Avalanche danger above the treeline is moderate. The main problem is freshly generated snowdrift accumulations which can trigger a small, and in isolated cases also a medium-sized slab avalanche even by minimum addiitional loading. Danger zones for slab avalanches occur particularly in NW/N/SE facing slopes and in steep ridgeline terrain. Above 2400m an avalanche which is unleashed on the surface can fracture down to deeper layers inside the old snowpack In very steep, unstructured terrain below 2200m, isolated naturally triggered glide-snow avalanches can unleash. Avoid all terrain below glide cracks.

Avalanche danger in generally low, but isolated danger zones occur due to freshly generated snowdrift accumulations.
Snowpack
The small amount of fresh fallen snow and fresh snowdrifts often blanket surface hoar or else faceted old snow and can be prone to triggering. The snow base is often quite shallow and in isolated cases is weakened by faceted layers on shady high-alpine slopes.
