In the diversified landscape of the Czech Republic, dozens of irregularly dispersed karst areas can be found. Some carbonate bodies have become bared on the Earth’s surface during almost their whole life-spam and have been almost continuously influenced by karst processes.
From a point of view of geology, other have been developing themselves in a more complicated way, e.g. some isolated karst areasin the Western Carpathians Mts., forming small flasers (lenticular structures) and islets. In a karst in the Kamenice River Basin and in the Železný Brod region, there are the only show caves in North Bohemia, the Bozkov Dolomite Caves. They were discovered only in 1944 and since 1999 they have been a National Nature Monument. The underground system not only harbours the largest lake with a static water surface in the Czech Republic, covering 14 x 24 meters, but they at the same time are the country’s longest cave formed in dolomites. In the cave the microclimate is studied in detail: since 2002, natural radiation has been experimentally monitored in co-operation with the Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University Prague. The caves are open to the public all the year round and they are among the most visited underground systems in the Czech Republic. In 2012, they drew more than 60,000 domestic and foreign visitors.
