Braunauer Bergland
Coordinates: 50 ° 35 ' N , 16 ° 20' E
The Braunauer Bergland ( Broumovská vrchovina in Czech ) is a geomorphological unit in the northeast of the Czech Republic . It occupies an area of 535 km² . The average altitude is 527 meters. The highest mountain is the Královecký Špičák at 880.6 meters above sea level. NN , followed by Ruprechtický Špičák (Ruppersdorfer Spitzberg) with 880.5 meters.
The Braunauer Bergland is part of the Inner Sudetian Depression ( vnitrosudetská pánev ). The part located in the Czech Republic consists of sedimentary and volcanic rocks from the Carboniferous and Permian ages in the form of rhyolites , melaphyrenes , pyroclastic rocks and ignimbritic sequences up to 700 meters thick, as well as sediments with considerable surface area from the former shallow seas of the Cretaceous and on a small scale strip-like deposits from the Triassic . There are isolated ice-age pebbles .
The Braunauer Bergland is geographically divided into several small regions:
- The Halbstadt Bergland (Meziměstská vrchovina) extends to the border with Poland and is made from Blueberry Mountain (Czech Javoří Mountains , Polish Góry Search , on the Czech side with the highest mountain Ruprechtický špičák (880 meters)) and the Broumov boiler ( Broumovská kotlina ) with the lowest point of 350 meters above sea level. NN on the river stones (Stěnava) near the village Otovice . The Heidelgebirge is made up of volcanic rocks such as rhyolite ignimbrites and rhyolite tuffs. On its southern slopes silt rocks and plans . In the Braunau Basin there are paleozoic breccias , conglomerates and sandstones .
- The Politzer Bergland ( POLIČKA vrchovina ) is divided into the Politzer fold mountains (POLIČKA stupňovina) with its most important region, the Falk Mountains , ( Broumovské stěny ), and the Table Mountains ( the Table Mountains ), most of which is located in Poland. The highest mountain is the Szczeliniec Wielki ( large hay barn with 919 meters). The Politzer Basin ( Polická pánev ) consists of elongated, jagged table surfaces in which u. a. the famous rock labyrinths Ostaš and Hvězdy are located. The Politzer Basin is also an important reservoir of water, with the water being accumulated in the sandstone layers.
- The Schatzlar mountainous region ( Žacléřská vrchovina ) consists largely of volcanic rocks (rhyolites), silt rocks, conglomerates and permocarbonic arkoses . It shares in the Radowenzer mountains ( Radvanická vrchovina ) and the Habicht mountains ( Jestřebí ), whose highest point on the 739-meter Žaltman ( Hexenstein forms).
The natural beauties include the rock towns, formed by sandstones of the Cenoman , Turon and Coniacium with strongly structured terrain. The most famous rock towns are the Adersbach-Weckelsdorfer Felsenstadt and in the Falkengebirge. Forests cover about 35 percent of the area. At high altitudes, they are badly damaged by emissions from the power plants.
Almost the entire area - with the exception of a large part of the Radvanická vrchovina - is part of the Broumovsko nature reserve .
