Traversée du Mont Pelvoux, through the Couloir Coolidge. Perfect conditions. Going down through the glacier des violettes is long and not always easy to find the route. Several abseils necessary as well. It took us about 12 hrs (we were 3 cordées)
The food at the pelvoux hut was amazing: wild boar stew for dinner and fresh croissant for breakfast, jummy.
The way up is nice and easy. Especially the way down is very nice although you need some route finding skills. The abseils are quite tricky since there are people above and below you in terrain where the rock can be lose. But the ambiance is great!
Much the same comments as below.
Difficulty : PD
We started at 4am. We went along easy rocks first, then walked up to the botton of Couloir Coolidge. The snow was in good condition, it was then easy to climb up the long slope.
We ended on the ridge that led us to the summit.
Beautiful 360° landscape. Big bright sun.
The way down is even more beautiful as you go across the Glacier des Violettes. Unfortunately, one of us broke her ankle, jumping above a crevasse. After the helicopter picked up her, a very long descent was ahead of us (be careful not to get lot, the path is not always obvious or marked by cairns).
We ended in Ailefroide at 8pm.
Long but amazing day.
A great experience in one of the greatest alpine area of France : Les Ecrins
