Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs…) 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 is the fifth couloir that can be skied underneath Testa Grigia.
It's a narrow and steep line with two rappels inside (not equipped).
It may be the most difficult couloir here because it's really hard to locate, there are rock bars that needs to be avoided and others that needs a rappel.
But it will give you an amazing view on Gressoney valley.
