Analysing terrain data
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.
An introduction to the classic Attelas couloirs.
Easily accessible adventure and steep skiing.
From Les Attelas follow the ridge NNW to the Col du Creblet (take care accessing the col - see the line on the map - at first skiers right of the ridge, crossing over skiers left, and then skiers right again to reach the col).
There are two ski routes marked on the map.
The main line from the Col du Creblet descends the main SW Facing couloir.
The couloir is fairly wide and opens out in to the main slope.
There is a steeper (more serious) variant marked which takes a more W facing couloir from the ridge before you reach the Col du Creblet.
When the couloir starts to open out you have two options.
Either head straight down the fall line to join the blue Etierces piste / continue down to Carrefour or traverse right at the end of the couloir to cross the ridge to the slopes directly below Mont Rogneux - known as "Le saut du Hans".
Warning: Avalanche risk, particularly during the diagonal traverse and on the slopes of the Mont Rogneux.
