The Bocksruck is 1763  m above sea level. A. high mountain massif of the Rottenmann and Wölzer Tauern in the Upper Mur Valley , Styria .

Location and landscape

The Bocksruck rises near Judenburg , westward upstream from the Judenburg basin (Aichfeld) to the Wölztal near Scheifling , north in the Mur valley to the Pölstal .

Like the other southern valleys of the Niedere Tauern in the area, the Pöls and Wölztal valleys clearly face southeast. The Mur, on the other hand, forms an arc to the north between Judenburg and Scheifling, so that the Bocksruck also has an arc-shaped west-east extension. It is a little indented, mostly wooded ridge of low mountain range , which extends with its significantly lower side mountains for almost 30 kilometers.

Classification, boundary, structure and summit

The massif is one of the Wölzer Tauern or Rottenmanner and Wölzer Tauern ( Alpine Club division ). It is an offshoot of the Schießeck  ( 2275  m above sea level ), a side ridge of the Niedere Tauern am Hohenwart . As is customary in the area, it forms the eastern foothills of the Murberge , the southern mountain range of the Niedere Tauern between Murtal and Murparalleltal . The Bocksruck group has the number 2632 in the mountain group structure according to Trimmel , belongs to the Wölzer Tauern (2630). It circumscribes itself:

The actual Bocksruck massif stretches along the Mur from the Pölshals saddle  ( 806  m above sea level ) at Pöls to Scheifling and the Schönberg valley . The main summit rises on the north-western edge of the Bergstock above the Hocheggersattel ( Gellsee ). The south flank of the massif breaks abruptly over 800 meters in altitude into the Murtal, the north flank to the upper Gföllergraben over 400 meters. It has two main ridges:

  • The one that travels eastward from the Bocksruck summit with the Habring  ( 1497  m above sea level ) as the main summit, also called the Bocksruck ridge ,
  • As well as the ridge with the Frauenkogel  ( 1627  m above sea level ) that extends south .

Between Judenburg and Pölshals, where the Mur and the lower Pöls river run largely parallel, the elongated Falkenberg  ( 1158  m above sea level ) extends as a foothill. Trimmel already counts this  as part of the Gaalereck group (2641, as part of the Seckauer Tauern ).

To the west, between Schoenberg and Oberwölz, on the saddle of Hinteralm (about  1160  m above sea level. A. ) adjacent, the rises Dürnberg  (1546/ 1544  m above sea level. A. ). Its assignment to the Bocksruck group is mainly based on the course of the Murparallel valley, otherwise it can also be seen as an independent foothill of the Schießeck massif.

North of the Bocksruck rise the Rossalm  ( 1894  m above sea level ) and the Schönberg  ( 1943  m above sea level , with Gföllerriegel) of the Wölzer Tauern (after Trimmel Pusterwald  2633). To the east is the Hölzlberg  ( 1589  m above sea level ) of the Gaaler ridge on the northern edge of the Aichfeld (Trimmel Gaalereck 2641). In the south is the Schafkogel - Weißeck ridge  ( 1743  m above sea level ) of the Seetal Alps and the Kreuzeck  ( 1459  m above sea level ) of the Neumarkt pass landscape (group of the Zirbitzkogel , Trimmel 2763). The Pleschaitz rises to the west  ( 1797  m above sea level , Trimmel Stolzalpe  2745, Murauer Berge ).

geology

The massif is formed from the feldspar - mica slate of the Wölzer crystalline ( old crystalline of the Middle Eastern Alps ). Are In Storage lenses of pegmatites and layers of amphibolite . It appears in the form of a trough , on the eastern edge in the Mur and Pölstal (and also continued at the Judenburg foot of the Seetal Alps) a lower floor of garnet- mica slate appears with amphibolite, biotite slate and marbles . The top floor of the Mulde appears at the Wölzer Dürnberg-Südfuß and around Schönberg, with various mica schists (including a formation of the Friesach half-window ) and limestone (group of the Murau limestone of the Devonian ), it represents a transition facies to the Upper Eastern Alpine Murau Paleozoic .

The massif is of geological faults embossed, Mur-Mürz-Furche and Murparalleltal (here the Gföllertal-Blabach disorder and Pölstalstörung ) belong to Norische Valley , south-north highlights the Pölshalsstörung . The syncline probably belongs to the thrust complex of the Murau Paleozoic (metamorphic Old Paleozoic of the Gurktal Nappe ) in the area of ​​the Neumarkt pass landscape .

The southern flank was dominated by the Murtal Glacier , which only formed a side tongue here; the entire glacier followed the pre- glacial runoff of the Mur / Olsa river and flowed off to Carinthia via Neumarkt. The summit corridor of the Bocksruck represents an old valley level of the pre-glacial main valley. The Murtaler tongue ended during the maximum freezing at Judenburg am Grünhübl , and also overflowed the Pölshals, where it formed a lobus-shaped glacier tongue in the Pölstal. The Pöls itself may have been the old upper course of the feeder to the Mur (which once came from the upper Ennstal) in the Ice Age.

Development and ways

The massif is densely developed with forest roads and easily accessible from all sides.

In spring 2019, a priority zone for the expansion of the wind power plant was under discussion (Bocksruck-Habring) . It was planned on the ridge between the Bocksruck and Habring summits. It was probably dropped after protests from the surrounding communities. To the north, on Schönberg, has been the highest wind farm in Europe at the time, the Tauern wind farm ( Oberzeiring priority zone ).
