Ardey Hills
The Ardey Mountains - also known as rare or of the Ardey - is a up to 273.8 m above sea level. NN high in many places wooded mountain range in the area of the independent city of Dortmund and in Ennepe -Ruhr-Kreis and the district of Unna in North Rhine -Westphalia ( Germany ). It belongs to the right - Rhenish Slate Mountains and a small area to the low Bergisch- Märkischen hills.
The Ardey Mountains are located north of the Ruhr and is managed according to the manual of the biogeographic division of Germany under the name Ardey as natural spatial unit with the atomic number 3371.5. This natural area is doing in certain geographic subunits Ardey height ( order number 3371.50 ) and 3371.51 Südardeywände divided.
Geography
Geographical location
The Ardey Mountain range that separates along with the hair strand roughly in east-west direction, two natural areas large units: the Westphalian bay with Emscher valley and Hellweg Börden in the north from Southshore Bergland with the Low Sauerland in the south, where the Ardey is, however, attributed to the Southshore mountain country and the hair strand of the Westphalian Bay.
Topographically considered is the Ardey mountains of the West foothills of the forest poor and predominantly agricultural hair strand. Not only cultural landscape but also geologically but it is from this distinction ( it is crucial near-surface carbon limit).
In the north the Ardey Mountains in the city of Dortmund passes gradually into the lowlands of the Westphalian Bay over the area of Munster country. South and west it is bounded by the Ruhr, in the valley, it usually falls off sharply with steep slopes. At the local slope, the maximum 165.2 m difference in altitude, located between the upper basin (approx. 261.5 m above sea level. NN ) and the Hengsteysee ( 96.3 m above sea level. NN ) are located, situated in the Herdecke pumped-storage power plant Koepchenwerk for energy used by hydropower.
The annual rainfall is 850 mm.
Towns
In or on Ardey mountains line the Ruhr these towns and cities - viewed from east-northeast to west southwest - together: Fröndenberg, Unna, Holzwickede, sword, Dortmund, Hagen, Herdecke, Weather and Witten.
Surveys
The highest elevation of the Ardeygebirges is the elongated ridge on the healing that rises to Herdecker district west of its core city. These and other surveys - sorted by height in meters ( m) above mean sea level ( MSL ):
- On the salvation ( 273.8 m), Herdecke
- Klusenberg ( 254.3 m), Dortmund - Syburg
- Ahlenberg ( 247.5 m), Herdecke
- Wartenberg ( 246.1 m), Witten
- Syberg ( 245.4 m), Dortmund - Syburg
- Harkortberg ( 231.5 m), weather
- Ebberg ( 222.3 m), sword
- Rehberg ( 197.9 m), Herdecke
- Hohenstein ( about 146 m), Witten
Geology and history
Mostly acidophilous sand and mudstones (so-called shale or slate ) and greywacke from the Carboniferous form the geological subsoil of Ardeygebirges, including the mined in quarries Ruhr sandstone. Ardey and hair strand together limited the advance of the northern ice sheet of the last ice ages.
Landscape
Along the Ruhr shows the Ardey mountains a predominantly mountainous character. Large differences in altitude, rocky cliffs and deep V-shaped valleys dominate the landscape here. Seen from the north and east of the mountains, however, shows the Ardey of his gentle side. Here are wide sweeping forest and meadow hill. The proximity to the cities of Dortmund and Witten the northern edge of the mountain is strong urban sprawl a preferred residential area and for this reason accordingly.
Mostly the ridge ( " harrow ") of the Ardey are covered with beech forests. The slopes are furrowed by pronounced V-shaped valleys of small streams, so-called Siepen and thereby divided small areas. The Ardey Mountains is an ancient cultural landscape. Traces of historical forms of forest use such as coppicing, forest grazing and charcoal burning are still to be found in many places today.
Hiking
On the heights of Ardeygebirges a particularly attractive section of the Ruhr height path of the Sauerland mountain association of the source to the mouth of the Ruhr with many vantage points, especially in the Ruhr valley runs. Also the Westphalia trail leads over the mountains Ardey. Among the local hiking trails include the Witten trail, the trail Dortmund and Herdecke trail.
