Aiguille de Rochefort

Mont Mallet (3,989 metres (13,087 ft)) is a mountain in the Mont Blanc massif in Haute-Savoie, France. It lies on a spur running northwards from the French-Italian frontier ridge, and can be most easily reached from the Aiguille de Rochefort. Mont Mallet was first climbed on 4th September 1871. The first ascension party consisted of Leslie Stephen, Gabriel Loppé, F. Wallroth, Melchior Anderegg, Cachet and A. Tournier. They reached it via its southern ridge, a route now graded on the French adjectival climbing scale as PD. Its north ridge (graded AD) was first climbed in 1882.

The Dôme de Rochefort (Italian: Dôme de Rochefort) (4,015 m) is a mountain in the Mont Blanc massif in Haute-Savoie, France and of Aosta Valley, Italy.

The Dent du Géant (It.: Dente del Gigante, "giant's tooth") (4,013 m) is a mountain in the Mont Blanc massif in France and Italy. The Dent du Géant remained unclimbed during the golden age of alpinism, and was a much-coveted peak in the 1870s, repelling many parties who attempted it mostly from the Rochefort ridge. In 1880 the strong team of Albert F. Mummery and Alexander Burgener tried to force a passage via the south-west face but were repelled by a band of slabs, causing Mummery to exclaim, 'Absolutely inaccessible by fair means!'The mountain has two summits, 88 feet (27 m) apart and separated by a small col (an 'extremely awkward notch' according to W. W. Graham): Pointe Sella (4,009 m), first ascent via the south-west face by Jean Joseph Maquignaz with son Baptiste Maquignaz and nephew, Daniel Maquignaz on 28 July 1882. Over a period of four days they placed iron stanchions and fixed ropes, enabling the same party to climb Pointe Sella a second time on the following day with clients Alessandro Sella, Alfonso Sella, Corradino Sella and Gaudenzio Sella. Pointe Graham (4,013 m), first ascent by W. W. Graham with guides Auguste Cupelin and Alphonse Payot on 20 August 1882. They used the fixed ropes of "Sella's staircase" to repeat the ascent of Pointe Sella, where Graham noted that one of the Maquignazes had carved the letter 'M' on a rock step. They then lowered themselves 12 metres (39 ft) into the col to climb this higher north-east peak.This ascent marked the end of the so-called silver age of alpinism. On 28 July 1935 the Austrian climbers Herbert Burggasser and Rudi Leitz first ascended the vertical-to-overhanging 160 m-high south face. It was the first climb in the Western Alps systematically aided by the pitons and artificial techniques that were already in use by climbers in the Eastern Alps.During a heat wave in the summer of 2019, a glaciological rarity in the form of a previously unseen lake emerged at the foot of the Dent du Géant, the Aiguilles Marbrées and the Col de Rochefort at an altitude of about 3400 meters, that was considered as evidence for the effects of global warming on the glaciers in the Alps.The following facilities serve the mountain: Torino Hut (3,375 m, CAI, all year) Pointe Helbronner (3,462 m, téléphérique station for Skyway Monte Bianco)

Les Périades (highest point: 3,549 metres (11,644 ft)) is a sharp and heavily-pinnacled mountain ridge, stretching for over 1,500 metres (0.93 mi) in the Mont Blanc massif in Haute-Savoie, France. It runs in a southerly direction from the Col du Tacul to the Col du Mont Mallet. Its highest point is Pointe Cupelin (3,549 metres (11,644 ft))Principal points along the crest of Les Périades, from south to north: Pointe Auguste Cupelin - 3549 m Pointe 3517 m Pointe de la Fenêtre - 3507 m Pointe de Sisyphe - 3460 m Pointe Alfred Simond 3457 m Pointe Nini - 3455 m Pointe Francois Simond - 3493 m Pointe des Périades (or Pointe Paul Perret) - 3503 mLes Périades are divided into three parts by the Brèche Puiseux (or Brèche Supérieure des Périades) and by the Brèche des Périades. A bivouac hut (known as the "Bivouac Paul Chevalier alle Périades") was installed near Pointe de Sisyphe in 1928 at a height of 3,455 metres (11,335 ft). It eventually became the property of the French Alpine Club, and was renovated in 1996. The site collapsed in 2019 during the summer heatwave, which caused the previously frozen ground to become unstable. It was replaced in 2020, following a public fund-raising campaign, and can accommodate three or four people.

The Aiguilles Marbrées (3,535 metres (11,598 ft)), (French pronunciation: ​[eɡɥijmaʁbʁe], literally "marbled needles") is a mountain peak in the Mont Blanc massif, above the Glacier du Géant, with its summits forming part of the frontier between France and Italy. It is situated between the Col de Rochefort and the Col du Géant, and is easily accessed from the Torino Hut at Pointe Helbronner. Seen from the north, the mountain has a triangular appearance. It contains two summits, the northern one being the highest. The lower, southern summit (3,483 metres (11,427 ft)) is separated by a broken rock ridge.: 138 

The Col du Géant (Giant Pass) at 3,356 m (11,010 ft) is the main passage of the Mont Blanc massif between Courmayeur in the Aosta Valley and Chamonix-Mont Blanc in the Arve Valley. On the French side, to the north is the Géant Glacier which overlooks the Mer de Glace.

