The Hohnsberg is a 241.9 meter high mountain in the area of the city of Bad Iburg in Lower Saxony . It has been the subject of geological research since the 19th century.
location
The Hohnsberg is part of the Teutoburg Forest . It is located northeast of the center of the city of Bad Iburg in the Palsterkamp state forest. To the south-west is the 269-meter-high Great Freeden , which is protected under the Fauna-Flora-Habitat Directive , and to the northwest is the 194.3-meter-high Limberg . The crash site of the Zeppelin LZ 7 with a memorial stone commemorating the accident in June 1910 is located north of the Hohnsberg summit. To the south lies the 225.5 meter high Sentruper Berg. The Düte rises east of the summit . The Hermannsweg Höhenweg , a 156-kilometer hiking trail over the ridge of the Teutoburg Forest, leads south along the Hohnsberg. It is part of a hiking trail around the summit.
Geology and research on the Hohnsberg
There are several former sandstone quarries on the wooded Hohnsberg, which is not populated. The mountain consists of Osning sandstone from the Lower Cretaceous. It is around 125 million years old. The sandstone has been quarried since the 18th century and used to build houses.
Geological research has been carried out at Hohnsberg since the second half of the 19th century, for the first time by the geologist and paleontologist Otto Weerth (1849–1930), who was born in Blomberg .
Weerth discovered the fossil of a large clam on Hohnsberg , which he named Pinna iburgensis Weerth . It is located in the Lippisches Landesmuseum in Detmold (North Rhine-Westphalia). Weerth reported on his find in the essay Die Fauna des Neocom sandstone in the Teutoburg Forest, which was published in Volume 2 of the Palaeontological Treatises in 1884 .
His discoveries include the petrification of cycad -Wedels Zamites iburgensis Hosius u. v. d. Marck . The naked man was described in 1880 by August Hosius (1825-1896) and Johann Wilhelm Carl Theodor Matthias von der Marck (1815-1900).
Finds by Otto Kanzler (1851–1924), whose research at Hohnsberg is documented for 1897 and 1898, can be found in the Bad Rothenfelde Museum , the Dr. Alfred Bauer Museum of Local History.
Other researchers at Hohnsberg were Adolf von Koenen and Karl Erich Andrée , whose doctoral supervisor was von Koenen. In his dissertation “The Teutoburg Forest near Iburg” from 1904, Andrée listed fossils from Hohnsberg, some of which are in the collection of the Georg-August University in Göttingen . Gerhard Keller (1903–1981) also conducted research at the Hohnsberg after the Second World War .
