Salzach Glacier

from Wikipedia, the free encyclopedia

The Salzach Glacier was the Ice Age glacier of the Alpine rivers Salzach and Saalach .

It flowed through the whole of today's Salzachtaal and Saalachtaal and formed extensive foreland glaciers. During the Würm high glacial period it extended over an area of ​​6000 km². It reached in the west to the Gerlos Pass , in the south to the main Alpine ridge and in the east to the Wagrainer Höhe . The maximum total length of the glacier from the slope of the Hohe Tauern to the outermost terminal moraines at Nunreuth was 128 km. The length of the snow-free glacier tongues on the Saalach glacier from Jettenberg or Reichenhall and on the Salzach from Golling or Hallein was around 60 km. The area of ​​the moraine area was approx. 1700 km², the young moraine area was 1100 km².

In the Salzburg Basin, in the area of ​​today's Salzburg, the streams from the Salzach and Saalach valleys combined and formed a common foreland glacier.

Main stream (Salzachtal glacier)

The maximum height of the ice flow of the glacier in the upper Salzach valley was 2200 m, at Bischofshofen and Saalfelden the height was approx. 2000 m, north of the pass Lueg the height was 1300 to 1400 m, in the Salzburg basin approx. 1000 m MH

Foreland ice compartments

In the north it fanned out into several branch basins. Three belts of moraines and gravel deposits formed, from which you can see the extent of the glacier:

  • The innermost is the moraine area of ​​the most recent Ice Age, the Worm Ice Age . It forms a semicircle with Salzburg as its center and a radius of approx. 40 km.
  • The older moraine and gravel area of ​​the Riss Ice Age is 4–6 km wide.
  • The outermost belt is formed by the Nagelfluh Islands, the top gravel of which often comes from the Minimum Ice Age .

Several branch basins were created. From west to east these are: the Teisendorfer basin, the basin of the Waginger - Tachinger See with the Surtal basin , the Tittmoninger basin, the furrow of the Ibmer and Bürmoos , the Oichtental basin, the basin of the Trumer lakes and the basin of the Seekirchner basin. and Wallersees .
