Marxa
The Markha flows across the Lena Plateau before joining the Lena from the left. At its mouth the river meets one of Siberia's great waterways, which continues northeast through central Yakutia. The Markha runs for hundreds of kilometres through wooded plateau country, distinct from the larger river of the same name in the Vilyuy basin. Its valley and the Lena together connect the surrounding forest lands with the wider river system.
