The Eastern Alps strike south of the Flysch Zone and occupy the largest area in the German Alps. In Germany, the Eastern Alps are, for the most part, Mesozoic mostly Triassic carbonate rocks. This carbonate rock association, whose outcrop (including the Austrian parts) runs in a 35 to 50-kilometre-wide strip from Vorarlberg as far as the Vienna Basin, is called the Northern Limestone Alps. In contrast to the Helvetic Domain and the Flysch Zone that still mostly have a low mountain character (German: ) although they are morphologically clearly set apart from the Alpine foreland, the Northern Limestone Alps form high mountains (German: ) of well over 2,000 metres above sea level. Of the high mountains of Germany, the highest is Zugspitze, with a height of 2,962 metres, more than a thousand metres higher than Feldberg in the Black Forest, Germany's highest mountain outside the Alps.
