Aar glacier

from Wikipedia, the free encyclopedia

The Aargletscher are a group of glaciers in the eastern Bernese Alps on the Finsteraarhorn .

There are four huge ice streams that descend from the firn hollows of the Finsteraarhorn group into the background of the Haslital ; first of all the Oberaar Glacier , whose outflow is the Aare , which after a short run takes up the outflow from the Unteraar Glacier . The latter arises from the union of two higher-lying ice streams that descend from the high valleys on the Schreckhorn and are separated below by the rocky ridge of the Lauteraarhorn , namely the Lauteraar glacier and the Finsteraar glacier , which the latter passes at the foot of the Finsteraarhorn. The Aar glaciers have gained increased interest through the scientific studies of Franz Joseph Hugi (1827) and Louis Agassiz , Édouard Desor , Carl Vogt and Hercule Nicolet (1840–53). The researchers were particularly interested in the flow velocity of glaciers. The hut built by Josef Hugi on the Aar glacier, which served as a research station, changed its location by 100 m from 1827 to 1830, by 724 m by 1836 and by 1428 m by 1842.

During the last glacial periods, the Aar glaciers extended significantly further north and united in the Central Plateau with the Rhone Glacier in the southwest and the Rhine Glacier in the northeast.
