Earth pyramids of Ritten - fragile evidence of the last glacial period.Bolzano is located to the north of Verona, to him about 121 km.on the highway, passing through Via Trento can be reached by train and a slightly longer path along other roads, such as a hook to the west along the shore of Lake Garda can offer a more interesting species.
For most people, the Alps are associated with grandiose views of snow-covered peaks, vysyaschihsya over snow fields and glaciers, but in Northern Italy Alps have a completely different look.There are peaks of the Dolomites, whose strikingly steep cliffs with numerous protrusions pierce the sky like giant rows of teeth.This is one of the best in the Alps routes for climbers: not too high, facing the sun most of the day, no impassable glaciers.Bolpano is located west of the Marmolada (3200 m altitude), the ridge with some of the most magnificent peaks of the region, and to the north-east lies the vast hilly plateau Ritten or Renon.
It is composed of a hard crystalline
However, the most striking part of the landscape is much lower.Next to the charming village of Lengmoos in Fnsterbah valley, partially hidden by trees wooded slopes, are the famous earthen pyramids, Ritten or columns.
Amazing earthen pillars in Renon - the remains of glacial moraines - as if imitate the contours of the surrounding trees.Sami columns represent groups of earth towers that look like passing between the trees tall, slender, cloaked figures - many of them, moreover, "jammed" on the top of a small cobblestone.The causes of this strange geomorphological phenomena associated with the last ice age, when the region was covered by a thick layer of ice.
retreated glacier left behind a moraine - detrital material, captured and brought by a glacier and deposited after the ice has melted - and deposits of boulder clay.Boulder clay contains, of course, and boulders, as the name indicates, but mainly consists of sandy clay.Under the influence of atmospheric phenomena clay quickly begins to blur the rain, unless it does not cover the top boulder or large stone.Around the boulder clay is more washed out, until it is hoisted to the top of the turret.Over time, the top of the clay column is too narrow for the boulder and it rolled off her.When the rain would start to wash out the top of the turret, can bare new boulder and a new turret is formed underneath.
