Hiking block
A wandering block is a boulder that drifts downward faster than the surrounding material. Typical are the bulge that appears in front of it and the furrow behind it that points up the slope. The hiking block itself consists of weather-resistant rock. The propulsion is created by a moisture reservoir behind the block that forms in spring and pushes it down the slope when it is frosty.
Hiking blocks are common. You kick u. a. in Scandinavia, North West England and the Alps. But they can even be found in northern Germany. For example, there is a group of ten hiking blocks on the eastern edge of the Harburg Mountains that are designated as natural monuments .
