Anadyr Highlands
The Anadyr Highlands ( rus, Анадырское нагорье, r=Anadyrskoye Nagorye) are a mountainous area in the Chukotka Autonomous Okrug, Far Eastern Federal District, Russia. Geography The Anadyr Highlands are one of the two main mountain regions of Chukotka Autonomous Okrug. They rise southwest of the Chukotka Mountains, in the western Chukotka region. Medium height mountain ranges stretch in roughly WNW/ESE direction west of a large plateau and in a SW/NE direction in the south. The highlands rise between the Chaun Lowlands in the north, the Anadyr Lowlands in the southeast, the Kolyma Mountains in the southwest and the Kolyma Lowlands, where the Kolyma River flows, in the west.Google Earth Among the rivers that have their source in the mountains, the main ones are the Anadyr River flowing off the highland limits to the southeast as the Belaya, the Bolshoy Anyuy and the Maly Anyuy —flowing westwards on both sides of the Anyuy Range. The Enmyvaam flows southwards ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Elgygytgyn
Lake El'gygytgyn (Russian and Chukchi: Эльгыгытгын) is an impact crater lake located in the Chukotka Autonomous Okrug in northeast Siberia, about southeast of Chaunskaya Bay. The word "Elgygytgyn" means "white lake" in the Chukchi language. The lake is of particular interest to scientists because it has never been covered by glaciers. This has allowed the uninterrupted build-up of of sediment at the bottom of the lake, recording information on prehistoric climate change. Geography Lake El'gygytgyn is located in the Anadyr Plateau, part of the Anadyr Highlands. It is drained to the southeast by the Enmyvaam, a tributary of the Belaya. It is approximately in diameter and has a maximum depth of . The lake is centered within an impact crater with a rim diameter of that formed 3.6 million years ago during the Pliocene. Before it was reliably dated, preliminary papers in the late 1970s suggested either Elgygytgyn or Zhamanshin as the source of the young Austra ...

Kolyma River
The Kolyma ( rus, Колыма, p=kəlɨˈma; sah, Халыма, translit=Khalyma) is a river in northeastern Siberia, whose basin covers parts of the Sakha Republic, Chukotka Autonomous Okrug, and Magadan Oblast of Russia. The Kolyma is frozen to depths of several metres for about 250 days each year, becoming free of ice only in early June, until October. Course The Kolyma begins at the confluence of the Kulu and the Ayan-Yuryakh, originating in the Khalkan Range and flows across the Upper Kolyma Highlands in its upper course. Leaving the mountainous areas it flows roughly northwards across the Kolyma Lowland, a vast plain dotted with thousands of lakes, part of the greater East Siberian Lowland. The river empties into the Kolyma Gulf of the East Siberian Sea, a division of the Arctic Ocean. The Kolyma is long. The area of its basin is . The average discharge at Kolymskoye is , with a high of reported in June 1985, and a low of in April 1979. Tributaries The m ...

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, o ...

Chaun River
The Chaun (russian: Чаун) is a stream in Far East Siberia. It flows roughly northwards, passing through the sparsely populated areas of the Siberian tundra. It is long, and has a drainage basin of . Course The Chaun originates in rivers flowing from the Ilirney Range and the northwestern edge of the crater of Lake Elgygytgyn (Maly Chaun). After joining they flow into the East Siberian Sea at Chaun Bay, south of the port town Pevek. The river Palyavaam discharges into a right distributary of the Chaun. Its most important tributaries are the Ugatkyn from the left side and the Milguveyem from its right side. The Chaun river gives the Chaun Bay its name.
