I Did the long west normal route up Chauvet valley. very long and rocky, quite demanding, requiring some precautions up final ridge.
You have to follow the rocky glacier, left side, and arrive at a col approx 3200m on the north ridge.
From there to the top on unstable terrain.
Nice rose rocks on the summit area, the very summit is very tiny (only one person vcan stand on it).
There are other more technical routes on south face.
