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.
Ocean Drive is an excellent steep couloir for those who are willing to hike for their turns that finishes in the beautiful and wild Vallon d'Arby.
From the Col de Chassoure, start down the piste and then leave the piste to ski down and right under the chair lift.
Try to keep as much speed as possible to save on the walking.
A set of skins are useful.
Continue traversing until underneath the Col des Champs Ferret which is accessed via a short climb.
From the col traverse around the the east side / right hand side of the ridge and access the top of the couloir.
Ski straight down the couloir to the flat area below and finish as described in the Vallon d'Arby - Les Plans route.
