Gelenberger Drees Carbon Dioxide Spring

In the Eifel volcanic region, there are many mineral and carbonic acid springs, also called Drees. The Gelenberger Drees is one of them and you can watch the water bubbling through the rising volcanic carbon dioxide.

A carbon dioxide source (mofette) in the forest near Gelenberg, accessible via a beautiful forest path, for example on the themed circular trail "What was really true".Many years ago, it was believed that the release of carbon dioxide was a sign of extinct volcanism. But this is not the case: the molten rock in the earth's interior (magma) contains not only mineral components but also gases such as carbon dioxide, water vapor, sulfur dioxide, fluorine and chlorine. Depending on how warm it is and how much pressure is created, they escape through cracks in the earth's crust. The carbon dioxide source in the Gelenberg forest is a mofette. The volcanic carbon dioxide rises from a depression filled with rainwater and causes the water surface to constantly erupt. The unique thing about it is that the mineral water deposits form the natural carbon dioxide of the Volcanic Eifel, which is the basis of the local sparkling water industry.
