Earth pyramids at Renon
The Renon earth pyramids are the highest and best formed in Europe. They are a phenomenon of erosion, formed from glacial moraines. When dry, this moraine clay is as hard as stone, but when dampened it forms a porridge-like substance and slips downhill. This builds up steep cliffs, which form the pyramids when large stones contained in the moraine protect the mud below. The protected areas remain hard and the rest slips into the valley. With each rain a little more is eroded. When the protecting stone falls, however, the unprotected pyramid rapidly disappears.From: http://www.suedtirol-it.com/renon-en/earth-pyramids.htm
