Earth Pyramids, South Tyrol, Italy/Colours of the Earth

The red earth pyramids rise 30 metres high. They are made of caked morain debris and will stay stable as long as they are protected from weathering by a large cap stone. If the stone falls, erosion will set in and the pillars will gradually turn into spiky pinnacles, then into cones and finally crumble away completely. (aerial view)
