Bolshaya Chukochya
The Bolshaya Chukochya or Chukochya (Russian: Большая Чукочья)[1] is a river in the Sakha Republic (Yakutia) of the Russian Federation. It is 758 kilometres (471 mi) long, and has a drainage basin of 19,800 square kilometres (7,600 sq mi).[2] It crosses the tundra roughly northeastwards and flows into the Kolyma Gulf of the East Siberian Sea west of the mouths of the Kolyma. Owing to its extreme northerly location the Bolshaya Chukochya freezes up in early October and remains icebound until June.

The Bolshaya Chukochya basin is located between the basins of the Alazeya and the Kolyma. There are study sites near the Bolshaya Chukochya in order to investigate the mineral transformations in the soils affected by permafrost.[3]
The Bolshaya Chukochya in mainland Eastern Siberia should not be confused with the river Chukochya on Kotelny Island, the largest of the New Siberian Islands.
Ecology
The Kolyma Lowland, the area where the Bolshaya Chukochya flows, has many lakes and marshes. A great variety of birds, like Siberian cranes, waders and sandpipers, make their habitat in this riverine area.[4]
Fossil insects, early Pleistocene equids and mammoths have been found in the basin of the Bolshaya Chukochya.[5]
