Dent du Géant

The Aiguille de Rochefort (4,001 m) is a mountain in the Mont Blanc massif in France and Italy. The peak lies on the Rochefort arête between the Dent du Géant and the Grandes Jorasses and is usually climbed during a traverse of the ridge.The first ascent of the peak was by James Eccles and guides Alphonse and Michel Payot on 14 August 1873.

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 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 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.

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 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 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.

The Mont Blanc Tunnel is a highway tunnel between France and Italy, under the Mont Blanc mountain in the Alps. It links Chamonix, Haute-Savoie, France with Courmayeur, Aosta Valley, Italy, via the French Route Nationale 205 and the Italian Traforo T1 (forming the European route E25), in particular the motorways serving Geneva (A40 of France) and Turin (A5 of Italy). The passageway is one of the major trans-Alpine transport routes, particularly for Italy, which relies on this tunnel for transporting as much as one-third of its freight to northern Europe. It reduces the route from France to Turin by 50 kilometres (30 miles) and to Milan by 100 km (60 mi). Northeast of Mont Blanc's summit, the tunnel is about 15 km (10 mi) southwest of the tripoint with Switzerland, near Mont Dolent. The agreement between France and Italy on building a tunnel was signed in 1949. Two operating companies were founded, each responsible for one half of the tunnel: the French Autoroutes et tunnel du Mont-Blanc (ATMB), founded on 30 April 1958, and the Italian Società italiana per azioni per il Traforo del Monte Bianco (SITMB), founded on 1 September 1957. Drilling began in 1959 and was completed in 1962; the tunnel was opened to traffic on 19 July 1965. The tunnel is 11.611 km (7.215 mi) in length, 8.6 m (28 ft) in width, and 4.35 m (14.3 ft) in height. The passageway is not horizontal, but in a slightly inverted "V", which assists ventilation. The tunnel consists of a single gallery with a two-lane dual direction road. At the time of its construction, it was three times longer than any existing highway tunnel.The tunnel passes almost exactly under the summit of the Aiguille du Midi. At this spot, it lies 2,480 metres (8,140 ft) beneath the surface, making it the world's second deepest operational tunnel after the Gotthard Base Tunnel. The Mont Blanc Tunnel was originally managed by the two building companies. Following a fire in 1999 in which 39 people died, which showed how lack of coordination could hamper the safety of the tunnel, all the operations are managed by a single entity: MBT-EEIG, controlled by both ATMB and SITMB together, through a 50–50 shares distribution.An alternative route for road traffic between France to Italy is the Fréjus Road Tunnel. Road traffic grew steadily until 1994, even with the opening of the Fréjus tunnel. Since then, the combined traffic volume of the former has remained roughly constant.
