Analysing terrain data
Judging by the multiple devil inspired names given to many of the pistes surrounding the Diamant Noir, it is a surprise that this run is not similarly named.
As one of the toughest black runs in Europe it is worth sussing it first by taking the Tête de Verds chair and then the Diamant Noir chair, to see what you are letting yourself in for.
Turning left back on yourself once off the Diamant Noir chair, the initial approach may have you wondering what everyone is scared of, and as you merrily ski the first part of the run it is easy to be lulled into a false sense of security.
And then, there it is, (and it becomes scarier later in the season) the piste having narrowed, that almost sheer vertical wall of snow and ice with moguls miraculously sticking out at right angles, which never sees the sun.
One point of imbalance, one caught edge and that is going to be one black and blue body at the bottom.
Once the wall is conquered (or been surrendered to) the piste widens but continues with wall to wall moguls.
As it flattens out a little, the moguls can be played with before the piste narrows again and winds its way down to the start of the four man chair back up - for those brave enough.
Otherwise this time hike the 50 steps up to the Desert Blanc Bar and restaurant from the top of the Diamant Noir chair lift and relax with a beer and one of the best panoramic views in the world - Mont Blanc and its range of mountains - from Argentiere and the Aiguille Vert across to St Gervais's Mont Joly.
