Dent du Géant, Mountain summit at France-Italy border, Mont Blanc massif

The Dent du Géant is a rock summit on the France-Italy border in the Mont Blanc massif, rising to 4,013 m. It has two peaks about 27 m apart: Pointe Graham (4,013 m) and Pointe Sella (4,009 m), separated by a small col. The higher north-east peak is a slender spire of pale grey rock, while the south-west face drops toward Val Ferret.

The summit was first climbed in 1882 by William Woodman Graham accompanied by Alpine guides Auguste Cupelin and Alphonse Payot. This ascent marked an important moment in the climbing history of the Mont Blanc region.

The name means "giant's tooth" in both French and Italian, after the slender rock spire visible from the Chamonix and Courmayeur sides. W. W. Graham, climbing Pointe Sella in 1882, found the letter "M" carved on a rock step by one of the Maquignaz guides. The two summits, Pointe Sella and Pointe Graham, are named after the Sella family clients and Graham himself.

Climbing this summit requires technical rock climbing skills and proper Alpine equipment. Most climbers start from the Torino Hut, and the ascent should be attempted only during stable weather windows.

The two summits stand 27 metres apart, separated by a notch W. W. Graham called "extremely awkward". On 20 August 1882 Graham's party used the Maquignaz fixed ropes to repeat Pointe Sella, then lowered themselves 12 metres into the col to reach the higher Pointe Graham. Graham noted a letter 'M' carved by one of the Maquignazes on a rock step.
