The Schalke is a mountain, 762 m above sea level (NN), in the Upper Harz in the German state of Lower Saxony. It lies in Goslar district north of Clausthal-Zellerfeld and west of Schulenberg.
The Upper Harz Mining Museum is a museum of technological and cultural history in Clausthal-Zellerfeld in the Harz mountains of central Germany. It is one of the oldest technological museums in Germany and concentrates on the history and presentation of mining in the Upper Harz up to the 19th century.
The Aschentalshalbe is a ridge in the Harz Mountains of Germany that is up to 685 m above sea level (NN). It lies south of the village of Sieber in the unincorporated area of Harz in the district of Göttingen in the state of Lower Saxony.
The Upper Harz Ditches are hillside ditches, running roughly parallel to the contour lines, that were laid out in the Upper Harz in Germany from the 16th to the 19th centuries to supply water power to the silver mines there. They are an important component of the Upper Harz Water Regale, a historical water system that is now a cultural monument.
The Oderteich is an historic reservoir about seven kilometres northeast of Sankt Andreasberg in the Upper Harz in central Germany. It was built by miners from St. Andreasberg in the years 1715 to 1722 and, today, is an important component of the water supply network known as the Upper Harz Water Regale. Moreover, for 170 years, from the time it was completed to the end of the 19th century, the Oderteich had the largest dam in Germany. The dam lies at a height of 725 m above NN by the B 242 federal highway, about a kilometre west of its intersection with the B 4.
The Upper Harz Water Tunnels are part of the Upper Harz Water Regale - a network of reservoirs, ditches, tunnels and other structures in the Harz mountains of central Germany. The German term Wasserlauf refers to the underground element of the network of watercourses used in the historic silver mining industry of the Upper Harz. This network of ditches and tunnels was used to supply the mines with headrace waters for their water wheels from the 16th century onwards. In the system of the Upper Harz Water Regale there are over 35 such tunnels with a total length of about 30 km.
The Upper Harz Ponds are found mainly around the mining town of Clausthal-Zellerfeld and the nearby villages of Buntenbock and Hahnenklee in the Upper Harz mountains of central Germany. There are around 70 ponds in total, both large and small. They were built by the miners of the Upper Harz, mostly between the 16th and 18th centuries, and are important components of the cultural monument known as the Upper Harz Water Regale - a network of dams, ditches, ponds and tunnels that was built to supply much-needed water power for the mining industry in the Harz mountains. Today the Water Regale is being proposed as a UNESCO World Heritage Site. About half the dammed ponds are classified today as reservoirs, but they have now become characteristic features of the Upper Harz and are home to some extremely rare plant and animal species.
The Dyke Ditch is the longest artificial ditch in the Upper Harz in central Germany. Its purpose was to collect surface runoff for the operation of the Upper Harz mining industry from precipitation-heavy regions a long way away. It was laid in 1732 and continually extended eastwards until 1827. Its original length was about 25 km; this was successively shortened by water tunnels between 1820 and 1861 to around 19 km. It is a central component of the Upper Harz Water Regale. Its takes its name from the Sperberhai Dyke which is, in fact, an embankment on top of which the Dyke Ditch runs in an aqueduct in order to cross a depression.
Mining in the Upper Harz region of central Germany was a major industry for several centuries, especially for the production of silver, lead, copper, and, latterly, zinc as well. Great wealth was accumulated from the mining of silver from the 16th to the 19th centuries, as well as from important technical inventions. The centre of the mining industry was the group of seven Upper Harz mining towns of Clausthal, Zellerfeld, Sankt Andreasberg, Wildemann, Grund, Lautenthal und Altenau.
A Kunstteich is an historic German term for a man-made lake or pond associated with the mining industry and its technology. These ponds were created by the construction of barriers, typically dams and embankments, and were used to supply hydropower and water to the mines. Water stored in the reservoir was used for a variety of purposes. It was used to turn water wheels that in turn drove the various mechanical devices used in mining in earlier centuries, such as man engines. It was also used to produce power and drain the mines, or in the processing of ore. In principle, all Kunstteiche are small dam and reservoir installations. The oldest working dams in Germany are Kunstteiche.
Within the Lower Harz region are still many traces of the historical water management facilities used by the mining industry. In addition to water-carrying ditches and ponds, there are also long-abandoned ditches and dry pond beds. The Lower Harz Pond and Ditch System, which forms the major part of these old water management facilities, lies in the central Lower Harz, almost entirely within the borough of the present-day town of Harzgerode.
The Bärenbrucher Teich is an historic reservoir in the Harz Mountains of central Germany. It lies east of Buntenbock near Clausthal-Zellerfeld.
The Jägersbleeker Teich in the Harz Mountains of central Germany is a storage pond near the town of Clausthal-Zellerfeld in the county of Goslar in Lower Saxony. It is one of the Upper Harz Ponds that were created for the mining industry.
The Bergrat Müller Pond, named after a former mining director, Müller, in the Harz mountains of central Germany is a storage pond laid out from 1737 to 1738. It has an area of about 1.3 ha and lies in the forested southern part of the borough of Quedlinburg in the county of Harz in Saxony-Anhalt.
The Lower Grumbach Pond, usually just Grumbach Pond, is an old mining reservoir or Kunstteich between Hahnenklee and Wildemann in the Upper Harz mountains in Germany
