The 3,358 m high Monte Nevoso, second-highest mountain of the Vedrette di Ries Group, is also known as Ruthnerhorn.
The pyramidal Monte Nevoso (Schneebige Nock in German) or Ruthnerhorn (named after Anton von Ruthner), is with its 3,358 m the second-highest mountain of the Gruppo delle Vedrette di Ries group, only exceeded by the 80 m higher Monte Collalto. The Monte Nevoso is located in the border area of South and East Tyrol, still on South Tyrolean territory in the Vedrette di Ries-Aurina Nature Park.
The mountain is surrounded by glaciers, among them the Monte Nevoso glacier. Its neighbours in the area between Riva di Tures and the Valle di Anterselva valley are the Frauenköpfl (3,251 m a.s.l.), Monte Magro (3,273 m a.s.l.) and the Gatternock (2,888 m a.s.l.).
In 1866 the Monte Nevoso was climbed for the first time, principal and part of the alpinists was Archduke Rainer Ferdinand of Austria. Today the mountain can be scaled via the Kasseler Mountain Hut or the Vedrette di Ries Mountain Hut. In winter it can be climbed as part of a ski tour.
