Eastern Alps
From Mount Wiki
The Eastern Alps are commonly subdivided according to the different lithology (rock composition) of the more central parts of the Alps and the groups at its northern and southern fringes:
- Northern Limestone Alps (from the Wienerwald to Bregenzerwald), including the Flyschzone; peaks up to 3,000 metres (9,840 ft)
- Central Eastern Alps (Austria, Switzerland); peaks up to 4,050 metres (13,290 ft)
- Southern Limestone Alps
The border between the Central Alps and the Southern Limestone Alps is the Periadriatic Seam. The Northern Limestone Alps are separated from the Central Eastern Alps by the Graywacke Zone.
