Glacier de la Masse, Alpine glacier in Pralognan-la-Vanoise, France.

Glacier de la Masse is a large field of ice in a high alpine valley surrounded by steep rock walls. Its surface displays deep cracks and ice towers formed by the constant motion of its massive body.

Glacier de la Masse lies at 2,711 metres in the Vanoise massif, about 8 km from Modane and 1.2 km west of the Pointe de l'Échelle, which rises to 3,442 metres. The surrounding slopes are classed as alpine grassland and woodland, with only about eight inhabitants per square kilometre in the area.

The glacier lies on the slope below Pointe de l'Échelle, 3,442 m, about 1.2 km to the west, and above the town of Modane, roughly 8.2 km to the southwest. Its ice sits at 2,711 m in a landscape of steep rock and scattered forest, and the surrounding area supports only about eight inhabitants per square kilometre.
