Calanchi di Aliano: Erosion and Geology in Basilicata

A detail of the Calanchi di Aliano, remarkable geological formations located in Basilicata. These structures are the result of intense erosion on the clay soils, typical of the region. The Calanchi are formed through a process of pluvial erosion that deeply affects the clay and sandy soils, previously deposited in river and lake environments. The absence of stable vegetation accelerates erosion, since the roots of the plants are not present to consolidate the soil. The steep walls and the sharp forms are distinctive characteristics of the calanchi, highlighting the dynamic interplay between geology and dry climate. This unique landscape not only offers a split on the erosive processes, but is also an integral part of the cultural and natural identity of the Basilicata.
