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.
This is a great line, committing and steep.
You need good snow cover to the valley floor to consider it.
From the top of the Plan Joran lift follow the Marmottons Variante piste which doubles back on itself.
As it passes under the cables of the access lift turn R with the cables overhead.
This rapidly steepens up and is a narrow passage between the trees- it is a clearing of the old chairlift that used to lie here.
You don't follow this all the way down but instead you need to traverse out L a short way down to enter the main Couloir de Jeureumaz line, that itself descends directly from the Plan Joran restaurant.
In exceptional conditions you can access it that way too.
Follow the main gut of the couloir, which bends to the L in its lower section, before opening out in the Chosalets beginner piste area.
Diagonally R past some chalets will lead you to the cross country pistes and the access lifts where you started.
