One of the area's interesting geomorphological features are the numerous block deposits on the summit of the Beigua massif, which have always been attracting the interest of hikers and researchers. In the past, geologists have already described these large block deposits (Issel A.1892; Sacco F. 1934; Conti S. 1940). Several studies ensued, with the purpose of understanding their origin (gravitative, glacial or periglacial) and how they originated and moved.
According to recent studies, the structures and morphologies of several deposits are similar to those of "blockstreams" that are currently forming in periglacial areas.
