Uel Tympychan

The Uel-Tympychan rises on the Lena plateau in the south-eastern part of the Central Siberian uplands. It joins the Kurung-Tympychan to form the Tympychan, a tributary of the Nyuya and ultimately the Lena. The streams run through the forested interior of the plateau, where long winters freeze the ground and waterways. Their waters eventually reach the Lena, which carries them north to the Arctic Ocean.
