The Dinsterbach is an approximately 3 km long karst brook in the southern Harz Zechstein belt . It flows near the southern Harz district of Questenberg in the Saxony-Anhalt district of Mansfeld-Südharz in the nature reserve Gipskarstlandschaft Questenberg , where it disappears into the gypsum underground.
Geographical location
The Dinsterbach gathers on the eastern slope of the Hohe Kopf (457 m) at a height of approx. 460 m in the Karst Landscape Biosphere Reserve of the Southern Harz Mountains of the Lower Harz . It spreads in the municipality of Südharz - 1.5 km east of Questenberg , about 2 km west of Hainrode and about 3 km south of Rotha .
Dinsterbachtal
The Dinsterbach enters the Karst for the first time at the loop between Questenberg and Hainrode. Below the bridge, the water has dug a steep river bed “Gloomy Valley” into the flat Zechstein limestone . Since the rock is water-conducting due to its fissured and flat bedding, the stream already loses part of its water here in the infiltration section.
The copper slate lying under the Zechstein limestone collides with the sandy clay slate of the Carboniferous in a northerly direction and ends there. Its ore content is very low and therefore not exploitable. In 1934 a tunnel was driven into the mountain, which after a length of 100 m reached the seam. As Mansfeld AG wanted to show with this tunnel drive that it was still interested in the Questenberg area, the tunnel had achieved its goal. Today the tunnel mouth is walled up and only accessible to bats and amphibians through an opening.
Dinsterbach swell
The Dinsterbachschwinde is one of the most impressive ponors in the southern Harz. After approx. 800 m through the "Düstere Tal", the small Harz stream disappears in the karst underground of the Sangerhaus anhydrite . The shrinkage point, a wall shrinkage with large upstream debris heaps, changes continuously. Parts of the 30 m high cliff keep breaking and spilling the cave entrance behind the debris. In the summer, the creek partially dries up completely. In spring it can carry up to 100 l / s of water. Since the water never came into contact with the gypsum up to this point, it can continue to dissolve rock quickly and create large cavities. Coloration of the water showed that smaller amounts were escaping again in the neighboring Nassetal. After 1985 the water looked for new ways. It probably flows underground to the Helmetal . The Schwinde has been a nature reserve since 1988 .
Haselborn shrinkage
About 700 m east of Questenberg, the Haselbach disappears into a deep sinkhole . The Haselbornschwinde is probably an old shrinkage of the Dinsterbach above, which seeped into the subsoil here before moving its current drainage hole back uphill. It is not known where the water flows underground.
Normally the Haselborn seeps into the deepest part of the basin after a short run. If the water flow is very strong, a lake forms.
