The Eastern Sauerland mountain range is a major natural spatial unit in eastern North Rhine-Westphalia and north-western Hesse. The landscape bears the code number 332 within the main unit group 33 ( Süderbergland ) and covers the (northern) Rothaargebirge (main unit 333) to the east to the West Hessian mountains (main unit group 34). To the north it borders on the Paderborn plateau (362) in the Upper Weserbergland (main unit group 36), to the south with the Gladenbacher Bergland (320) on part of the natural Westerwald (Main unit group 32).

The East Sauerland mountain range is bounded roughly to the northwest by the Rhine-Weser watershed between the towns of Brilon (west) and Marsberg (east), and to the south by the upper reaches of the Lahn between Biedenkopf and Sterzhausen .

Adjacent natural areas

To the north is the Paderborn plateau (main unit 362), to the northeast the Egge Mountains (363) - both parts of the Lower Saxony mountainous region . On the other hand, three parts of the West Hessian mountainous region border to the east , namely the Waldecker Tafel (340) in the north , the Kellerwald (344) in the middle and the Burgwald (345) in the south . These landscapes differ significantly from the Rothaargebirge bordering to the west (with the Hochsauerland), to which the west of the (historical) Upland also belongs, while the east is part of the mountain range.

Natural characteristics

The landscapes surrounding the edge of the mountain differ significantly in terms of their geological structure and the clearly deviating landscape reliefs ( geomorphology ) as well as their respective climatic conditions.

geology

While the East Sauerland mountain range, just like the Rothaar Mountains adjoining it to the west, originates from the earlier Paleozoic era , the landscapes adjoining it to the east are attributed to the much more recent Hessian Bruchschollentafelland, the formation of which mainly took place in the Mesozoic Era.

The East Sauerland main saddle is built from rocks from the Devonian and Carboniferous . This sequence of partly strongly folded, Middle Paleozoic rocks (Upper Devonian and Lower Carboniferous slate, pebble slate, limestone and sandstone, partly with interposed tufa layers) plunge into the northeast under the late Paleozoic-early Mesozoic clays, carbonates and sandstones of the Waldeck Upland.

In contrast, the characteristic rocks of the Hessian Bruchschollentafelland region to the east (shell limestone, red sandstone, marl, gypsum and claystone) come from the Triassic and Jurassic ages .

The Kellerwald plays a special role here, as it comes from the Paleozoic Era - like the Rothaargebirge and Ostrand - and, in terms of rock structure, can also be assigned to the Rhenish Slate Mountains , on the other hand it is clearly located on the West Hessian Bruchscholle, from which it protrudes like a clump.

climate

Since the eastern edge of the Sauerland is in the rain shadow of the Rothaargebirge, the annual precipitation is halved from west to east from up to 1200 mm to barely more than 600 mm, while the mean daytime temperature is around 2 ° C from 6 to 7 ° C to 8 to 9 ° C increases.

Soil and vegetation

Soil conditions and use of the Eastern Sauerland mountain range are diverse and range from mixed forest landscapes ( bagpipe foreheads , Waldstruth ) to well-developed agricultural landscapes ( Medebacher Bucht , Upland ) to areas in the north where the mining of mineral resources plays a major role ( Marsberg copper slate , Ore mining in lead washing ).

Rivers

Although the Rhine-Weser watershed crosses the East Sauerland mountain range twice, this takes place in distinctly peripheral locations in the north and south, so that almost the entire area drains east to the Weser via Eder and Diemel .

Together with the abundance of precipitation in the Rothaargebirge, the low water storage capacity of the slate rocks on the edge of the mountain leads to a high risk of flooding, which has given rise to the construction of the Diemel Reservoir in the north and the Edertal Reservoir (east on the other side, in the northern Kellerwald).

Natural structure

The Süderbergland is structured as follows:
