What is "aargletschers"

The Aargletschers, literally "Aare-Glaciers", are a system of glaciers located at the sources of the Aare river in the Bernese Alps, Switzerland. The original name has no plural-"s", as in German the plural of "gletscher" is only marked by changes of the article. The Aargletschers are constituted by two distinct partial glacier systems:

• Unteraargletscher: composed by the converging Lauteraargletscher and Finsteraargletscher, between the Lauteraarhorn, Finsteraarhorn and Grimselsee .
• Oberaargletscher: between Oberaarhorn and Oberaarsee .

Grimselsee and Oberaarsee are recent reserve lakes. The "…-Aar-Horns" are summits of more than 3600 metres above sea level, two of them even above 4000 metres.
