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.
Head out from the top of L'Aiguille lift under ropes .Follow the natural line until the route opens up.
Drop down the open couloir keeping an eye out for buried rocks.
Continue until the bottom of this obvious couloir where you pick up a track on the skier's right which brings back out onto the pistes.
