Bossons Glacier

The Bossons Glacier is one of the larger glaciers of the Mont Blanc massif of the Alps, found in the Chamonix valley of Haute-Savoie département, south-eastern France. It is fed from icefields lying on the northern side of Mont Blanc, and descends down close to the Aiguille du Midi and ends on the southern side of the Arve valley, close to the town of Chamonix.

It has the largest altitudinal drop of all the alpine glaciers in Europe, and formerly extended much further down the valley than it does today.

It is now approximately 7.5 km long, with a surface area of approximately 10 km2.
