Aareschlucht; a darkland

Haslital is a large valley in the central Alps long from the Grimsel Pass to the Lake of Brienz. The Aare Gorge (Aareschlucht) is a part of the river Aare that carves through a limestone ridge. This gorge is an indirect result of glaciation. Torrential runoff water of melting glaciers eroded a deep, narrow chasm through the limestone barrier around 10,000 years ago, when the Ice Age was ending. The current measurements of gorge is estimated 1400 meters long and up to 200 meters deep. The gorge width varies from 30 meters at its widest to 1 meter at its narrowest.
