Tupik
Tupik lies at the meeting of the Bugarikta and the Tungir, in the forested mountain country of the Olyokma basin. The Tungir flows north to join the Olyokma, a tributary of the Lena. Its valley forms part of a network of waterways crossing the northern reaches of Transbaikalia, where the long winters and rugged relief contrast with the brief season of open rivers.
