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 chapel of Notre Dame des Neiges was originally intended to be built much lower down the mountain but as soon as the work began, legend has it that the materials used to build it kept mysteriously disappearing at night then reappearing up the mountain in its present location.
Taking this as a sign from above, the chapel was instead built here, in its current location.
Perhaps it is also divine intervention that the chapel sits just above a steep exciting skiing face? There are cliffs directly below the chapel but to either side of it are two very skiable faces that can be good in cold winter snow.
Given they face SE they tend to be quickly affected by the sun though so they really come into their own in spring snow.
Time your descent right and you’ll get a run that feels heaven sent.
