the largest maar in the Western Eifel
The basal complex consists of Lower Devonian siltstone, sandstone, greywacke and quartzite (Eckfeld- and Reudelsterz layers) as well as Triassic sandstone (medium mottled sandstone), partly covered by the maar tuffs. Particularities In 1877 German emperor Wilhelm I gifted 12,000 Reichsmark to the people of Meerfeld so they could lower the lake level by 2 m for land reclamation. In 2008 the International Union of Geosciences determined the Meerfeld maar a regional type locality to define the geographical Pleistocene/Holocene limit. The longest drilling core with sediments of the Meerfeld maar is 45 m long, documenting 25,000 years of climatic history.
Open Mar 26, 2020 through Dec 31, 2030 from 00:00–23:45.
