Burnier - Vogler

Approach

From the Aiguille du Midi, walk round to the beginning of the Cosmiques ridge and go up the start of the ridge. Make 6 abseils, (equipped,) down the NW face. The 1st abseil is from 2 bolts in a little pinnacle to the left of a snowy saddle, before the first summit of the ridge.
It is also possible to get to the foot of the route by abseiling from the bridge at the Aig du Midi station. The bolt hangers from the starting belay have been removed. There are still 3 older bolts and a sling with a maillon just above to the left.