The Torino Hut (Italian: Rifugio Torino; French: Refuge Turin) is a high mountain refuge in the Alps in northwestern Italy. Located near the border with France, it is about 15 km (10 mi) southwest of Mont Dolent, the tripoint with Switzerland. The refuge is in the Mont Blanc massif above the town of Courmayeur in the Aosta Valley, Italy. It can be most easily accessed from the Italian side by the Skyway Monte Bianco cable car from La Palud in Courmayeur, with a change at the Pavilion du Mont Fréty. It can also be reached from Chamonix via the Aiguille du Midi, either by cable car which crosses the massif, or by a long crossing of the Glacier du Gèant. The refuge lies nearly directly above the 11.6 km (7.2 mi) Mont Blanc Tunnel, which passes deep underground, and connects Courmayer to Chamonix.

Pointe Helbronner (3,462 m (11,358 ft)) is a mountain in the Mont Blanc massif in the Graian Alps on the watershed between France and Italy. The peak, which used to be a mere geodetic reference point, was named after Paul Helbronner, a French polytechnicien, alpinist and geodesist who pioneered cartography of the French Alps. Pointe Helbronner is served on the Italian side by the Skyway Monte Bianco, a cable car from La Palud, a village 2.5 kilometres (1.6 mi) north of the town of Courmayeur in the Aosta Valley. Pointe Helbronner is also served by the Vallee Blanche Aerial Tramway, which crosses from the peak to the nearby peak of Aiguille du Midi in France—a peak-to-peak distance of 5 km (3.1 mi). This, in turn, gives access to the French Téléphérique de l'Aiguille du Midi, the cable car connecting Aiguille du Midi to the French village of Chamonix, Courmayeur's sister "city". The Skyway Monte Bianco station platform on Pointe Helbronner offers a remarkable view over the Aosta Valley and the Piedmont region. The French-Italian border splits this platform. Pointe Helbronner is the starting point of a ski run via the Glacier du Géant and the Mer de Glace to Montenvers and Chamonix. The mountain is the starting point of various routes to other mountains on the Mont Blanc massif, with many mountaineers staying at the nearby Refuge Torino. In June 2015, Italian Prime Minister Matteo Renzi expressed repeated claims on the territory.

The Grand Flambeau (3,559 metres (11,677 ft)) is a mountain peak in the Mont Blanc massif of the Alps. It is situated at the head of the Géant Glacier, approximately 0.5 km (0.31 mi) east of the Aiguille de Toule, between the Col Orientale de Toule and the Col de Saussure. Its summit is one of a number which form part of the mountainous frontier ridge between France and Italy which runs eastwards from Mont Blanc towards the Grandes Jorasses and Mont Dolent. It can be readily accessed from the Torino Hut/Pointe Helbronner, either by its north or southeast ridges, and provides an excellent viewpoint.To the north, a satellite peak - the Petit Flambeau (3,440 metres (11,290 ft)) - rises a small distance above the Géant Glacier.

The Leschaux Hut (French: Refuge de Leschaux) is a refuge in the Mont Blanc massif in the Alps. It is located at 2,431 m on the north side of the Glacier de Leschaux – a tributary of the Mer de Glace. It is owned by the CAF and can accommodate up to 19 people. The hut is used as a base by mountaineers climbing peaks such as Grandes Jorasses, Petites Jorasses and Mont Mallet. It is accessed by going up the Mer de Glace from Montenvers, and then up the Glacier de Leschaux.: 33 : 314  The first refuge was built in 1929. It was enlarged to 30 seats in 1934, but destroyed by an avalanche in 1954. A new hut was built in 1968 and was enlarged in 2003.

The Aiguille de Toule (3,534 metres (11,594 ft)) is a mountain peak in the Mont Blanc massif of the Alps. Its summit is one of a number which form part of the mountainous frontier ridge between France and Italy which descends eastwards from Mont Blanc and continues towards the Grandes Jorasses and Mont Dolent.It is situated at the head of the Géant Glacier. It lies east of the Aiguilles d'Entrèves (from which it is separated by the Col Orientale de Toule) and west of the Grand Flambeau (from which it is separated by the Col Occidental de Toule.) It is sometimes referred to as the Aiguille de Toula.

The Géant Glacier (French: Glacier du Géant) is a large glacier on the French side of the Mont Blanc massif in the Alps. It is the main supplier of ice (via the Vallée Blanche) to the Mer de Glace which flows down towards Montenvers. It gets its name from the nearby Dent du Géant.
