Tips

Bernd 🌲🦌🍄🥾

July 27, 2022

The boulders that protrude here and there from the grass and appear lost and strange in the marshy surroundings raise the question of their origin. The colors of the stones vary from gray-blue to black and are often crossed by white veins. They come from the first geological era of the Cambrian and are marine deposits from 500 million years ago that have undergone a transformation process over the course of Earth's history and finally form today's very hard so-called Vennwacke. They came to the surface during the ice ages. At that time, the ground of the High Fens was permanently frozen to a depth of 10m and only in summer did the ground on the surface thaw. However, as soon as the condensation water in the upper clay layers reached a certain degree of saturation, flowing earth developed even at low slopes, which also carried away the blasted quartzite blocks from the existing rock formations. Due to the frequent alternating periods of frost and thaw, more and more Vennwackes accumulated in the upper layers of the earth and finally emerged to the surface of the earth. Depending on their size and shape, the Vennwacken were carried by the flowing earth to different distances. While rubble-like accumulations of smaller Vennwackes reached the valleys, the larger ones remained on the ridges of the High Fens.

On this section of the path you can see these large boulders on both sides again and again. These quartzite sandstone blocks were formed 500 million years ago, exposed by erosion and displaced by glacial soil movement. One of the most well-known Vennwacken is Kaiser Karl's bedstead near Mutzenich.
