Taymyr, also spelled Taimyr, lies on the hilly Taymyr Peninsula, the most northerly part of the Eurasian continent, and extends south to the northern edge of the Central Siberian Plateau. The Taymyr Peninsula lies between the Yenisei Gulf of the Kara Sea and the Khatanga Gulf of the Laptev Sea. It’s the most northern peninsula in Asia. The length of the peninsula is about 1000 kilometers. Its width is about 500 kilometers. The total area of the peninsula is about 400.000 square kilometers. It is located beyond the Polar Circle in the permafrost zone.
The Taimyr Peninsula is located in the arctic and subarctic zones. That’s why the climate here is exceptionally severe, with prolonged, bitter winters. The coasts of the Taimyr Peninsula are frozen most of the year between September and June on average. Almost everywhere is tundra of mosses, lichens, and bog. The average winter temperature can be -45’- 60’C. Winters are harsh with frequent blizzards and extremely low temperatures. The summer is usually short and cool.
Taimyr is one of the richest regions in Russia. It is rich in gas, oil, precious metals, hydroelectric energy and much more.
The surface of the peninsula is divided into three main parts: the North Siberian Lowland, the Byrranga Mountains and the coastal plain along the Kara Sea shore.
The Byrranga Mountains are located within the vast Taymyr Peninsula. The Byrranga Mountains are a mountain range in the middle of the Taymyr Peninsula, Siberia, located north and west of the Taymyr Lake. They run for about 1,100 km, forming a looping curve that runs roughly in a southwest to northeast direction. The Byrranga range has deep canyons and ravines, as well as a few small glaciers in its eastern zones. These mountains are not very high, being on average about 500 m. The highest peak is 1,146 m.
The Cape Chelyuskin, the northernmost point of the Eurasian continent, is located at the northern end of the Taymyr Peninsula. The area includes the Severnaya Zemlya archipelago in the high Arctic. Its total area is 37,000-square-kilometres. Severnaya Zemlya (Northern land) was first noted in 1913 and first charted in 1930-32, making it the last sizeable archipelago on Earth to be explored. The main urban settlements of the Taimyr Peninsula are:
- Dudinka, the capital of the former district;
- Dikson, a small port at the mouth of the Gulf of Yenisei;
- Khatanga;
- Snezhnogorsk;
- Norilsk with its satellites Talnakh, Kayerkan, Oganer;
There are three main reserves on the Taimyr Peninsula. They are the Putorana State Nature Reserve, the State Taimyr Biosphere Reserve and the Great Arctic State Nature Reserve.
