Piesberg

The Piesberg is a mountain in Osnabrück (Lower Saxony) and North of Eversburg and East from Pye and on the South Rim of community Wallenhorst ( a part of the Piesberg belongs to Wallenhorst).
His Height is 188 meters above sea level.

His Development is due to the carbon-age. 300 million years ago the area was a large coastal plain over long periods of time was bathed by large, branched Riversystems. Deposite these rivers large amounts of coarse sands and sometimes gravel, the later were strengthened particularly hard sandstone and conglomerate (from gravel). In Phases of higher groundwater levels (which probably associated with sea fluctuations), also sound were emerging in slower flowing water, the so-called shale was later. Temporarily developed also a real swamp forest, whose remains today both as bed of coals to find are (compressed plant material), on the other hand, as various Plant fossils in the shale.

Which layers of earth of the following Triassic overlayed these rocks of Karbons the Osnabrücker mountains raised up by forces from the Earth's interior was. May mountains where arose under the Northern Osnabrück also a " Magma bubble"- a so-called Pluton. The properties of coal and the sandstone draw attention to a strong heating. By erosion, were the old inter alia by the ice age glaciers rock layers again exposed.

The Name Piesberg can be attributed it, the mountain earlier to the village Pye belonged. It was therefore " Pyes mountain", what later became Piesberg. Most Piesberg is the hard sandstone today in a large quarry (also called carbon-Quarzit) mined.

Which now closed landfill at southfacing of Piesberges was in a created former quarry. You can find the Piesberge-sandstone in Osnabrück city on some buildings and especially as paving stone.
Coal was mined until 1952 until 1898 and very weak (to Lifaqane).
