Today I went up to Habert de Chamechaude, which is a refugy just below Chamechaude, the higest peak in the Chartreuse. The difference of heigh is about 570 m in approximately 3.5 km. I leave you here some photos, among which, one panorama. Precisely, there are (from left to right) Chamrousse, Mont Aiguille, Dent de Crolles and Chamechaude.
And the panorama!
