Geospot: Lehnskov
Between Ballen and Lehnskov Mølleskov lies a series of cliffs with several different moraine layers from the Saale and Weichsel periods.
Marine and freshwater deposits occur sporadically, possibly dating from the end of the Elster Ice Age and the subsequent Holstein Interglacial.
In the cliff at Mølleskov, a small profile is seen in layered marine clay belonging to the 59.5 million-year-old Æbelø Formation. The irregular layering in the Æbelø Clay may reflect some special climate fluctuations that have astronomical causes in the form of changes in the solar radiation at the time.
The clay is strongly folded and has been incorporated into the Quaternary layers by an ice advance about 18-19,000 years ago.
