The Jan 17th layer is down 20-40cm and consists of surface hoar in sheltered areas and sun crust on steep solar aspects. This layer seems more problematic between 1600-2100m where soft slab exists, human triggered avalanches remain possible.
Use caution on open slopes and convex rolls where buried surface hoar may be preserved.Dig down to find and test weak layers before committing to a line.
Aspects: All aspects.
Elevations: Alpine, Treeline.
