Großer Stein (Altentreptow, Germany)

3D Model

The “Großer Stein” is an erratic block in the town Altentreptow (Mecklenburgische Seenplatte) in North Germany. The volume of the block is estimated at 166 m³ (ca. 450 t), which means that it is the third largest of the North German erratics. It was transported to this region by the Scandinavian Ice Sheet during the last Pleistocene glaciation of North Germany (Weichselian main glaciation, ca. 25 000 to 15 000 years ago). The erratic is similar to the granites of the type Spinkamåla known from Blekinge in Southeast Sweden. Until the year 2021 the lower part of the erratic was located below the surface, but the block was lifted as part of a media-effective campaign.

This model is part of the project “Geologie grenzenlos”: https://geo.uni-greifswald.de/lehrstuehle/geologie/regionale-geologie-strukturgeologie/mitarbeiter-des-lehrstuhls/erklaerungen-geologie/

The model was created by Moritz Lang and Anna Gehrmann (University of Greifswald, Interreg).
