The Dohlenstein is a huge landslide in the Saale valley, which is active since at least 1740. The largest landslides have even changed the course of the Saale river. Here, rocks of the Muschelkalk overlie Buntsandstein units (Triassic). The uppermost layers of the Buntsandstein consist of clays. There, water accumulates in the rock and a sliding surface is formed. On this sliding surface the overlying rocks move towards the valley and form a large debris cone. The landslide cliff can be seen from afar as a bright white, vertical rock face.
We present a 3D model of the Dohlensteins as part of the DGGV project 30Geotope³. More information, videos, and 3D models can found on the project website: digitalgeology.de.
