The Mer de Glace (Sea of Ice) is a glacier located on the northern slopes of the Mont Blanc massif, in the Alps. At 7 kilometres ( mi) long and 200 metres (660 ft) deep, it is the longest glacier in originates at an elevation of 2,400 metres (7,900 ft) where it is fed by the confluence of Glacier du Géant, Glacier de Lechaud, and Cascade du Talèfre, north of Mont Tacul, and descends to 1,400 metres (4,600 ft). It flows north-north-west between Aiguille du Moine on the east and Trélaporte on the west. Le Grand Dru lies to the north east. It was once easily visible from Chamonix, but has been shrinking and is now barely visible from below.[2] It lies in the Chamonix valley, it was the first place in the valley to have a ready-made tourist attraction. The Mer de Glace, like all glaciers, it is constantly renewed under the effect of two phenomena: accumulation, notably due to snowfall and ablation, essentially due to melting. The Mer de Glace flows permanently under the effect of its own weight, causing crevasses, seracs or pockets of water to form, depending on the type of ground. The glacier's speed, although not perceptible to the naked eye, is considerable. From more than 120 metres (390 ft) a year in its upper part, the Mer de Glace moves about 90 metres (300 ft) per year in the region of Montenvers, which is about one centimeter per hour.[citation needed] As soon as the tensions intensify, the glacier is deformed and crevasses appear. These are notably transversal. When there is intense crevasse activity, the breaking-up of the glacier by the crevasses forms blocks of seracs. The unidentified objects, of variable depth, depending on their positioning, may reach fifty metres. They always form in the same place because of the shape of the glacial valley in which the glacier flows. Disappearing downstream, they are renewed upstream. read more :
