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.
The snow transforms quickly in this S facing couloir so get there quickly after fresh snowfall or wait for good spring conditions.
The couloir is accessed as per Stairway to Heaven but you traverse across from the Col to reach the top of the couloir.
From the Col de Gentianes, traverse high, skiers left to the N towards the 'Stairway to Heaven' col.
Boot pack up the short couloir for around 100m.
From the col, take a long traverse line with skins on and locate the entrance to the col.
Warning: avalanche danger on the traverse and steep slopes above.
Ski the wide couloir which opens out and finishes by joining the red piste from Gentianes to La Chaux.
