Taymyr – the northernmost Asian Peninsula located between Yenisei Bay of the Kara Sea and Khatanga Bay of the Laptev Sea in Taymyr (Dolgano-Nenets) Autonomous Area, Russia. The northernmost point of T. is Cape Chelyuskin. The length is around 1,000 km, and the width is over 500 km. The area is approximately 400,000 km2. The coastline is rugged. By surface pattern T. is divided into three parts: (1) the North Siberian Lowland having gently rolling and ridgy topography, with Lake Byrranga in the northern part; (2) Byrranga Mountains up to 1,146 m high from the Pyasina River to the Laptev Sea coast with contemporary glaciers in the eastern part (area 30.3 km2); and (3) coastal plain along the Kara Sea coast. The topography is a hilly lowland. The large rivers are the Pyasina, the Upper and the Lower Taymyra, and the Khatanga. Permafrost is widespread. The flora is represented by tundra, with light forest in the south. The first reports on Taymyr go back to the beginning of the seventeenth century, when first Russian manufacturers appeared there and Russians started exploration of northern and eastern regions of Taymyr. The coasts of the peninsula were partly described and approximately mapped for the first time in 1735–1742 by participants of the Great Northern Expedition (1733–1743), by lieutenants V.V. Pronchishchev and Kh.P. Laptev, and navigators F.A. Minin, D.V. Sterlegov, and S.I. Chelyuskin. Basically, the result of this expedition was discovery of a new peninsula. Russian maps of the seventeenth to the beginning of the eighteenth century show this coast almost flat. The peninsula was called after the river Taymyr.
