Northern Black Forest
The Northern Black Forest (german: Nordschwarzwald) refers to the northern third of the Black Forest in Germany or, less commonly today, to the northern half of this mountain region. Geography The Northern Black Forest is bounded in the north by a line from Karlsruhe to Pforzheim and, in the south, by a line running from the Rench valley to Freudenstadt. Its northern boundary largely coincides with the emergence of the extensively forested bunter sandstone strata from the arable region of the Kraichgau; its southern boundary with the Central Black Forest (or, in the case of a bipartite division, the Southern Black Forest) varies depending on the definition or natural regional division used (see also Black Forest). Earlier, the Northern Black Forest was the entire northern half of the mountain range as far as the Kinzig (Rhine), line of the Kinzig valley, which divides the Black Forest east of Lahr/Schwarzwald, Lahr. To the west it is bounded by the Upper Rhine Plain, to the east ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grinde (landform)
A ''grinde'' (plural: ''grinden'') is an almost treeless area of wet heathland found on the rounded bunter sandstone ridges of the Northern Black Forest in Germany. The ''grinden'' reached their greatest extent in the early 19th century when they ran from the Kniebis mountain near Freudenstadt in the south to the heights near Dobel in the north. Today they are restricted to the highest parts of the Northern Black Forest around the summits of the Hornisgrinde, Schliffkopf and Kniebis (900 to ). They still cover an area of about 180 ha. Conservation measures and careful grazing by robust breeds of cattle (especially the Hinterwald), goats and sheep should enable the remaining ''grinden'' to be preserved for their great ecological value and as an important feature of the landscape. Most of them are under conservation orders. Derivation and meaning of the word The German term ''"Grinde"'' comes from Old High German and is related to the Swabian-Alemannic word ''"Grind"'', which mea ...

Acher
The Acher is a 53.6-kilometre-long river and right-hand tributary of the Rhine in the county of Ortenau, in the south German state of Baden-Württemberg. It flows in an northwesterly direction from the Black Forest to the Rhine, between the two rivers Rench to the south and the Oos to the north. Geography The source region of the Acher lies on the northeastern mountainside of the Vogelskopf () an area divided into cirques formed by the ice age. The spring named the ''Acherquelle'' rises at a height of in the area of the ''Ruhesteinloch'', which is named after the Ruhestein Saddle to the east and is located between the Vogelskopf and Seekopf (). The Acher initially flows northwards, descending steeply. At its confluence with the Seebach, which joins from the north from the Mummelsee below the Hornisgrinde, it turns westwards and flows through the trough-like valley of Seebach. Here the valley reaches a depth of about 550 metres between the Hornisgrinde and the Vogelskopf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alb (Upper Rhine)
The Alb is a river in the Northern Black Forest in Germany. It is a tributary of the Rhine, and flows through the cities of Karlsruhe, Ettlingen and Bad Herrenalb. Geography The river Alb begins about from Bad Herrenalb. From its source it flows north through Bad Herrenalb, Frauenalb and Marxzell. There it takes the waters of the Maisenbach creek as a right tributary. The river Moosalb is a left tributary at Fischweier on the border between the municipalities of Marxzell and Karlsbad. Near Busenbach the Alb turns to the northwest. Out of Ettlingen, the Alb leaves the Black Forest and reaches the Upper Rhine Plain. After flowing through Ettlingen it turns north again. The river passes the Karlsruhe city district of Rüppurr, flows under the Federal Road no. 10 and then follows this highway to the northwest. Afterwards the Alb flows through the so-called Günther Klotz Facilities in the southern part of Karlsruhe – partially being the district border between Bulach and Beier ...

Nagold (river)
The Nagold is a river, 91 kilometres long, in Baden-Württemberg, southwestern Germany. A tributary of the Enz, it gave its name to the town of Nagold. It merges with the smaller Enz in the town centre of Pforzheim. Physical geography General The Nagold is 90.7 kilometres in length and has its source in Urnagold in the municipality of Seewald in the Northern Black Forest and flows in an easterly direction past Nagold, Calw and Liebenzell and joins the Enz in Pforzheim, near what is now the Parkhotel Pforzheim. The Nagold flows mainly through the Black Forest. Around the town of Nagold (between Rohrdorf and Pfrondorf) it flows through the Heckengäu region. At the Pforzheimer Kupferhammer, it enters the Pforzheim Enz Valley, which, like the Heckengäu, also belongs to the natural region of the Gäu. The Nagold is regarded by convention as a tributary of Enz. However, it carries more water than the upper course of the Enz at their confluence, is longer by a factor of about 2 ...

Murg (Northern Black Forest)
The Murg is an 80.2-kilometre-long river (including its headstream, the ''Rechtmurg'') and a right tributary of the Rhine in Baden-Württemberg, Germany. It flows through the Northern Black Forest into the Upper Rhine Plain, crossing the counties of Landkreis Freudenstadt, Freudenstadt and Landkreis Rastatt, Rastatt. Geography Course The Murg valley is one of the largest and deepest valleys in the Black Forest (up to over 700 metres deep) and generally runs in a northerly direction. It separates the precipitation-rich main crest of the Northern Black Forest, including the Hornisgrinde (1,164 m), to the west, from the densely forested bunter sandstone plateaux in the east. The Murg originates from 2 large headstreams in the western part of the municipality of Baiersbronn. Below the Schliffkopf at about , the main headstream of the Right Murg (''Rechtmurg'') is formed by the Schurbach stream and Tränkenteich pond, a little above the ''Murgursprung'' ("Murg Source").

Central Uplands
The Central UplandsDickinson (1964), p.18 ff. (german: die MittelgebirgeN.B. In German die ''Mittelgebirge'' (plural) refers to the Central Uplands; das ''Mittelgebirge'' refers to a low mountain range or upland region (''Mittel'' = "medium" and ''-gebirge'' = "range").) is one of the three major natural regions of Germany. It stretches east to west across the country. To the north lies the North German Plain or Northern Lowland; to the south, the Alps and the Alpine Foreland. Formation The German Central Uplands, like the Scandinavian and British mountain ranges and the Urals, belong to the oldest mountains of Europe, even if their present-day appearance has only developed relatively recently. In the Carboniferous, i.e. about 350 million years ago, Variscan mountain ranges were formed in central Europe by the uplifting caused by tectonic plate collision. Immediately after their formation the erosion of the mountains began under the influence of exogenous processes during the ...

Tor (rock Formation)
A tor, which is also known by geomorphologists as either a castle koppie or kopje, is a large, free-standing rock outcrop that rises abruptly from the surrounding smooth and gentle slopes of a rounded hill summit or ridge crest. In the South West of England, the term is commonly also used for the hills themselves – particularly the high points of Dartmoor in Devon and Bodmin Moor in Cornwall.Ehlen, J. (2004) ''Tor'' in Goudie, A., ed., pp. 1054-1056. ''Encyclopedia of Geomorphology.'' Routledge. London, England. Etymology Although English topographical names often have a Celtic etymology, the Oxford English Dictionary lists no cognates to the Old English word in either the Breton or Cornish languages (the Scottish Gaelic ''tòrr'' is thought to derive from the Old English word). It is therefore accepted that the English word ''Tor'' derives from the Old Welsh word ''tẁrr'' or ''twr'', meaning a cluster or heap. Formation Tors are landforms created by the erosion and weath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porphyries
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective '' porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief character ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...
