Sandstone rocks



Nature Reserve Apolena is situated near castle Trosky east of the village Troskovice. Rock towers were separated by erosion after fracturing of the sandstone basin. The eruption of the nearby volcano 17 million years ago, and also falling of  individual blocks of rock on the hillside of Libuň furrow influenced it. Rock massive and standalone rock towers from the softer sandstone are a good habitat for rock nesting birds such as kestrel, eagle owl, and Jackdaw.

The ravine of Měsíční valley is situated in sloping layers of Korycany formation along the Lusatian fault in the foothills of  Kozákov near the village Vesec. The local quarry is still occasionally used. Sandstone layers sloping to the west are exposed here. The thickness of the sandstone layers reaches  up to 7.1 m. The 30 m high canyon walls are closing together and end in the formation called Vrata. Slender rocky pinnacles and caves, some of them of pseudokarst origin, such as Babí pec and Kudrnáčova pec, and others created by human hands accompany the main rocky canyon. A rich paleontological discoveries such as Ichnofossils were made in the area.

Originally horizontal Cretaceous sandstones were erected to almost vertical position by tectonic activity in Tertiary Period. Significant ridge with its length of 1 km is towering above Malá Skála village and it is divided into 20 rock towers, some of which reach heights of up to 80 m. Coarse-grained  and partially conglomerated sandstones are variously siliphicated and ferruginizated along the fault plane. The occurrence of tectonic mirrors, strongly siliphicated tectonic ribs and a dense grid of quartz veins is unique. Suché rock, also called Cantor´s organ, are a popular tourist destination, especially among rock climbers.
