Erratics are relics of the ice ages. In the Quaternary period (around 1 million years ago) they reached the Lower Rhine Bay when glaciers and their meltwater released them from the subsoil. They drifted on ice floes and were finally deposited in the Rhenish lignite mining area between Cologne, Düsseldorf and Aachen. As the overburden was removed, the blocks, which weighed several tons, were exposed in the open-cast lignite mine. This example was transported here on the occasion of the annual pilgrimage of the St. Matthias Brotherhood of Jüchen to the grave of St. Mattihas. This drift stone comes from the Garzweiler open-cast mine and was exposed in 2001.

The CO2 springs are classified as simple acid springs. The gas, carbonic acid dissolved in water, rises through the cracks in the fault line and partially dissolves in the groundwater at a shallow depth. The now slightly acidic water dissolves mineral compounds from the rock it flows through, which settle on the earth's surface as spring sediment. The mineral springs around Heckenmünster have a high iron content, which results from the fact that in the subsurface of the spring areas, at a depth of approximately 10-20 m, there is a red iron horizon through which the springs flow. The springs generally produce extremely low water flow, between 1 and 3 liters per minute. The Viktoria spring in Heckenmünster was used commercially around the turn of the century; between 1880 and 1900, approximately 50,000 bottles of mineral water were bottled annually. In the immediate vicinity of the spring, you can still find many pieces of glass and broken bottles that were broken or discarded at the time. Source: Eifel.info

Unfortunately no drinking water for the bottle. But in an idyllic location.

Can smell a bit :-)

Nice place to stay

Great place to stay with a refuge
