Lena and Vilyuy Rivers in Eastern Siberia, Russia60.3N 120.4E
The two white lines cutting across this winter image of Russian Siberia are the Lena River (below) and its left bank tributary, the Vilyuy River (above). Both appear white because their surfaces are frozen.
The Lena is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean and the 11th longest river in the world. The Vilyuy River is the longest tributary of the Lena in eastern Siberia.
