The world of ski-alpinism has lost one of its most noted players with the death of Stéfane Brosse on the Aiguille d'Argentière.

With Kilian Jornet, film-maker Sébastien Montaz-Rosset and Bastien Fleury, Brosse was attempting a rapid crossing of the Mont Blanc Massif from Les Contamines in the west to Champex in Switzerland.

It was whilst moving along the summit crest [of the Aiguille d'Argentière] towards the top of the Barbey Couloir on the east face, which they planned to ski to the Saleina Glacier, that the 40-year old Brosse broke through a large cornice and fell ca 600m.
