Tumul
Tumul lies by the Betyuke channel of the Aldan in eastern Yakutia. The Aldan, one of the great tributaries of the Lena, gathers rivers from a broad mountainous basin before continuing northward. Channels and islands divide its waters in the lowlands, while forests extend across the surrounding country. The river forms a natural connection between the interior and the Lena, whose waters reach the Arctic Ocean.
