During the various ice ages of the Quaternary Period, the Turracher Höhe was glaciated. In the Würm glaciation, there were partial currents of the Mura glacier, which flowed out of the feeding area of the Niederen Tauern to the south. About 20,000 years ago, a strong warming within 1,000 to 1,500 years made the glacial net melt off. As a rare relic of the Würm ice age, there is a glacial mill west of Turracher Lake. Further effects of the glaciation can be observed in the shape of the terrain, as well as in many individual places of the Turracher Höhe. The rounded off mountain tops with tub-like depressions between them (cirques) are the results of the tectonic movements as well as the glaciation. One example of that is the Hohe Kor. There is also a further result of ice age glacial activity there, a moraine embankment.
