Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of 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): Certain death in the case of a fall.
When you go down the Kandahar slope, after the first flat part you get to a path to go to a steeper part.
This gets you into the valley to the way down to the Cabane des Bois.
Before this valley starts you can see Mont Tubang on your left.
To access to this run you need to traverse all the way above this mountain.
You keep on going until you find cliffs just in front of you.
Here you just need to go down diagonally to the right.
There are a few rocks to avoid in the middle, and you need to be careful if you follow straight down instead of going to the right because there are cliffs at the beginning.
