27-703: The district is named after the two main regions. The Teltow is an agricultural belt south of Berlin . The Fläming is a wooded hill chain in the south; the portion located in this district is called the Lower Fläming, while the Higher Fläming is situated in Potsdam-Mittelmark . The district was formed in December 1993 by merging the previous districts Luckenwalde, Jüterbog and Zossen, but also including small parts from other former districts such as Luckau . In

54-419: A salt dome . Because all the readily soluble salts have been leached out, only a solution residue has been left on the surface of the gypsum. Rock salt is only found at a depth of 45 m (148 ft) (about 0 metres (0 ft) above NN). The gypsum hill is also of historic scientific interest, because it was here, in 1867, that the first borehole in the world to reach a depth of 1,000 metres (3,300 ft)

81-611: A sandur and a terminal moraine . Urstromtäler of Central Europe (Poland, Germany and Denmark especially) were directly connected to the North Atlantic Ocean, via the Channel River , during Pleistocene maximum glaciations, i.e. at times of confluence of the British and Fennoscandian ice-sheets in the intervening North Sea. Urstromtäler should not be confused with tunnel valleys . The latter are formed beneath, not in front of,

108-838: The Elbe–Havel Canal or the Oder–Havel Canal . Because the land in North America and on the Russian Plain tilts towards the south, the formation of Urstromtäler there during the ice age did not take place. The Mississippi River and its tributaries carried the meltwaters of the North American ice sheet away. In Eastern Europe the meltwaters flowed down the river basins of the Dnieper , Don and Volga . Urstromtäler , whether sandy or boggy, posed considerable obstacles to movement in

135-542: The March of Brandenburg was formed in the 12th and 13th centuries. As a result of the Teltow War  [ de ] (1239–1245) the question of territorial lordship of the newly created heart of the expanding march was finally decided here. Between 1835 and 1952 there was also a county, Teltow district  [ de ] ; in addition a town immediately south of Berlin, in the present-day county of Potsdam-Mittelmark , bears

162-569: The ice ages , or individual glacial periods of an ice age, at the edge of the Scandinavian ice sheet and was formed by meltwaters that flowed more or less parallel to the ice margin. Urstromtäler are an element of the glacial series . The term is German and means "ancient stream valley". Although often translated as "glacial valley", it should not be confused with a valley carved out by a glacier. More accurately some sources call them "meltwater valleys" or "ice-marginal valleys". Important for

189-697: The Aller Urstromtal are parts of the Breslau-Magdeburg-Bremen Urstromtal . The Baruth, Berlin and Eberswalde Urstromtäler are common short names for the associated sections of the Urstromtal in Brandenburg . In addition to the large main valleys there are also numerous smaller meltwater valleys ( Urstromtalungen ). Their appearance is similar to that of the great Urstromtäler , but they are considerably shorter. They are also not linked to

As an historical region, the Teltow was one of the eight territories out of which

243-594: The Brandenburg stage of Weichsel glaciation . The Weichsel ice sheet pushed southwards right over the Teltow before reaching the northern edge of the Baruth Urstromtal, the limit of its expansion to the south. Terminal moraines can be found there, for example, around Dobbrikow in Luckenwalde (Weinberg) and near Sperenberg . However, the line of terminal moraines is very patchy and is traces out an ice front . To

270-507: The building materials industry. But they only outcrop at a small sand pit at Lindenberg near Jühnsdorf . The old Elbe strata are overlain by the very thick (40 metres or more) sediments of the Saale ice age . These are usually the depositions of proglacial lakes or glacial till . At several points they even break through the Weichselian deposits and are immediately on, or at least very close to,

297-445: The coat of arms of the family of Torgow, who owned the area around Zossen until 1478. After the creation of the new district a public contest was held to create a coat of arms for the district. Out of ten proposals the parliament of the district selected the one made by the designer Horst Nehls from Merow. The coat of arms were officially granted by ministry of interior of Brandenburg on November 21, 1996. 1. Dahme/Mark seat of

324-726: The cultural landscape is general seen as the Baruth Urstromtal . Further south is the heathland of the Fläming . The Havel river separates the Teltow from the Nauen Plateau to the northwest. The Nuthe- Nieplitz Lowland, an urstromtal feature, separates it from the sander plateau of the Zauche in the southwest and the Berlin Urstromtal forms the boundary with the Barnim Plateau in

351-760: The deeply buried sediments of the Elster Ice Age have virtually no impact on the current appearance of the Teltow, the subsurface, sandy, gravelly sediments of the so-called Berlin Elbe course occur over a wide area. These deposits formed between the Elster and Saalian ice advances, when the Elbe flowed northwards from the location of present-day Torgau and crossed the area of the Fläming which did not yet exist. These sediments are of great economic importance, both as groundwater conduits and for

