The original name in this area for these earth pyramids is Lahntürme, i.e., landslide towers.[1] They originate from glacial moraine rocks. The columns of the pyramids may be more or less elongated, and the higher they are, the thinner they get, ending usually with a stone cover. These earth pyramids are constantly evolving, continuously eroding, and will possibly collapse and make way for new formations.
