Oder Dam

The Ravensberg is a 659 m high mountain in the South Harz mountains in the German state of Lower Saxony. It is relatively isolated and visible for a long way. It lies in the district of Göttingen, north of Bad Sachsa. The mountain top is crowned with a prominent 64 m high tower, which was built in 1970. This tower acted as a listening post during the Cold War; today it is used by Deutsche Telekom. The Ravensberg is a wonderful viewing point, and is also very easy to get to by car, a road about 3.5 km long, running up to the summit from Bad Sachsa. There is an old boundary stone, the Dreiherrenstein, on this road shortly before the summit. Until 1866 this was where the borders of the Kingdom of Prussia, Kingdom of Hanover and Duchy of Brunswick met. Today the Dreiherrenstein is the starting point for several walks, mountain bike routes and the South Harz cross-country skiing trail, that runs, for example, to the Stöberhai mountain and town of Braunlage. On the summit is a restaurant catering for day-trippers. There is also a skiing area with several downhill runs and 3 lifts.

The Stöberhai is a mountain the Harz highlands in Central Germany, immediately south of the Oder Dam and northwest of Wieda. At a height of 720 m above sea level (NN) it is the highest mountain in the South Harz. The origin of the name is uncertain, but it is suggested, that a charcoal burner called Stöber may have had his charcoal store (Hai) here.

The Steina Dam (German: Steinatalsperre) in the Harz Mountains of central Germany is a dam system comprising a dam, reservoir and waterworks near the village of Steina and belongs to the unincorporated area of Harz in the district of Göttingen in Lower Saxony. The dam was inaugurated on 19 November 1954 as a retention basin and has been a drinking water reservoir since 1958. Its 8.5 metre high dam impounds the Steina stream forming the Steina Reservoir (Steinastaubecken). It provides drinking water for the villages of Bad Sachsa, Osterhagen, Nüxei and Steina, which is why the surrounding woods are a water protection area.

The Wieda is a river in the German states of Lower Saxony and Thuringia. The Wieda has its source above the village of Wieda, flows through the village of Walkenried, the hamlet of Wiedigshof and the village of Gudersleben before discharging in the Harz river Zorge near Woffleben, a district of Ellrich. Its channel regularly dries up in the summer months - it sinks into the karst soil and reappears in other places as springs. Its most important tributary is the Uffe.

Schadenbeek is a small river of Lower Saxony, Germany. It flows into the Krumme Lutter north of Bad Lauterberg.

Silberhütte was once a village in the formerly free mining town of Sankt Andreasberg in the Harz mountains in Germany, but since its merger on 1 November 2011 it has been part of the borough of Braunlage. The name of the village goes back to the silver works that was existed here until 1912 and which smelted the ores from the mines around Sankt Andreasberg. According to Ließmann (2003), the smelting of the ores was carried out here soon after the opening of the Sankt Andreasberg silver mines. These naturally had a raised arsenic content. The silver works was located at the confluence of the Wäschegrundbach and the Sperrlutter - so that there was enough water power to drive the machines in the smeltery. Not only did the smelting workers here have to endure toxic emissions but, even in older accounts, there is talk of the massive nuisance caused by toxic, arsenic-containing, fumes from the smeltery which, in unfavourable weather conditions, swept into the town and occasionally forced the people living there to flee. The first smelting works are recorded at this locality around 1550. At the beginning of the Thirty Years' War, the smeltery was sold and demolished. When the silver mining industry flourished again in the 1680s, a new larger smelting works was built, which - rebuilt and extended several times - was in operation until 1912. In 1836, the responsible mining authority allowed the construction of a separate arsenic works on the Silberhütte site. In addition to arsenic trioxide, a toxic white powder, arsenic glass was also produced. Handling the powdery poison was very difficult. The workers were only sent into the chimneys to sweep the arsenic with a damp cloth in front of their faces - without a special bonus, hardly any worker was willing to sweep the arsenic dust. A contemporary report by master smelter, Seidensticker, stated that, "the arsenic trioxide produced cannot be weighed because this would cause disproportionately high costs and endanger workers' health more than the rest of the arsenic work put together."

Bad Lauterberg is a town in the district of Göttingen, in Lower Saxony, Germany. It is situated in the southern Harz, approx. 15 km southwest of Braunlage, and 20 km southeast of Osterode am Harz. Bad Lauterberg is known inter alia for the liqueurs, Schierker Feuerstein and Harzer Grubenlicht, which are both manufactured and bottled here. Bad Lauterberg was the birthplace (1879) of the Polar explorer Alfred Ritscher.

The Koboltstaler Köpfe ("Kobolt Valley Peaks") are a group of three mountains, that rise southwest of Sankt Andreasberg and east of Sieber in the district of Göttingen in Lower Saxony. The highest of the three peaks is 673 metres high. The other two summits lie roughly 350 metres east and south of the main peak respectively and are ony a few metres lower. The Koboltstaler Köpfe are mainly covered by pine forest and accessible on all sides by forest roads. To the southwest runs a mountain ridge, the Gödeckenkopf or Gödeckekopf, whose crest lies between 600 and 650 metres high. It is bounded to the west by the Mittleren Gödeckental and to the east by the Kleinen Gödeckental. To the southwest it falls away steeply towards the Großes Gödeckental valley.

The Grade Lutter is a river of Lower Saxony, Germany. It is one of the two headstreams of the River Lutter in the South Harz. It rises at over 660 metres on the Aschentalshalbe. It then flows mainly in a southerly direction in order to merge with the Krumme Lutter near the district Kupferhütte of Bad Lauterberg to form the Lutter.

The Grünhirscher Stollen (also Grünhirschler Stollen or Grüne Hirschler Stollen, German: Green Stag's Adit) is an adit (German: Wasserlösungsstollen) for water drainage in Sankt Andreasberg, in the Harz mountains. It was created during mining in the Upper Harz and named after the valley Grüner Hirsch (German: Green Stag) between the mountains Galgenberg and Glockenberg. It leads from the Samson Pit to the south-west of the Galgenberg.The first 7.1 km of the 10.2 km adit is part of the Upper Harz Water Regale and has been declared UNESCO World Heritage Site.

Heibeek is a small river of Lower Saxony, Germany. It flows into the Lutter near Bad Lauterberg.

Sankt Andreasberg is a former town in the district of Goslar, in Lower Saxony, Germany. Since 1 November 2011, it is part of the town Braunlage. It is situated in the Harz, approximately 7 km west of Braunlage proper, and 20 km east of Osterode am Harz.
