Combin de Valsorey

Climbed on 20 August 1857 by the Belgian-French geologist Charles Sainte-Claire Deville with four guides from Bourg-Saint-Pierre — the first summit on the Grand Combin massif to be reached. The party initially believed they had reached the true high point; only two years later, in 1859, did they return and identify the higher Combin de Grafeneire as the actual summit. The Valsorey peak is reached today from the Valsorey hut by the corridor of séracs known as the Pointe du Plateau du Couloir, a serious objective-hazard route.