378-416: The district of Dahme-Spreewald . The coat of arms show the eagle of Brandenburg to the left, as the margraves of Brandenburg began to rule the northern and northwestern part of the district in the 13th century. To the right is a staff of an abbot. It symbolizes the clerical state of Magdeburg , to which the southern and middle part of the district belonged. The black-and-white checkered bottom derives from

405-642: The earth's surface (for example, in Glienick near Zossen ). Because the Saale ice shoved the underlying sediments strongly, Tertiary deposits are found at the surface in places. For example, in Schenkendorf near Königs-Wusterhausen in the second half of the 19th and the first half of the 20th century, brown coal was extracted. Today's Teltow plateau in Brandenburg-Berlin was formed around 20,000 years ago during

432-530: The east the borders are formed by the rivers Dahme , as well by the Havel and Nuthe to the west. To the southwest, the countryside around the Pfefferfließ is also counted as part of the Teltow, although it has no clear boundaries. The regional border in the south is unclear, because the ground moraines here were often eroded by urstromtal processes. For example, there are many small island plateaux. The boundary of

459-476: The eastern boundary of the Teltow the Müggelberge are neither part of the Teltow geologically nor from a cultural landscape perspective. One geological feature is the 80-metre (260 ft) high Sperenberg hill on the northern rim of the Baruth Urstromtal. Uniquely for Brandenburg, the hill is made of gypsum . The rising column of Zechstein -age salt has pushed through all the more recent deposits here to form

486-484: The edges of an Urstromtal may have been significantly altered by more recent processes, especially the thawing of dead ice blocks or the accumulation of sand dunes . In the post-glacial period , many Urstromtäler became bogs due to their low lying situation and the high water table. In Central Europe , there are several Urstromtäler from various periods. Some sections of the aforementioned main valleys have been given their own names. The Lusatian Urstromtal and

513-617: The emergence of the Urstromtäler is the fact that the general lie of the land on the North German Plain and in Poland slopes down from south to north. Thus the ice sheet that advanced from Scandinavia flowed into a rising terrain. The meltwaters could therefore only flow for a short distance southwards over the sandurs (outwash plains) before having to find a way to the North Sea basin that

540-430: The grain size can vary considerably, however. Fine sand dominates especially in the upper sections of the Urstromtal sediments. The thickness of the Urstromtal sediments also varies a great deal, but is mostly well over ten metres. Urstromtäler have wide and very flat valley bottoms that are between 1.5 and 20 kilometres wide. The valley sides, by contrast are only a few to a few dozen metres high. The bottom and

567-456: The ice mass. In addition most tunnel valleys run from north to south. The principal direction of Urstromtäler is from east to west. Today Urstromtäler are only partly used by rivers, because the majority have found shorter routes to the sea (like the Oder and Vistula ). The straight troughs of the Urstromtäler between the rivers were used for canal routes due to their low gradient, for example for

594-559: The name Teltow . The Teltow is not a unified region, either from a historical or a landscape perspective. The present-day term is defined by an ice age plateau that consists mainly of ground moraine elements. Its natural northern border is defined by the range of the Tempelhofer Berge, among them the Kreuzberg rising to 66 m (217 ft), along the southern bank of the Spree . To

Only south of Ludwigsfelde , does the contiguous ground moraine plateau of the Teltow begin. 52°22′00″N 13°20′00″E  /  52.3666667°N 13.3333333°E  / 52.3666667; 13.3333333 Urstromtal An urstromtal (plural: Urstromtäler ) is a type of broad glacial valley , for example, in northern Central Europe , that appeared during

648-569: The northeast. It is, however, disputed whether the Müggelberge hills, which are up to 115 m (377 ft) above sea level (NN) , in southeast Berlin are part of the Teltow. From a geological standpoint they certainly are, because the hills have a similar development history. However, these upland remnants are completely isolated within the Berlin Urstromtal. If the River Dahme is taken as

[1] Flaeming-Skate is a 160 km (99 mi) long route specially for inline skating , the only such route in Germany. Curiously, the town of Teltow is not a part of the district Teltow-Fläming, just as the town of Dahme is not a part of

702-504: Was drilled. The geothermal gradient was found to be about 3  K /100 metres; this was also a first. Sperenberg gypsum was mined from the Middle Ages to 1957 in several quarries. Other salt domes, which do not quite reach the surface, occur under Mittenwalde and the Blankensee lake. For the geological structure of the Teltow, they are of secondary significance, however. While

729-465: Was parallel to the ice margin. At that time, the area that is now the North Sea was dry as a result of the low level of the sea. As elements of the glacial series, Urstromtäler are intermeshed with sandur areas for long stretches along their northern perimeters. It was over these outwash plains that the meltwaters poured into them. Urstromtäler are relatively uniformly composed of sands and gravels ;
