The Ardey Mountains [ 'aːɐ̯.daɪ̯.ɡəˌbɪʁ.ɡə ] - also called the or less often the Ardey - is up to 273.8 m above sea level. NHN high, wooded ridge in many places in the area of the independent city of Dortmund and in the Ennepe-Ruhr district and Unna district in North Rhine-Westphalia . Located north of the Ruhr, it is part of the Right- Rhenish Slate Mountains and, on a small scale, the Niederbergisch-Märkisch hill country .
geography
location
The Ardey Mountains, together with the Haarstrang, roughly separates two major natural spatial units in an east-west direction: The Westphalian Bay with Emscher Niederung and Hellwegbörden in the north from the Southern Bergland with the Lower Sauerland in the south, whereby the Ardey belongs to the Southern Bergland and the Haarstrang to the Westphalian Bay becomes.
Viewed topographically , the Ardey Mountains are the western foothills of the poorly forested and predominantly agriculturally used hair strand. However, it is differentiated from this not only in terms of cultural landscape, but also geologically (the near-surface carbon limit is decisive ).
In the north, the Ardey Mountains in the city of Dortmund gradually merge into the lowlands of the Westphalian Bay in the Münsterland area . It is bordered to the south and west by the Ruhr , in whose valley it mostly drops steeply with steep slopes. At the local slope, the maximum is 165.2 m vertical drop, located between the upper reservoir (about 261.5 m ) and the Hengsteysee ( 96.3 m , are located) from in Herdecke located Pumpspeicherkraftwerk Koepchenwerk used to produce energy from hydropower.
The annual rainfall is 850 mm.
Natural allocation
According to the handbook of the natural spatial structure of Germany , the Ardey Mountains form the natural area Ardey (337 1 ) in the main natural unit group Süderbergland (No. 33), in the main unit Bergisch-Sauerland lowlands (337) and in the subunit Niederbergisch-Märkisches Hügelland (337 1 ) . 5). This natural area is divided into the Ardeyhöhe (337 1 .50) and the south Ardey walls 337 1 .51.
Localities
In or on the Ardey Mountains, from east to west, are the cities of Schwerte , Dortmund , Herdecke , Wetter and Witten .
Surveys
The highest elevation of the Ardey Mountains is the elongated ridge Auf dem Heil , which rises on the Herdecker district to the west of its core town. These and other elevations are - sorted by height in meters (m) above sea level (NHN):

Geology and history
Predominantly acidic sand and clay stones (so-called slate clays or clay slate ) as well as Grauwacken from the carbon form the geological subsoil of the Ardey Mountains, including the Ruhr sandstone, which is mined in large quarries . The Ardey and Haarstrang jointly limited the advance of the northern inland ice of the last ice ages . The Ardey Mountains were also the site of intensive coal mining. Numerous day breaks still bear witness to this. One of the pits was the Marienberger Erbstolln .
landscape
Along the Ruhr, the Ardey Mountains have a decidedly mountainous character. Large differences in altitude, rocky steep slopes and deep notched valleys characterize the landscape here. Seen from the north and east, however, the Ardey Mountains show their gentle side. Here there are sweeping forest and meadow hills. Due to the proximity to the cities of Dortmund and Witten , the northern edge of the mountains is a preferred residential area and, for this reason, is correspondingly highly sprawled .
The mountain ridges ("harrows") of the Ardey are predominantly covered with beech forests. The slopes are furrowed by pronounced notch valleys of small streams, so-called sieves , and are therefore divided into small areas. The Ardey Mountains are an old cultural landscape . Traces of historical forest use forms like Niederwald , forest grazing and economic charcoal today to find in many places.
The areas outside of built-up areas with a development plan are classified as protected areas such as B. Protected landscape area Ardey forests and nature reserve Ruhr slopes Hohensyburg designated.
hike
On the heights of the Ardey Mountains, a particularly attractive section of the Ruhrhöhenweg of the Sauerland Mountain Association runs from the source to the mouth of the Ruhr with numerous vantage points, especially into the Ruhr Valley. The Westphalia hiking trail also leads over the Ardey Mountains. The local hiking trails include the Witten circular route , the Dortmund circular route and the Herdeck circular route .
