The Pulvermaar is a water-filled maar that lies southeast of Daun in the German state of Rhineland-Palatinate.

Early pollen analyses of the bogs gave an age for the tuff site – and thus the Pulvermaar – of about 10,050 years.

[1]: 309 [2] Vulcanologists from the Smithsonian Institution estimate the last eruption of the Strohner Maar and Pulvermaar in 8,300 BC.

The maar lake lies at a height of 411 m above sea level (NN) and, with a maximum depth of 72 metres (236 ft), is the deepest in the Volcanic Eifel.

The maar is surrounded by woods on the rim of the crater, through which a footpath runs around the lake.
