The Rieserfernergruppe (Italian: Gruppo delle Vedrette di Ries ) is a mountain range in the central Alps. Together with Ankogelgroup, Goldberg Group, the Glockner group, Schobergruppe Kreuzeckgruppe, Granatspitzgruppe, Venedigergruppe and Villgratner mountains it is part of the Hohe Tauern. The Rieserfernergruppe covers the Austrian province of Tyrol and the Italian province of South Tyrol ( Trentino -Alto Adige ). The mountain range is situated mostly in South Tyrol, where again a large portion is provided in the Rieserferner Ahrn under protection.
The Rieserfernergruppe forms the southwestern part of the Hohe Tauern, their rich foothills in the southwest to Brunico in Val Pusteria. It has its name from the mountain Vedrette, a glacier on the northern flank between Hochgall (highest peak with 3436 m slm ) and Schneebigem Nock ( 3358 m slm ).
The Rieserfernergruppe has in comparison to other mountain ranges of only a small extent. However, it is renowned for its distinctive and steep, partially glaciated peak with mountain climbers and hikers.
The Rieserfernergruppe borders the following other mountain groups in the Alps:
- Venedigergruppe ( in the north)
- Villgratner mountains ( in the southeast )
- Dolomites ( in the south)
- Zillertal Alps ( in the west)
In the north the Klammljoch forms the border. To the east the boundary goes from there along the Arventalbachs on the Jagdhausalm to the confluence with the Schwarzach. To the west the boundary runs from Klammjoch along the Klammlbachs to the confluence with the Knuttenbach. In the east, the boundary runs along the Schwarzach to the confluence of the Staller Almbachs. In the southeast and south, the boundary runs along the Staller Almbachs the Staller Sattel. From there it goes along to the Antholz Valley to Olang in Val Pusteria and downstream along the Rienz to Brunico. In the west the boundary is formed by the Tures valley and the Reintal. It continues in Knuttental to the confluence of the gorge creek.
The Klammljoch connects the Rieserfernergruppe with the Venediger. The Staller Sattel provides the connection to the Villgratner mountains.
The middle part of Rieserfernergruppe is, geographically speaking, from a special granite rock that is present here in the form of a plutonic rocks. This plutonite bulges and breaks through the so-called Schieferhülle, sediment remains of the Piedmont Ocean, through a breakup of the supercontinent Pangaea was created from the Jurassic period, about 150 million years ago to the present continents. The rocks of the so-called old gneiss, which forms the basis in this area of the Central Alps, was refolded and reorganized so that occur west of the Schneebiger Nock and Vedrette hut from the previous Variscan orogeny only relics in the form of Pegmatitgesteinen during alpidischen orogeny. From pre-Alpine period also saw the augen gneiss of Campo Tures.
Towards the end of alpidischen orogeny, about 30 million years ago, the Vedrette - plutonite originated from a melt in great depth and ascended. Exposed by erosion of the overlying shale shell, he forms the central part of the Rieserfernergruppe. The rock consists of granites related species diorite and tonalite. Feldspar, quartz, biotite and hornblende are the main components of this so-called Vedrette granite. Hochgall, Wildgall, the neighboring skimmed stones and mountains on the New Barmer hut are constructed from this material. The Schneebige Nock in the West, however, is covered by originary dark gneiss. The heat of the ascending magma body also changed the surrounding gneisses, which garnet crystals, andalusite and numerous dykes originated. A side path of the Vedrette - Plutonits rose in the south, west of Antholz, on Zinsnock on. It is connected to the main body and is above ground separated by resting rock in the Black Wall.
In the Rieserfernergruppe there are about 30 points higher than 3,000 m. The best known and most important peaks are:
- Hochgall ( 3436 m s.l.m. )
- Schneebiger Nock ( 3358 m s.l.m. )
- Wildgall ( 3273 m s.l.m. )
- Magerstein ( 3273 m s.l.m. )
- Steering Stein ( 3237 m s.l.m. )
- Large wind band ( Lane Bach Spitz ) ( 3041 m slm ), western corner of the group
- Triangle top ( 3031 m slm ), the northernmost of the three-thousand group
