Lauteraarhorn
'Loud Aar horn' or 'clear Aar horn' — lauter in older Swiss-German can mean either 'loud / noisy' or 'pure / clear'; the Aar river is named here in its Lauteraar form (the upper, southern branch, paired with the Finsteraar to the north).
Remote rock summit linked to the Schreckhorn by a long ridge, between the Lower Grindelwald and Unteraar glaciers. One of the most isolated 4000ers in the Alps.
Climbed on 8 August 1842 by a large party from the Aar-glacier scientific expedition of Louis Agassiz, the great pioneer of glaciology. Agassiz himself stayed at the Hotel des Neuchâtelois — the rough stone shelter the team had built on a moraine in the middle of the Unteraar glacier — while Desor, Girard, Dollfus-Ausset and four Oberland guides made the climb. For decades the Lauteraarhorn was confused with the higher Schreckhorn (climbed only in 1861 by Leslie Stephen), and an 1828 claim by Franz Joseph Hugi to have climbed the 'Schreckhorn' is now believed to have been an ascent of a sub-summit of the Lauteraarhorn instead.
