The Grandes Jorasses (French pronunciation: [ɡʁɑ̃d ʒɔʁas]; 4,208 m; 13,806 ft) is a mountain in the Mont Blanc massif, on the boundary between Haute-Savoie in France and Aosta Valley in Italy.
The first ascent of the highest peak of the mountain (Pointe Walker) was by Horace Walker with guides Melchior Anderegg, Johann Jaun and Julien Grange on 30 June 1868. The second-highest peak on the mountain (Pointe Whymper, 4,184 m; 13,727 ft) was first climbed by Edward Whymper, Christian Almer, Michel Croz and Franz Biner on 24 June 1865, using what has become the normal route of ascent and the one followed by Walker's party in 1868.
