Earthly pyramids of South Tyrol, Italy
This unusual buildings began to take shape from the floor of Moranski clay that fell behind after the last ice age when the glaciers melted. The dry soil is hard as stone, but as soon as the rain turns into a soft, muddy mass start skating and forms a large steep slopes of 10 to 15 meters. When the rainy season starts, these slopes are eroding. But when the mud has rocks, clay soil beneath these rocks remains protected from rain. Thus, while the surrounding material continuously cope with rain, the protected poles rise up out of the ground and ground to form a magnificent pyramids. It can take hundreds to thousands of years to form the pyramid.
