The glacier Basei viewed from the north, almost completely devoid of snow

We live in a hot natural phase, but in particular the human activities have helped to increase this

phenomenon.

The rate of melting of glaciers has tripled since 1970.

In 2030, the glaciers could be just a memory

THE LAKE BORN BETWEEN THE CLOUDS

Ghiaccio del Rocciamelone

First phase of development in the 1980

The situation in September 2000

Measurement of the depth of the lake using a sonar

The glacial erosion

Strong pressure exercised by the glacier moving and by the friction

enhanced by the presence of debris.

Ample funds and often stepped, flanked by steep scarps

U valleys

The lower Susa’s valley

Moraine accumulation Jumble of boulder scattered in a matrix of sand and silt

Lateral moraine

The lateral moraine that blocks the pond indicates the greater level reached by the glacier

Glacier of the Mare (Ortles-Cevedale)

The amphitheatre of the Lake of Miage (Monte Bianco) is composed of twenty concentric moraines (pile of rock debris)

Sheepbacks (or back of whale)

Striped rocks

The sheepbacks are generally rounded on the top and in the side, oriented according to the

direction of glacier

The big rocks

Erratic rocksThe erratic rocks can be transported over long distances

by glaciers

The rock of Castellazzo

The block rocky region Castellazzo is a typical example of a boulder, fell for landslide on the

surface of a glacier and transported in the valley
