When the moler (a type of clay) was formed app. 55 million years ago, the area was quite different than we know it today. The island Mors did not exist. In stead there was a 200 m deep ocean. The moler was shaped by microscopic alga, also called diatoméer, which grew at sea level. When huge amounts of these alga constantly sank to the bottom, the alga’s digestion created a lack of oxygen on the sea bed for thousands of years. Therefore it is rare to find fossils from the sea bed. However, the other animals such as fish, birds, reptiles and insects were preserved in an impressive quality, because the lack of oxygen in a way conserves the dead animals. Now and then wood and leaves drifted from the forrest areas to the area, which today is Mors. During some periods, impressive crystals were formed in the moler, including the Lynghøj Crystal, which is the largest crystal ever found in Denmark.
The scenery on Northern Mors is characterized by the many impressive moler slopes that lie side by side from Sundby on the westcoast to Ejerslev on the eastcoast of the island. The moler slopes only exist in the western part of the Limfjord and nowhere else in the World. More than half of the moler slopes can be found on Mors, and each of them are very different in shape and size. The unique moler slope Hanklit is 61 m high and nominated for the UNESCO World Heritage List. The beautiful layers was formed during the ice ages and the many dark streaks of volcanic ashes give a special kontrast to the brighter moler. There are parking facilities close
to the slope and you can always go to the top of Hanklit and enjoy the amazing view. A walk along the beach at the bottom of the slope is also recommendable. The moler slope Knudeklint on the island Fur is, along with Hanklint, also a candidate for the UNESCO World Heritage List and both slopes are expected to be accepted within a few years.
Mors has a 100 year long tradition with extraction of moler. In the beginning the moler was extracted by hand and scooped into horsedrawn trailers. The moler was used to produce isolating bricks and this production continued until the late 1970’s, when a new product took over; granulated moler. Today, two active moler pits
still deliver raw material to the modern factory at Skarrehage. When not used for extraction, everyone can visit the active moler pits and search for fossils.
If you want to know more about the geology of moler and its use as raw material, the Moler Museum is definitely worth a visit. The museum has an impressive collection of moler fossils. All the exhibited items are from the local area, with main focus on the geology of the moler. Each year the museum has a special exhibition with changing themes. In 2015 the special exhibition is called “From chalk to iPad” and contains many nice fossils from the Chalk Ages. During the summer season the museum offers guided fossil hunts in the museum’s own moler pit, only 50 m from the museum.
