If you leave from the bottom of the valley in Valtellina and enter any
valley of Orobie, you will have to face a narrow and inhospitable
ravine but, once you reach a higher altitude, the landscape opens in a
charming and less steep tableland.
This characteristic morphology
depends on the way the so-called suspended valleys formed: they derive
from the action of lateral glaciers which are less imposing than the
main one which dug out Valtellina.
