Geology

Short characteristics of the site: Rock city (castellated sandstones). Tectonically deliminated block of Cretaceous sandstones. Intensive morphological differentiation due to a selective weathering. Many interesting relief phenomena. Also pseudokarst features as caverns. Geomorphologically and sedimentologically significant locality.The area has the form of a cuesta looming over the Jizera river valley. It is built up by quartzose sandstones of Turonian-Coniacian age. The sandstone bodies show a complex system of diagonal bedding.
