description Pulvermaar Overview

Pulvermaar is a water-filled volcanic maar crater located in the Eifel region of Rhineland-Palatinate, Germany. Formed by volcanic explosions during the Pleistocene epoch, it is recognized as one of the deepest natural lakes in the state. The crater is surrounded by a distinct tuff ring, a geological feature formed by the accumulation of ejected volcanic material. Today, the site is part of the Volcanic Eifel nature and geopark, where it is used for ecological research, water sports, and tourism.

Where is Pulvermaar located?

Pulvermaar is in the Vulkaneifel region of Rhineland-Palatinate, Germany, near Gillenfeld. It is a water-filled volcanic maar surrounded by a largely closed tuff rim. [Naturpark Vulkaneifel](https://naturparkvulkaneifel.de/en/eifel/landscape/maars-and-crater-lakes/pulvermaar.html)

How deep is Pulvermaar?

The Naturpark Vulkaneifel describes Pulvermaar as about 74 metres deep, making it the deepest maar in the Eifel region. Other references sometimes give a nearby figure such as 72 metres, so the safest summary is roughly 74 metres. [Naturpark Vulkaneifel](https://naturparkvulkaneifel.de/en/eifel/landscape/maars-and-crater-lakes/pulvermaar.html)

How was Pulvermaar formed?

Pulvermaar formed when volcanic activity caused explosive interaction between rising magma and groundwater during the Pleistocene. The explosion excavated a broad crater that later filled with water, producing a maar rather than a lava-built cone.

What makes Pulvermaar different from an ordinary lake?

Its basin is a volcanic explosion crater, and the surrounding tuff wall records that origin. It also has the largest water surface and greatest depth among the Eifel's maar lakes. [Geopark Vulkaneifel](https://www.geopark-vulkaneifel.de/images/downloads/die-maare-der-vulkaneifel_2021_web_EN.pdf)
