Schnettker Bridge on the western slope of the Dortmund ridge to the Emscher valley

The Dortmunder Ridge is a submontane mountain range in the eastern Ruhr area . It extends from the south-eastern city limits of Dortmund to the municipality of Holzwickede over the east of Dortmund and the southern Dortmund city center to the west to the valley of the Emscher.

Naturally , the Dortmunder Ridge (code number 542.20) belongs to the so-called Oberbörden (542.2) of the main unit Hellwegbörden (main unit 542) in the southwest of the latter and in the south of the main unit group Westphalian Bay ( main unit group 42). This is why it is also known as the Dortmund Börde .

location

The Dortmunder ridge joins the Werl-Unnaer Börde at the height of the Dortmund airport on the city limits of Dortmund to Holzwickede near the eastern city limit to Unna and to the Haarstrang south of it on Holzwickeder municipality. It runs through the Dortmund metropolitan area of the eastern suburbs Wickede , Sölde , isopods , Neuasseln , Aplerbeck , Brackel , Stoke and Wambel , the northern slopes of Horde and the southern city with the garden city and urban development on both sides of Westfalendamm and Rheinlanddamm up to the Emschertal in the area of ​​the Schnettker bridge . Its extension is about 15 km in a west-east direction. At the junction with the Haarstrang at the Emscher source , its maximum north-south extension is approx. 4.5 km, further west less than 3.5 km. The national road 1 extends across the east-west distance of the Dortmund back.

Landscape characteristics

The ridge extends the Werl-Unnaer Börde to the southwest and connects to the ridge of the Haarstrang to the west and to that of the Ardey Mountains to the north . While the Oberbörden adjoining to the east, including the Werl-Unnaer, only represent a north-facing roof of the Haar, the Dortmund ridge also falls south to the Witten-Hörder Mulde and to the west to the Emschertal , which here still runs in a south-north direction , which is why it has the characteristic of a mountain spur.

Elevation profile

The Dortmunder Ridge in the east of the Hohe Malterse , above the Holzwickeder districts of Natorp and Rausingen at the confluence of Vincenz-Wiederholt-Straße with Chaussee , reaches its highest independent height at 146.5  m directly at the airport site . It also reaches similar height values ​​roughly at the seam to the Haarstrang near Sölderholz and in the extension to the Ardey near Aplerbecker Mark .

To the west, the elevations towards Dortmund city center drop to 100  m above sea level. NN (eastern abutment of the Schnettker Bridge).

The Emscher

In Holzwickede, district of Dudenroth , the Emscher rises at the junction of the hairline to the southeast slope of the Dortmund ridge ( Herdicker Haar ) . This flows around the ridge in the north of the Witten-Hörder Mulde, initially south in an east-west direction, in order to change its course to the south-west of Dortmund city center to the north and to flank it to the west along with the ridge that flattens to the west.
