to 40 cm deep. This layer consists of a crust on sun-exposed slopes, and facets and/or surface hoar on other aspects.
A weak layer of facets from early December is buried 60 to 120 cm. The base of the snowpack consists of facets or depth hoar in many areas.
