Bohemian Massif

The Bohemian Massif; Czech: Česká vysočina or Český masiv; is in the geology of Central Europe a large massif stretching over central Czech Republic, eastern Germany, southern Poland and northern Austria. It is surrounded by four ranges: the Ore Mountains (Krušné hory, or Erzgebirge) in the northwest, the Sudetes (for example Krkonoše, Hrubý Jeseník) in the northeast, the Bohemian-Moravian Highlands (Českomoravská vrchovina) in the southeast, and the Bohemian Forest (Šumava) in the southwest. The massif encompasses a number of mittelgebirges and consists of crystalline rocks, which are older than the Permian (more than 300 million years old) and therefore deformed during the Variscan Orogeny.

The landscapes in the Bohemian Massif are mostly dominated by rolling hills. North of the river Danube the topography is characterized by gentle valleys and broad, flat ridges and hilltops. The highest peaks on the Czech-Austrian borderline are Plechý-Plöckenstein (1,338 m) and Sternstein (1,125 m). The bedrock of acid gneiss and granite is weathered to brown soil (cambisols). In flat areas and valleys the groundwater had more influence on soil formation; in such places gley soils may be found too.
