Géant Glacier

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.

Access

It is possible to take the Vallée Blanche Cable Car which travels right over the Géant Glacier, from the Aiguille du Midi in France, to Pointe Helbronner on the Italian/French border.[1] Experienced skiers also have an "outstanding attraction" in the challenging run from the Aiguille du Midi telepherique station, down the Vallée Blanche and onto the Géant Glacier then, avoiding the Seracs du Géant, merging onto the Mer du Glace to reach the resort of Montenvers[2]

Early studies

In 1862, the physicist and mountaineer John Tyndall gave a series of lectures to the Royal Institution in which he reported on his studies into heat as a form of motion. By placing lines of stakes upon the ice, he made numerous measurements of ice flow from the Géant Glacier and surrounding glaciers into the Mer de Glace.[3] He subsequently published further accounts in his 'Glaciers of the Alps.

gollark: > The relatively small, liberal, pro-business, outspoken government juggles the competing demands of Administration, Education, and Industry. Citizens pay a flat income tax of 8.2%.
gollark: > The Free Land of Anrak is a massive, efficient nation, remarkable for its deadly medical pandemics, keen interest in outer space, and absence of drug laws. The hard-nosed, hard-working, democratic population of 2.677 billion Anrakians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.
gollark: I have Notelia, my main one which also seems to have gone socialist because the game seems to like that for some reason, Anrak, where there is literally no law enforcement (but government-provided education if I remember right), and Doemokria, where I do random testing.
gollark: I mostly just answer the issues occasionally on my three nations.
