Mont Blanc and Its History
It’s imposing, extremely tall, and admired by all for its beauty. We’re talking about the Mont Blanc massif and a history that’s been in the making for millions of years
In the Valle d’Aosta region of Italy it dominates the Veny and Ferret valleys. In France, in the Savoy region, it encompasses the valley of Chamonix, all the way to the Canton Vallese in Switzerland, near Martigny.
4,808.72 metres is the latest official measurement of Mont Blanc, registered in 2017.
- between 500 to 250 million years ago, during Hercynian orogeny, the crystalline core was formed, which is the base of the current Mont Blanc;
- between 250 and 60 million years ago the mountain was still sunken at a depth of dozens of meters beneath the sea;
- 30 million years ago, during the Tertiary Period, following the push of the African and Asian tectonic plates the mountain chain of the Alps was formed, with Mont Blanc’s emergence from the ocean along with 24 other peaks over 4,000 meters tall.
THE MASSIF AND ITS ROCKS
The Mont Blanc massif is composed of a granitic core around which can be found metamorphic rocks such as gneiss, mica schists and limestone schists.
