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.
Start by walking up the iron steps to the top of the Grands Montets viewing platform.
You then need to climb over the metal barrier on the N side of the platform and scramble round the rocks on a flattish and then downward traverse round to the left then back right, often with a fixed rope at the end to get down to the snow.
Early season and after a big storm it can be easy bootpacking in the snow but it is often icy needing crampons.
The traverse is fairly easy but very exposed! You are on a glacier so make sure you are equipped, prepared and have practised crevasse rescue, however unlikely you think falling in a crevasse is- it is possible! A minimum would be each person to have harness, axe, crampons, an ice screw, 3 prussiks, several screwgates, a pulley/DMM Revolver karabiner, a couple of slings and 2 30m ropes in the group.
A more modern simple solution substituting for many of the above might be 2 Petzl RAD systems in the group.
If you have any doubts about this ski with an IFMGA Mountain Guide.The line itself usually lovely cold snow, steep initially with a small convexity but soon eases off and is over almost too quickly putting you onto the Pointe de Vue piste.
