Felsenmeer Lautertal - sea of rocks

From the "Felsberg" a huge agglomeration of rocks stretches across the hillside down to the valley. Find out more about its hundreds of million years old history at the Felsenmeer Information Center.

The quartz diorites (crystalline rocks) of the Felsenmeer (sea of rocks) were formed about 340 million years ago in the depth of more than 12km. During that time, two ancient continents collided and the ancient Odenwald was situated directly in the collision zone. Due to the collision rock melts have been formed which rised up to the upper Earth crust and cooled by generating huge crystalline rock bodies. The Quartz diorites of the "Felsenmeer" also belong to this ancient collision zone. Due to erosion processes of the overlying rock strata, the former deeply buried rock bodies reached the surface where they were significantly influenced by weathering processes along cracks and fissures. The rocks which got a rounded shape have been exposed during the ice ages (2.5 to 10.000 years before today) and, as a result of frost and thaw processes in combination with soil creeping, they were transported down to the valley. During the 3rd and 4th century the Romans used the "Felsenmeer" with its resistant rocks as quarry. Witness of these former stone masoning activities are more than 300 work piece relics in the upper part of the area like the Giant Column, the Ship or the Pyramid. Comprehensive information and exciting guided tours are offered by the team of the "Felsenmeer" information center. Based on its uniqueness the "Felsenmeer" has been awarded as "Geotope of the year 2002" by the Geo-Naturepark Bergstraße-Odenwald. Information: www.geo-naturpark.de
