GEOMORFOLOGIA

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

Strong pressure exercised by the glacier moving and by the friction enhanced by the presence of debris.

U valleys Ample funds and often stepped, flanked by steep scarps

The lower Susa’s valley

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)

Glacial strip (Valley of Funes – Alto Adige)

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 rocks

The erratic rocks can be transported over long distances by glaciers

Caselette The big rock in the entrance of the village

Pianezza Il “Roc”

Villarbasse

Condove

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
