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 lies skiers right of the classic Grand Couloir.
This line is still relatively direct but is steeper and more exposed - a fall here could be very serious.
It starts slightly to the right of the main Grand Couloir.
As with the other Trifides couloirs, the line can also be accessed from the line of the disused Dome/Trifides drag lift by taking in the couloir above.
