Trautzberger Maar Smallest Volcanic Lake in the Eifel. And the Youngest.
It may sound confusing at first, but it's quite simple. Trautzberger Maar in the Wartgesberg nature reserve was drained in the 1960s to create new agricultural land. However, in 2014, efforts began to rehydrate the maar, and it has since become a small lake once again.

The maar has cut into the Bänderschieferfolge, which is a transitional layer between the lower Devonian Siegen and Unterems stages. It comes from the northeast, passing through Büchel and ending here in the Strohn area. The shale sequence is almost entirely overlaid by maar tuffs, which are red-colored here and contain reddish sandstone and shale fragments. They are overlaid by black basalt lapilli tuffs from the Wartgesberg volcanoes and, finally, by ashes from the Sprinker Maar, which various geological exposures in the area confirm. Ice wedge pseudomorphs have also been observed in the maar tuffs. With the different origins of the tuffs, this is evidence that this maar crater must have formed during the last Ice Age.
At the northwest edge of the crater, the elevation measures 420 meters, while at the eastern edge, it is only 392 meters, resulting in a difference of 28 meters. This correlates well with a crater depth of approximately 20 to 25 meters. Trautzberger Maar opens up to the east and drains into the Diefenbach. This drainage was artificially created around 1820/30 to drain the maar for agricultural use. Prior to that, it was used as a fish pond.
Trautzberger Maar is located north of the K26 and north of Trautzberg in a depression. The maar crater formed in a tiny side valley of the small Diefenbach stream, approximately 1.5 kilometers east of Strohn.
