Valley Of The Lakes
The Valley of the Lakes ( mn, Нууруудын хөндий) is an intermontane depression located in southwestern Mongolia, separating the Khangai and Govi-Altai mountains. The valley stretches 500 km long, has a width of approximately 100 km, and is located at altitudes ranging between 1000 and 1400 meters above sea level. The topography is dominated by sandy and rocky plains, with solonchak and takir soils present. Along the valley floor lies a chain of large and small saline lakes, which are generally shallow, with a saucer-shaped depth profile. The largest of these lakes are Böön Tsagaan Lake and Orog Lake. Water levels vary considerably in size both seasonally and from year to year, and some lakes may dry out completely in certain years. They all receive their inflow from rivers which rise in the Khangai Mountains, and no permanent inflow comes from the Gobi-Altai. Barchan sand dunes are located on the valley's margins. The region near the Govi-Altai is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayankhongor Province
The Bayankhongor Province or Bayanhongor Aimag, , "Rich Darling Province" is one of the 21 aimags (provinces) of Mongolia. It is located in the southwest of the country and, at 116,000 square kilometers, it is one of the largest aimags. The capital of the aimag shares the provincial name, Bayankhongor. History Bayankhongor aimag was formed in 1941 with the establishment of the Bayankhongor Citizen's Assembly. There were originally 16 Bayankhongor Area Soums and about 41 thousand people in the aimag. The aimag was originally named ''Govi-Bumbugur'', however it was soon changed to Bayankhongor. In April 1976, Bayankhongor was awarded the Outstanding Red Award for livestock, meat, and wool production. The aimag received substantial investment from the former USSR, including infrastructure and education. However, the USSR also systematically repressed the religion and cultural heritage of the aimag, purging famous monasteries such as the Geegin Monastery and killing thousands of mo ...

Barchan
A barchan or barkhan dune (from Kazakh бархан ) is a crescent-shaped dune. The term was introduced in 1881 by Russian naturalist Alexander von Middendorf, based on their occurrence in Turkestan and other inland desert regions. Barchans face the wind, appearing convex and are produced by wind action predominantly from one direction. They are a very common landform in sandy deserts all over the world and are arc-shaped, markedly asymmetrical in cross section, with a gentle slope facing toward the wind sand ridge, comprising well-sorted sand. This type of dune possesses two "horns" that face downwind, with the steeper slope known as the slip face, facing away from the wind, downwind, at the angle of repose of the sand in question, approximately 30–35 degrees for medium-fine dry sand. The upwind side is packed by the wind, and stands at about 15 degrees. Barchans may be high and wide at the base measured perpendicular to the wind. Simple barchan dunes may appear ...

Gobi Lakes Valley Desert Steppe
The Gobi Lakes Valley desert steppe ecoregion (WWF ID: PA1315) covers the narrow, flat valley in southwestern Mongolia that lies between the Khangai Mountains (to the north), and the Gobi-Altai Mountains (to the south). The region is known as the " Valley of the Lakes" because runoff from the mountains collect in lakes that have no outlet to the sea. Although the valley is a semi-arid desert steppe, it has areas of wetlands near the lakes that are important habit for water birds. Location and description The Gobi Lakes Valley is about 500 km west-to-east, and 150 km north-to south, at elevations of 1,000-1,400 meters. The region is desert steppe, with rivers from the Khangai Mountains on the north providing most of the water to the lakes. On the south the region is bounded by the Gobi-Altai range, the easternmost extension of the Altai. A chain of shallow, saline lakes include Böön Tsagaan Lake (Lake Buuntsaagan), Taatsiin Tsagaan Lake, Adgiin Tsagaan Nuur, and La ...

Nikolay Przhevalsky
Nikolay Mikhaylovich Przhevalsky (or Prjevalsky;; pl, Nikołaj Przewalski, . – ) was a Russian geographer of Polish descent (he was born in a Polish noble family), and a renowned explorer of Central and East Asia. Although he never reached his ultimate goal, the holy city of Lhasa in Tibet, he traveled through regions then unknown to the West, such as northern Tibet (modern Tibet Autonomous Region), Amdo (now Qinghai) and Dzungaria (now northern Xinjiang). He contributed substantially to European knowledge of Central Asian geography. He also described several species previously unknown to European science: Przewalski's horse, Przewalski's gazelle, and the wild Bactrian camel, all of which are now endangered. He was a mentor of his follower Pyotr Kozlov. Biography Przhevalsky was born in Kimborovo, in the Smolensky Uyezd of the Smolensk Governorate of the Russian Empire in the Polish noble family. He studied there and at the military academy in St. Petersburg. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Shorebirds
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Anatidae
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant s ...

1957 Mongolia Earthquake
An earthquake occurred in southern Mongolia on December 4, 1957, measuring 7.8–8.1 and assigned XII (''Extreme'') on the Modified Mercalli intensity scale. Surface faulting was observed in the aftermath with peak vertical and horizontal scarp reaching . Because of the extremely sparse population in the area, this event, despite its magnitude, was not catastrophic. However, 30 people died and the towns of Dzun Bogd, Bayan-leg and Baruin Bogd were completely destroyed. Tectonic setting As the Indian Plate collides with the Eurasian Plate, the force of the collision causes deformation. A primary effect of this collision is the uplift of the Himalayas; however, deformation extends further. In Mongolia, escape tectonics created a network of active faults to support the strike-slip stresses. During this earthquake, two main faults sustained a rupture: the thrust Gurvan Bulag fault, and the related strike-slip Bogd fault. The Gurvan Bulag has a slip rate of /yr for the vertica ...

Khangai Mountains
The Khangai Mountains ( mn, Хангайн нуруу, Hangain nuruu, ); form a mountain range, range in central Mongolia, some west of Ulaanbaatar. Name Two provinces of Mongolia are named after the Khangai mountains: Arkhangai (North Khangai) and Ovorkhangai (South Khangai). The mild climate area where the two provinces meet (in eastern Khangai) is known as the cradle of Mongolian and nomadic civilization. The plains at the foot of the eastern Khangai host the Orkhon Valley, Orkhon Valley World Heritage Site. The Xiongnu capital Luut Khot (Lungcheng), the Xianbei state, Xianbei capital Ordo and the Rouran capital Moomt (Mume) are said to have been located there. Later empires also established their capitals there: e.g. the Uyghur Khaganate (745–840) built their capital Ordu-Baliq in the region. Features The tallest mountain is Otgontenger ( "Youngest sky"), which is about 4,000 metres tall. It is revered by the Mongols and state ceremonies are held there. Suvraga Khairkha ...
