The earth pyramids of Ritten are a natural monument that is located on the Ritten, a plateau not far from Bolzano in northern Italy. The original name in this area for these earth pyramids is Lahntürme, i.e., landslide towers. 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. https://en.wikipedia.org/wiki/Earth_pyramids_of_Ritten
