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.
Geography
The summits on the mountain (from east to west) are:
- Pointe Walker (4,208 m; 13,806 ft) – named after Horace Walker, who made the first ascent of the mountain
- Pointe Whymper (4,184 m; 13,727 ft) – named after Edward Whymper, who made the first ascent of this, the second-highest summit
- Pointe Croz (4,110 m; 13,484 ft) – named after Michel Croz, a guide from Chamonix

North face
Located on the French side of the mountain, the north face is one of the three great north faces of the Alps, along with the north faces of the
Eiger and the Matterhorn (known as 'the Trilogy'). One of the most famous walls in the Alps, it towers 1200 m (3,900 ft) above the Leschaux Glacier, stretching 1 km from end to end. The classic route on the face is the Walker Spur (Cassin/Esposito/Tizzoni, 1938, TD+/ED1, IV, 5c/6a, A1, 1200 m) which leads directly to the summit of Pointe Walker.
