Treacherous backcountry avalanche situation due to fresh snow and snowdrifts
Fresh snow and fresh snowdrift accumulations are often triggerable by one sole skier and then possibly growing to medium size. Danger zones tend to increase with ascending altitude, particularly on steep shady slopes, behind protruberances in the landscape and in wind-loaded gullies and bowls. Particularly with solar radiation, naturally triggered loose-snow and slab avalanches of medium size are possible. Activities in backcountry demand experience in avalanche danger assessment. In isolated cases, small slab avalanches can be triggered on high-altitude extremely steep shady slopes also in the old snow.
Snowpack
The large amounts of fresh fallen snow are often being transported by intermittently strong winds. Fresh snow and snowdrifts are poorly-to-moderately bonded with the often soft layers of the old snowpack. The snowdrifts are often blanketed by fresh snowfall, the snowpack below them is generally well consolidated. At lower altitudes the fresh snow often falls on bare ground.
