Through Russia, Russians and Western Hemisphere

Chukotka is primarily populated by ethnic Russians, Chukchi, and other indigenous peoples. It is the only autonomous okrug in Russia that is not included in, or subordinate to, another federal subject, having separated from Magadan Oblast in 1992. It is home to Lake Elgygytgyn, an impact crater lake, and Anyuyskiy, an extinct volcano. The village of Uelen is the easternmost settlement in Asia and the closest substantial settlement in Russia to the United States (Alaska).

The autonomous okrug covers an area of over 737,700 square kilometers (284,800 sq mi), and is the seventh-largest federal subject in Russia. However, it has a population of only 50,526. Chukotka is the second-least-populated federal subject, and the least densely populated federal subject in Russia. The region is the northeasternmost region of Russia, and since the sale of Alaska in 1867, it has been the only part of Russia lying partially in the Western Hemisphere.

Geography

Chukotka is bordered in the north by the Chukchi Sea and the East Siberian Sea, which are part of the Arctic Ocean; in the east by the Bering Strait and the Bering Sea, part of the Pacific Ocean; in the south by Kamchatka Krai and Magadan Oblast; and in the west by the Sakha Republic. The Chukchi Peninsula projects eastward forming the Bering Strait between Siberia and the Alaska Peninsula, and encloses the north side of the Gulf of Anadyr. The peninsula's easternmost point, Cape Dezhnev, is also the easternmost point of mainland Russia. While most of Russia is on the Eurasian plate, Chukotka sits on the North American plate.

Ecologically, Chukotka can be divided into three distinct areas: the northern Arctic desert, the central tundra, and the taiga in the south. About half of its area is above the Arctic Circle. This area is very mountainous, containing the Chukotsky Mountains (highest point Iskhodnaya) and the Anadyr Highlands.

Chukotka's rivers spring from its northern and central mountains. The major rivers are:

  • Anadyr River, with tributaries Belaya, Tanyurer, Yablon, Yeropol, Mayn and Velikaya rivers, as well as the Avtatkuul River, which flows across the Anadyr Lowlands into the Gulf of Anadyr.
  • Omolon and the Great and Little Anyuy Rivers flow west into the Kolyma River in Yakutia (Sakha).
  • Rauchua, Chaun, Palyavaam, Pegtymel, Chegitun and Amguyema Rivers that flow north into the arctic seas.

The largest lakes are Lake Krasnoye, west of Anadyr, Lake Pekulney and Lake Elgygytgyn in central Chukotka. Other important lakes are Koolen, Lake Ioni, Pychgynmygytgyn, Medvezhye, Achchyon and Maynits.

The okrug's extensive coastline has several peninsulas, the main ones being the Kyttyk Peninsula, Cape Shelagsky, the Aachim Peninsula, the Chukchi Peninsula and Russkaya Koshka.

There are also several islands belonging to Chukotka, from west to east the main ones being Ayon Island, Ryyanranot Island, Chengkuul Island, Mosey Island, the Routan Islands, Shalaurov Island, Wrangel Island, Herald Island, Kosa Dvukh Pilotov Island, Karkarpko Island, Kolyuchin Island, Serykh Gusey Islands, Idlidlya Island, Big Diomede Island, Ilir Island, Arakamchechen Island, Yttygran Island, Merokinkan Island, Achinkinkan Island and Kosa Meechkyn Island.

Large parts of Chukotka are covered with moss, lichen, and arctic plants, similar to western Alaska. Surrounding the Gulf of Anadyr and in the river valleys grow small larch, pine, birch, poplar, and willow trees. More than 900 species of plants grow in Chukotka, including 400 species of moss and lichen. It is home to 220 bird species and 30 fresh water fish species.

Climate

Chukotka's climate is influenced by its location on the three neighboring seas: the Bering Sea, the East Siberian Sea, and the Chukchi Sea with its weather characterized by cold northerly winds that can quickly change to wet southern winds. Cape Navarin has the highest number of hurricanes and storms in Russia. The coastal areas are windy with little precipitation, between 200 and 400 mm (7.9 and 15.7 in) per year. Temperature varies between −45 and −15 °C (−49 and 5 °F) in January, and between +5 and +14 °C (41 and 57 °F) in July. Growing season is short, lasting only 80 to 100 days per year.
