On the steep bank to the lake Zansen is a huge erratic boulder, which the migrating ice brought from Scandinavia. Of course, myths entwine around this special stone, precisely because of its mysterious scratch marks.
If you hike along the nature trail over the Hullerbusch, which is bordered by the two lakes Schmaler Luzin and Zansen, you can discover the Devil's Stone in addition to moors and stately beeches. But what can be so special about a stone? First of all, the granite block is really very large: over two meters wide and more than one meter high. It lies almost unburied in the landscape. And then there are the scratch marks on it. Legend has it that the devil threw the boulder over the Zansen after a miller who was supposed to have prescribed his soul to it. The twenty or so grooves carved deep into the stone are said to have come from the devil's hands. Nowadays, it is more likely that the enormous forces of the advancing glaciers have carved the stone in this way. Because of the well-preserved glacial scars, the stone is significant for science and thus a natural monument. Normally, rocks of this size used to be put to economic use, but this was impossible with this stone: thanks to its special location - directly on the steep bank to the lake - any crevasses would have rolled directly into the lake and thus been lost. So today it still lies majestically in the forest, waiting to be discovered and marveled at by you.
