The Saarschleife near Mettlach (Saarland)

The Saarschleife near Mettlach represents a large river bend. The beautiful landscape can be best seen from the viewpoint “Cloef”. The river Saar formed about 23 million years ago when the meandering river bed started to cut into the bedrock until it reached the older and harder rocks after a few million years of erosion. Accompanied by regional uplift, the Saar cut further into the basement and harder rocks. Fault systems in the underground played an important role in influencing the flow direction of the Saar and the Saarschleife. In summary, the Saarschleife formed by an interaction of surface and subsurface processes. … Continue readingThe Saarschleife near Mettlach (Saarland)

Rügen Island, chalk coast (Mecklenburg-Western Pomerania)

The famous white chalk coast on the Island of Rügen consists of limestone marls from the Cretaceous period. They were formed around 70 million years ago in a cool shallow sea and consist for the most part of microscopic calcite platelets that surrounded unicellular algae (coccoliths). During the last glaciation period, the Cretaceous limestones and the glacial sediments deposited on top of them were pushed and compressed by the moving glaciers and stacked into a sequence of imbrication thrusts. … Continue readingRügen Island, chalk coast (Mecklenburg-Western Pomerania)

The Dohlenstein

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 mudstones. 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. … Continue readingThe Dohlenstein

Devil’s Table (Rhineland-Palatinate)

The Devil’s Table is made of sandstone. The devil is said to have set up the table, but of course that is not true. In fact, the rock of the Devil’s Table formed 250 million years ago in a desert. And the shape was created by wind and rain working the rock. In the process, soft rock layers weathered more easily than hard, solid rock layers. That’s why a kind of table with a large tabletop was formed from the more massive, resistant sandstone layers. There are still many such rocks in the Palatinate Forest. A visit is worthwhile. … Continue readingDevil’s Table (Rhineland-Palatinate)
