Geology

Short characteristics of the site: The Bohemian Cretaceous Basin. Broader area is represented by slightly tilted tectonic block. Castellated sandstone rocks (so called rock city)form dominating part of the area. Numerous sandstone towers, pillars and mesorelief features and deep canyons consisting of Cretaceous quadersandstones cover the largest of the area. The highest point is made of a dyke of olivinic nephelinite. Ancient and recent landslides (last one from 1926) affected marginal parts of the castellated sandstone massif.
