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.
