Unteraargletscher
The Unteraargletscher, literally "Lower Aare-Glacier", is the larger of the two sources of the Aare river in the Bernese Alps. It emerges from the association of the Finsteraargletscher and the Lauteraargletscher and flows for about to the east down to the Grimselsee near the Grimsel Pass. In total the glacier was long and in area in 1973. Its lower end is almost 400 metres lower than that of the neighbouring Oberaargletscher.
In 18th and 19th centuries, it was one of the first subjects of developing glaciology.
