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 alternative to the Pré du Bois tree lines, the Echaillon is no less steep, exciting or challenging.
It’s entrance is to the right, NE, of the Echaillon restaurant and once in it you can follow it down to the Bois red run which in turn leads to the bottom of the Pré du Bois button lift.
If you cut right too soon as the couloir widens, be prepared for some airtime.
There are cliffs to the right that are jumpable if there is lots of snow but the landings need to be precise as there are numerous obstacles in the form of trees and rocks that will check your speed for you rather dramatically if you don’t do it yourself.
If in doubt, stay in the central line.
