The powder maar is a maar filled with water and is located southeast of Daun in Rhineland-Palatinate . In addition to the Holzmaar, it belongs to the Gillenfeld Maars.

particularities

One in Moor education of the neighboring Strohner Maar contained Tufflage is attributed to the Pulvermaar, this is thus older than the Pulvermaar. Earlier pollen analyzes of the moor formation showed an age of the tufflage - and thus the powder maar - of around 10,050 years. However, recent studies have shown underwater terraces at greater depths as well as ice wedges within the tephra layers, both of which suggest that the maar was formed in the last glacial period 20,000 to 30,000 years ago. Vulcanologists from the Smithsonian Institution place the last eruption of the Strohner and the Pulvermaar between 8600 and 8000 BC. A.

The almost circular maar has steep funnel-shaped walls. The Maarsee lies at an altitude of 411  m above sea level. NHN and with a maximum water depth of 72 m it is the deepest in the Vulkaneifel . With a diameter of around 700 m and a lake area of ​​approx. 38.48  hectares , the lake also has the largest water surface in the Eifel maars, even if the entire volcanic structure of 900 × 950 m is exceeded by many other Eifel maars.

In the winter

After Lake Constance , the pre-Alpine lakes ( Königssee , Walchensee , Starnberger See , Ammersee , Chiemsee , Tegernsee ) and Schaalsee (Mecklenburg-Western Pomerania / Schleswig-Holstein), the Pulvermaar is the deepest natural lake in Germany. It is estimated that the powder maar was originally 200 m deep than it is today. Its ring wall is said to have had a height of 50 m.

The maar is surrounded by forest on the crater wall, through which a hiking trail leads around the lake. There is a bathing establishment on the east bank.
