The Großglockner (German: Großglockner [ˈɡroːsˌɡlɔknɐ] ), or just Glockner, is, at 3,798 metres above the Adriatic (12,461 ft), the highest mountain in Austria and highest mountain in the Alps east of the Brenner Pass. It is part of the larger Glockner Group of the Hohe Tauern range, situated along the main ridge of the Central Eastern Alps and the Alpine divide. The Pasterze, Austria's most extended glacier, lies on the Grossglockner's eastern slope.
The characteristic pyramid-shaped peak actually consists of two pinnacles, the Großglockner and the Kleinglockner (3,770 m or 12,370 ft, from German: groß 'big', klein 'small'), separated by the Glocknerscharte col.
