Geology
Short characteristics of the site:
Bohemian Cretaceous Basin. System of water springs in the area of the Hrubá Skála castellated sandstone rocks. These stratal springs are bound to the boudary of claystones and sandstone layers of the Teplice Formation. This spring field feeds water resources of traditional spa area. Position of springs was partly affected by landslides and so these spills occur along a front of landslide bodies. This area is extremely important from the hydrogeological and geomorphological viewpoints. This locality is situated in the Geopark and Protected Landscape Area Český ráj - the Bohemian Paradise.
