Terminal moraine near Grünhübl
The terminal moraine at Grünhübl is the worm-age terminal moraine of the Mur glacier .
overview
The climax of the last glacial period was around 20,000 BC. BC and the Alps were glaciated over a large area. Large parts of the ice flowed south over the Neumarkter Sattel and Perchauer Sattel , so that in the Murtal only the tongue of a side glacier extended to just before Judenburg. The Aichfeld was ice-free east of Grünhübl, the peaks surrounding the Aichfeld only showed local glaciations.
Terminal moraine
The terminal moraine of Grünhübl just west of Judenburg thus marks the maximum extent of the Mur glacier from the Würm period. It is about 80 m thick and forms a clear wall above today's Mur. The terminal moraine consists of coarse, partly scratched, crystalline blocks that are backfilled with smaller, sandy bedrock, including lime. The moraine is completely unstratified.
