Karst Lake
Karst lakes are formed as the result of a collapse of caves, especially in water-soluble rocks such as limestone, gypsum and dolomite. This process is known as karstification. They can cover areas of several 100 square kilometres. Their shallow lakebed is usually an insoluble layer of sediment so that water is impounded, leading to the formation of lakes. Many karst lakes only exist periodically, but return regularly after heavy rainfall. Distribution Karst lakes are found in the area around the Harz Mountains of Germany (e. g. the Juessee and the Bauerngraben in the South Harz Karst Landscape Biosphere Reserve, an episodic karst lake on the Karst Trail), in South Germany (e.g. the Eichener See), in France in the region of Quercy, in Estonia the Tudre and the region of Salajõe, in Slovenia (e. g. the Cerkniško jezero), in Montenegro and Albania (e.g., Lake Skadar), in Ireland the so-called turloughs (there is also a turlough in Wales: Pant-y-llyn near Llandeilo) ...

Cerkniško Jezero
Lake Cerknica (; sl, Cerkniško jezero, german: Zirknitzer See) is an intermittent lake in the southern part of the Cerknica Polje, a karst polje in Inner Carniola, a region in southwestern Slovenia. The lake, oriented in the Dinaric direction from northwest to southeast, is present for the most part of the year. When full, it is the largest lake in the country. The plain is surrounded by the Javornik Hills () to the south and Slivnica () to the north, both belonging to Dinaric Alps. The area of the lake mainly reaches , but can reach up to and the surface level varies from to above sea level. The lake is an important wildlife resort, especially as a nesting place for many bird species. Botanically, it is distinguished by amphibious plants. It is therefore a part of two Natura 2000 areas of protection and the focus of the Inner Carniola Regional Park, which covers additional Natura 2000 areas in the broader region. The climate in the area is continental, with a mean temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chichen Itza
Chichen Itza , es, Chichén Itzá , often with the emphasis reversed in English to ; from yua, Chiʼchʼèen Ìitshaʼ () "at the mouth of the well of the Itza people" was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archeological site is located in Tinúm Municipality, Yucatán State, Mexico. Chichen Itza was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the Northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural ...

Cenote Sagrado
The Sacred Cenote ( es, cenote sagrado, , "sacred well"; alternatively known as the "Well of Sacrifice") is a water-filled sinkhole in limestone at the pre-Columbian Maya archaeological site of Chichen Itza, in the northern Yucatán Peninsula. It is located to the north of Chichen Itza's civic precinct, to which it is connected by a ''sacbe'', a raised pathway. According to both Maya and Spanish post-Conquest sources, pre-Columbian Maya deposited valuables and human bodies into the cenote as a form of sacrifice to the rain god Chaac. Edward Herbert Thompson dredged the Cenote Sagrado from 1904 to 1910, and recovered artifacts of gold, jade, pottery, and incense, as well as human remains. Beginning in the 1950s several Mexican-driven projects were conducted in the cenote, including a 1961 project that used an airlift dredge. Description and history The northwestern Yucatán Peninsula is a limestone plain, with no rivers or streams, lakes or ponds. The region is pockmarked w ...

Mayans
The Maya peoples () are an ethnolinguistic group of indigenous peoples of Mesoamerica. The ancient Maya civilization was formed by members of this group, and today's Maya are generally descended from people who lived within that historical region. Today they inhabit southern Mexico, Guatemala, Belize, El Salvador, and Honduras. "Maya" is a modern collective term for the peoples of the region, however, the term was not historically used by the indigenous populations themselves. There was no common sense of identity or political unity among the distinct populations, societies and ethnic groups because they each had their own particular traditions, cultures and historical identity. It is estimated that seven million Maya were living in this area at the start of the 21st century. Guatemala, southern Mexico and the Yucatán Peninsula, Belize, El Salvador, and western Honduras have managed to maintain numerous remnants of their ancient cultural heritage. Some are quite integrated int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yucatán (peninsula)
Yucatán (, also , , ; yua, Yúukatan ), officially the Free and Sovereign State of Yucatán,; yua, link=no, Xóot' Noj Lu'umil Yúukatan. is one of the 31 states which comprise the federal entities of Mexico. It comprises 106 separate municipalities, and its capital city is Mérida. It is located on the northern part of the Yucatán Peninsula. It is bordered by the states of Campeche to the southwest and Quintana Roo to the southeast, with the Gulf of Mexico off its northern coast. Before the arrival of Spaniards in the Yucatán Peninsula, the name of this region was ''Mayab''. In the Yucatec Maya language, ''mayab'' means "flat", and is the source of the word "Maya" itself. The peninsula was a very important region for the Maya civilization, which reached the peak of its development here, where the Mayans founded the cities of Chichen Itza, Izamal, Motul, Mayapan, Ek' Balam and Ichcaanzihóo (also called Ti'ho), now Mérida. After the Spanish conquest of Yucatán (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenote
A cenote ( or ; ) is a natural pit, or sinkhole, resulting from the collapse of limestone bedrock that exposes groundwater. The regional term is specifically associated with the Yucatán Peninsula of Mexico, where cenotes were commonly used for water supplies by the ancient Maya, and occasionally for sacrificial offerings. The term derives from a word used by the lowland Yucatec Maya——to refer to any location with accessible groundwater. Similar rock-sided sinkholes like cenotes are common geological forms in low-altitude regions, particularly on islands, coastlines, and platforms with young post-Paleozoic limestone with little soil development. The term ''cenote'' has also been used to describe similar karst features in other countries such as Cuba and Australia. Definition and description Cenotes are surface connections to subterranean water bodies. While the best-known cenotes are large open-water pools measuring tens of meters in diameter, such as those at Chichen It ...

Andalo
Andalo (''Àndel'' in local dialect) is a ''comune'' (municipality) in Trentino in north Italy, with some 1,200 inhabitants in 2021. It is the seat of the Comunità di Valle dell'Altopiano della Paganella. Geography The town lies on the Paganella plateau, between the mountains Piz Galin, elevation , and Paganella, , and its territory is part of the Adamello-Brenta natural park. History The area was first settled during the Middle Ages, and used to be divided into 13 hamlets called “masi” (Bortolon, Cadin, Casanova, Clamer, Dos, Fovo, Ghezzi, Melchiori, Monech, Pegorar, Perli, Pont and Toscana), which eventually merged into a single town. This fragmentation can still be noticed, especially in the most isolated masi (for instance, maso Pegorar). During the second part of the 20th century the village became one of the most famous touristic resorts in Trentino, mainly due to its skiing facilities. Economy The local economy, once reliant exclusively on agriculture, is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
