Young Curly Brunette Girl Shows Off In The Alpine Mountains Above The Valley Tarn And A Small Village

The geologic subdivision is different and makes no difference between the Western and Eastern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the center and, south of the Periadriatic Seam, the Southern Alpine system and parts of the Dinarides. Geographically, the Jura Mountains do not belong to the Alps; geologically, however, they do.
Main chain
The secondary chain of the Alps follows the watershed from the Mediterranean Sea to the Wienerwald, passing over many of the highest and most famous peaks in the Alps. From the Colle di Cadibona to Col de Tende it runs westwards, before turning to the northwest and then, near the Colle della Maddalena, to the north. Upon reaching the Swiss border, the line of the main chain heads approximately east-northeast, a heading it follows until its end near Vienna.
