Alb-Wutach area
The Alb-Wutach area is a natural area of the Neckar and Tauber-Gäuplatten (main unit 12) in the south-west German layer level country . It leads the number 120 in the systematics of the manual of the natural spatial structure of Germany . The classification was based on the coherent shell limestone formation .
Natural structure
In the Geographical Land Survey of the Federal Office for Regional Studies , the Alb-Wutach area was rededicated to the main unit and described in two parts on the individual sheets 1: 200,000 185 Freiburg im Breisgau and 186 Konstanz published in 1964 :
- 120 1 Klettgau layer level land
- 120 1 .0 Waldshut shell limestone slabs
- 120 1 .00 Steina shell limestone slabs
- 120 1 .01 Waldkirch-Waldshuter-Muschelkalkriedel
- 120 1 .02 Buch-Birkinger gravel surfaces
- 120 1 .10 Hallau back
- 120 1 .20 Klettgau main valley
- 120 1 .21 Koblenz-Tiengener estuary (with the Wutach estuary and the Ettikoner Lauffen )
- 120 1 .30 Large Klettgau back (with Küssaburg foreland)
- 120 1 .0 Waldshut shell limestone slabs
- 120 2 Middle Wutachland
- 120 2 .0 Bonndorf-Löffinger Muschelkalkhochland
- 120 2 .00 Bonndorf Muschelkalkhochland
- 120 2 .01 Löffinger Muschelkalkhochland
- 120 2 .1 Eichberg-Hochranden-Foreland
- 120 2 .10 High Ridge Foreland
- 120 2 .20 Eichberg foreland
- 120 2 .0 Bonndorf-Löffinger Muschelkalkhochland
Adjacent natural areas are:
- Baar (No. 121) in the north
- Southern Black Forest (No. 155) in the west
- Swiss beetroot (No. 090) and Hegaualb (No. 091) in the east
The Upper Rhine borders in the south and Switzerland behind it .
geology
The Alb-Wutach area is the southernmost unit of the Gäuplatten. Significant differences in altitude (from 230 m in the south to 900 m in the north) and deeply cut valley furrows are characteristic. Within the area, one can distinguish between the Wutach and Hochrhein valleys , the highly fragmented Muschelkalk plateaus, which take up the largest area, and the Neunkirchen valley in Klettgau with the Klettgau gully and the heights of the Klettgaualb in the south. Within the area, all layers are cut from the basement to the Weissjura.
The Muschelkalk plateau slopes to the east and south. Most of the sloping areas are used for arable farming. The valleys and valley flanks are mostly wooded, in parts they are populated by small villages. Coniferous forests (spruce and fir) dominate, but deciduous forests predominate in the Wutach Gorge .
In the south-eastern area, the Neunkirchen lowland joins, which was once formed by the Urrhein and is characterized by gravel from the meltwater channel of the last ice age (Klettgau channel). The gravel is partially covered with loess. Mostly arable farming is practiced, in favorable locations viticulture and the cultivation of noble fruits are possible. The Klettgau-Alb rises south of it. Beech forests, small villages and individual farms alternate here.
