Dent du Géant
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, apart and separated by a small col( an' extremely awkward notch' according to W. W. Graham):
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:
Dent du Bourgo
The Dent du Bourgo( 1,909 m) is a mountain of the Swiss Prealps, located east of Gruyères in the canton of Fribourg.
It lies on the range north of the Vanil Noir, between the valleys of the Sarine and the Motélon.
Aiguille de Rochefort
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.
Aiguilles d'Entrèves
The Aiguilles d' Entrèves is a mountain peak in the Mont Blanc massif of the Alps.
It is situated at the head of the Glacier du Géant, and its rocky summit ridge forms part of the frontier between France and Italy.
It lies east of the Tour Ronde, between the Col d'Entrèves and the Col Occidental de Toule.
It has a steep, sound face of red granite and can be readily accessed from the Torino Hut/ Pointe Helbronner.
Dent du Vélan
The Dent du Vélan is a peak in the Chablais Alps, located north of the Cornettes de Bise.
At above sea level, its summit straddles the border between Switzerland and France.
The Dent du Vélan is the westernmost summit rising above in Switzerland.
Aiguilles Marbrées
The Aiguilles Marbrées 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 is separated by a broken rock ridge.
Tête du Géant
Tête du Géant is a mountain in the Chablais Alps on the Swiss- French border.
Dent du Chat

Dent du Salantin
The Dent du Salantin is a mountain of the Chablais Alps, overlooking the Rhone valley between Evionnaz and Vernayaz, in the canton of Valais.
It lies in the massif of the Dents du Midi, east of Lac de Salanfe.
Monte Matto
Monte Matto is a 3,097- meter- high( 10,161 ft) mountain in Piedmont, in the province of Cuneo, Italy.
It is part of the Maritime Alps, dividing the Meris valley from the Gesso della Valletta valley.
The mountain peak, consisting of a ridge of four aligned summits, can be seen from most of the plains near Cuneo.
The ridge is composed of two different rock formations, one made up of granitoid gneiss, the other of mixed gneiss and different kinds of migmatite.
The four peaks are( from east to west) cima Est( 3,088 m), cima Centrale( 3,097 m), cima Bobba( 3,079 m) and cima Verani( 3,020 m).
The mountain is clearly visible from the plains around Cuneo as a triangular shape with a peculiar tiny" tooth"( which corresponds to cima Centrale, i.e. the central summit).
It is part of the natural park" Parco Naturale delle Alpi Marittime".
The fauna includes marmot, chamois and, at higher altitudes, the alpine ibex.
