Tags: Glacier.
The Unteraar Glacier (Unteraargletscher in German) is the larger of the two sources of the Aar river in the Bernese Alps. It emerges from the association of the Finsteraar Glacier (near the Finsteraarhorn) and the Lauteraar Glacier (near the Lauteraarhorn) and flows for about 6 km (3.7 mi) to the east down to the Grimselsee near the Grimsel Pass. In total the glacier is 12.95 km (8.05 mi) long and 29.48 km2 (11.38 sq mi) in area (1973).
