The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of the skier falling.
Low Exposure (E1): Exposure is limited to that of the slope itself. Getting hurt is still likely if the slope is steep and/or the snow is hard.
Medium Exposure (E2): As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.
High Exposure (E3): In case of a fall, death is highly likely.
Extreme Exposure (E4): In case of a fall, the skier faces certain death.
This couloir starts in The Spissen Valley, rarely skied in a very remote place.
This couloir is for specialist only: it's far in the backcountry, really hard to locate and then difficult to ski in safe conditions.
It is open to the winds and it ends on a big waterfall that is tricky to bypass without a rope.
So sometimes a 60m rappel is necessary.
The line continues down the Netscho valley.
This is a journey that will bring you into the most unknown valleys if Monte Rosa, places rarely visited by people.
You will skin up large valleys climb some couloir and then skin up again before reaching this line.
So you will need to be in a excellent physical condition too.
