About Kolyma

The Kolyma (Russian: Колыма, IPA: [kəlɨˈma]; Yakut: Халыма, romanized: Xalıma) 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.

Kolyma in Depth

Course

The Kolyma begins at the confluence of the Kulu and the Ayan-Yuryakh (the Kolyma a natural continuation of Ayan-Yuryakh). The confluence happens in the Okhotsk-Kolyma Upland (Охотско-Колымское нагорье), which lies within the watershed that separates the Kolyma basin and the basins of rivers flowing into the Sea of Okhotsk. Kolyma flows across the Upper Kolyma Highlands roughly southwards 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 2,129 kilometres (1,323 mi) long. The area of its basin is 647,000 square kilometres (250,000 mi2).

History

In 1640 Dimitry Zyryan (also called Yarilo or Yerilo) went overland to the Indigirka. In 1641 he sailed down the Indigirka, went east and up the Alazeya. Here they heard of the Kolyma and met Chukchis for the first time. In 1643 he returned to the Indigirka, sent his yasak (tribute) to Yakutsk and went back to the Alazeya. In 1645 he returned to the Lena where he met a party and learned that he had been appointed prikazchik (land administrator) of the Kolyma. He returned east and died in early 1646. In the winter of 1641–42 Mikhail Stadukhin, accompanied by Semyon Dezhnyov, went overland to the upper Indigirka. He spent the next winter there, built boats and sailed down the Indigirka and east to the Alazeya where he met Zyryan.
