Resumen de Alien world of the Alps
You don't need a spaceship to see alien landscapes up close. Just take a hike in the South Tyrol in northern Italy, where fog and the glow of dawn help create an otherworldly spectacle. These strange formations are called Erdpyramiden in German and Piramidi di terra in Italian, which both translate to earth pyramids. Their origins lie in the boulder-studded moraine clay deposited by glaciers during the last ice age. Torrential rain erodes exposed clay, while the rocks protect material directly beneath them. When the conditions are just right, over time the rocks "Rise" out of the landscape.
