Holzmaar, Dürres Maar, Hetsche Määrchen


Share content:

The Holzmaar is the best reserached maar worldwide. It is about 40.000 to 70.000 years old and now about 20 m deep. Starting in the 1980s, the University of Trier, and later on German Research Center for Geosciences in Potsdam until today, numerous drilling cores were taken form the Holzmaar and analysed. New research methods have been testet and optimised here.

During the 16th century tha lake was dammed toward the south to supply Gillenfeld saw mill in the forest about 2 km to the south.

Dürres Maar is about 4.000 years old and has a bock thickness of noy 12 meters. Former is was 9 meters deep. The dürres maar area was made a nature conservancy in 1979 along with the Holzmaar. It represents the second oldest volcanic eruption site in the Holzmaar group and is now filled with a transitional moor.

Hetsche Maar is the oldest maar in the Eifel and it is only 5 meters deep. It is about 200 meters north west of the Dürren Maar and it is depply embedded in the surrounding fields, but visible form the street between Brockscheid and Gillenfeld. It is the smallest maar in the Eifel and created by one to two eruptions. By the way, Hetsche is the Gillenfeld colloquialism for the common toad, a reference to a local inhabitant.

Schalkenmehrener Maar

Especially if you visit the GesundLand Vulkaneifel in summer, a detour to the Schalkenmehren Maar is a must. Located directly at the village of the same name and opposite the Weinfelder Maar, the Schalkenmehrener Maar is one of the three Dauner Maars and offers a wonderful backdrop for an extended walk or an extensive hike. If you look closely, you can see that the Schalkenmehren Maar was once a double maar, formed by volcanic activity around 20,000 to 30,000 years ago. But the tuffs of the western maar filled up the eastern maar funnel, so that nothing can be seen of the second maar today, except for the fen vegetation that has spread in this area. Take a little discovery tour and observe numerous animal and plant species along the way!
