The Cimoliana Valley, to the north of the village of Cimolais, is a long valley that leads deep into the most well-known groups in the Dolomiti Friulane: the Spalti di Toro and Monfalconi.
The valley is a fine example of the landscape in this area, with imposing cliffs of Dolomite rock and deep valleys carved by wild streams running through them, creating large flows of debris that are continuously on the move. Here nature is wild and free and the only traces of man are flat areas on the valley floor for grazing.
The predominant rock in the Dolomiti Friulane is Main Dolomite, which was deposited towards the end of the Triassic period on an extensive flood plain, showing the early tendency to trap poorly oxygenated basins (Forni Dolomite). Many dinosaur footprints from the late Triassic period have been found here.
