Strohner Maar
The Strohner Maarchen (also Strohner Märchen) is a dry maar near the village of Strohn in the Volcanic Eifel region of Germany. Its bowl forms an elongated oval and has a diameter of about 210 x 140 metres. Its name ("maarchen" means "little maar") stems from the fact that it is small for a maar. Together with the Pulvermaar to the north and the adjacent hill of Römerberg the Strohner Maarchen lies within the nature reserve of Pulvermaar mit Römerberg und Strohner Märchen. Vulcanologists from the Smithsonian Institution The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge".

Dürres Maar
__NOTOC__ The Dürres Maar is a maar located in the vicinity of the village of Gillenfeld, Germany in the West Eifel mountains about 400 metres northwest of the Holzmaar. The Dürres Maar ist a dry maar, the original maar lake has silted up. It is surrounded by an embankment of lapilli-tuff which has only been gently eroded and has a diameter of about 290 metres. The Dürres Maar was formed more than 25,000 years ago. In the hollow formed by the maar is a transitional bog, which is made of sphagnum and brown moss peats. The peat body is about 3,000 to 4,000 years old and has a thickness of about 12 metres. Below the peat are heavily disintegrated limnic deposits that date to the late late glacial period. The bog is not only fed by precipitation, but also be springs that are found at the northeastern end. The Dürres Maar is protected as a nature reserve A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserv ...

Holzmaar
The Holzmaar lies in the Volcanic Eifel in the German state of Rhineland-Palatinate almost halfway between Gillenfeld (2.5 km away to the southwest) and Eckfeld. The maar has an area of about , a diameter of and a depth of and lies within a nature reserve, almost completely surrounded by woods. It is one of the two maars making up the Gillenfeld Maars, the other being the Pulvermaar. The Holzmaar is fed by a headstream of the Sammetbach which crosses the maar. In the immediate vicinity is another maar, the Dürres Maar. On its south and southwest shores, the maar has silted up with sediments, core samples from which give a comprehensive picture of the climate going back to the last cold period. The sediments of the Holzmaar go back 23,200 years. This assessment was made possible by comparing the sequence and radiometric dating obtained in the maar basin with that of the Meerfelder Maar. The time of the maximum of the last glaciation derived from varve chronology is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''

Strohn
Strohn is an ''Ortsgemeinde'' – a municipality belonging to a ''Verbandsgemeinde'', a kind of collective municipality – in the Vulkaneifel district in Rhineland-Palatinate, Germany. It belongs to the ''Verbandsgemeinde'' of Daun, whose seat is in the like-named town. Geography Location The municipality lies in the Vulkaneifel, a part of the Eifel known for its volcanic history, geographical and geological features, and even ongoing activity today, including gases that sometimes well up from the earth. Strohn lies south of Gillenfeld and the Pulvermaar, a local volcanic crater lake, on the river Alf’s left bank. Constituent communities The following hamlets and homesteads belong to Strohn: Altheck, Buchholz, Dornheck, Herrenbüsch, Sprink, Tannenhof and Trautzberg.

Volcanic Eifel
The Volcanic Eifel or Vulkan Eifel (german: Vulkaneifel) is a region in the Eifel Mountains in Germany that is defined to a large extent by its volcanic geological history. Characteristic of this volcanic field are its typical explosion crater lakes or maars, and numerous other signs of volcanic activity such as volcanic tuffs, lava streams and volcanic craters like the Laacher See. The Volcanic Eifel is still volcanically active today. One sign of this activity is the escaping gases in the Laacher See. Geographical location The Volcanic Eifel stretches from the Rhine to the Wittlich Depression. It is bordered in the south and southwest by the South Eifel, in the west by Luxembourg and Belgian Ardennes and in the north by the North Eifel including the Hohes Venn. To the east the Rhine forms its geographical boundary, with no volcanicity immediately beyond it. The Volcanic Eifel is divided into three natural regions: * Volcanic West Eifel ( Manderscheid, Daun, Gerolstein, Ober ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pulvermaar
The Pulvermaar is a water-filled maar that lies southeast of Daun in the German state of Rhineland-Palatinate. Together with the Holzmaar it is one of the Gillenfeld maars. Description A tuff site in the bog formations of the neighbouring Strohner Maar is ascribed to the Pulvermaar and is therefore older than the Pulvermaar. Early pollen analyses of the bogs gave an age for the tuff site – and thus the Pulvermaar – of about 10,050 years. More recent studies show, however, underwater terraces at greater depth as well as ice wedges inside the tephra deposits, both of which suggest that the maar was formed during the last ice age, 20,000 to 30,000 years ago. Vulcanologists from the Smithsonian Institution estimate the last eruption of the Strohner Maar and Pulvermaar in 8,300 BC. The almost circular maar has steep funnel-shaped sides. The maar lake lies at a height of and, with a maximum depth of , is the deepest in the Volcanic Eifel. It has a diameter of about and surface ...

Naturschutzgebiet
A ''Naturschutzgebiet'' (abbreviated NSG) is a category of protected area (nature reserve) within Germany's Federal Nature Conservation Act (the ''Bundesnaturschutzgesetz'' or ''BNatSchG''). Although often translated as 'Nature Reserve' in English, the Federal Agency for Nature Conservation (BfN) refers to them as 'Nature Conservation Areas'. It meets the criteria of an IUCN Category IV Habitat and Species Management Area.https://www.bfn.de/fileadmin/MDB/documents/themen/gebietsschutz/IUCN_Kat_Schutzgeb_Richtl_web.pdf Document of the Federal Agency for Nature Conservation of Germany Points of law The use of the term ''Naturschutzgebiet'' or terms that could be confused with it for anything other than the legally protected areas is forbidden under this law. Signage Because legal restrictions are placed on activity within German nature reserves they have to be signed on the ground. Only by this means can e.g. walkers know that they are entering a nature reserve and may not e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bogs Of Rhineland-Palatinate
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall'. Retrieved 7 July 2020 They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. In contrast to fens, they derive most of th ...
