Waters and glaciers
Stelvio National Park extends around a central area of over 10,000 ha, which is covered by eternal snow and ice, where glacier peaks dominate the scenery and at the same time provide the valleys with their most precious asset, water! Monte Cevedale, symbol of the Trentino sector of the Park, emerges from the centre of this icy world. From there, and from many other lateral glaciers, narrow and shiny ribbons of water, like arteries, flow in all directions; water that runs into little brooks, still ponds, wild streams and rushes down thunderous waterfalls. From an hydrological point of view, the Trentino part of the Park is divided into Val di Peio and Val di Rabbi, which again branch off into many lateral valleys, such as Val del Monte, Val de la Mare, Val Cércen and Val di Saènt. In the wide, open spaces of the highest mountain regions, numerous lakes enclose large quantities of water that have gathered in morphological depression and small glacial bowls. Some of them are Lago Covel, Lago Marmotte, Lago Lungo, Lago Sternai, Lago Corvo, and finally the reservoirs of Pian Palù and Careser. Yet, man has used the valuable resource water not only for producing hydroelectric energy but also for therapeutic purposes. In fact, the creative properties of the thermal baths of Peio and Rabbi have been known since the 17th century. The waters of Peio contain carbon and sulphur, the Rabbi springs are alkaline, rich in iron, salts and carbonic acid, which makes their water fizzy.
