The Rodderberg – a geoscientific object of research and education
Since the beginning of geological research in the 18th century the extinct volcano Rodderberg, located near Bonn, is an important object of science, research and teaching. Numerous studies and publications, historic and recent, attest this. Summarizing volumes respect the Rodderberg volcano, also. Down to the present day biological and geological excursions visit this interesting locaton. It has something special ... more

The British Pioneer of the systematic geology, Sir Charles Lyell (Principles of Geology, 1833), visited the Rodderberg volcano in 1833 and compared it with the Vesuv in Italy. He studied as well the first drilling in the crater of the Rodderberg, which was 60 to 70 feet deep.

The logo of the project symbolises, that the hole of the crater, all around closed over millennia, acted as a trap for sediments and preserved it all inside.
