The modern state of Austria is considered to have three geographic zones. The biggest consists of the Alps, which covers 62.8% of the country's landmass. In the north, across the Danube, is the Austrian (southern) portion of the Bohemian Massif, called the Böhmerwald or Bohemian Forest, a relatively lower mountain range of granite that makes up another 10% of the Austrian land area. The remaining parts of the country are the Pannonian lowlands along the border with Hungary (11.3%) and the Vienna Basin (4.4%).
