  1. THE GLACIER PART 2

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

  3. 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

  4. THE LAKE BORN BETWEEN THE CLOUDS Ghiaccio del Rocciamelone

  5. First phase of development in the 1980

  6. The situation in September 2000

  7. Measurement of the depth of the lake using a sonar

  8. The glacial erosion Strong pressure exercised by the glacier moving and by the friction enhanced by the presence of debris.

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

  10. The lower Susa’s valley

  11. Moraine accumulationJumble of boulder scattered in a matrix of sand and silt

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

  13. Glacier of the Mare (Ortles-Cevedale)

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

  15. Glacial strip (Valley of Funes – Alto Adige)

  16. Sheepbacks (or back of whale) Striped rocks

  17. The sheepbacks are generally rounded on the top and in the side, oriented according to the direction of glacier

  18. The big rocks Erratic rocks The erratic rocks can be transported over long distances by glaciers

  19. Caselette The big rock in the entrance of the village

  20. Pianezza Il “Roc”

  21. Villarbasse

  22. Condove

  23. 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

  24. THE VALLEYS SUSPENDED

  25. The longitudinal profile of a glacial valley

  26. threshold navel Germanasca’s Valley – Torino – I tredici laghi

  27. Rock glaciers characteristic accumulations of large blocks with their lobed shape
