Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs…) 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.
Approach from either the top of the Skyway Monte Bianco lift station or from the Aiguille du Midi cable car top station (via a skin up and across the Vallée Blanche).
The approach is shorter from the Skyway (Italian side), ski over the Col des Flambeaux and descend towards the North Face of the Tour Ronde.
Skin up around to the west side of the Tour Ronde to access the bottom of the Gervasutti Couloir.
Climb and ski the couloir and then either ski down the Vallée Blanche or return to one of the lift stations.
It is also possible to climb either the North Face or the Normal Route on the East Face and then ski/down climb to the top of the Gervasutti from the summit of the Tour Ronde, making for an elegant roundtrip.
If descending the Gervasutti 'on-sight', be sure to have a good idea of the snow conditions beforehand, since this west facing line often has very firm snow.
