Yerkyutey
The Yerkyutey joins the Ygyatta in the forest country of western Yakutia. The Ygyatta rises on the Vilyuy Plateau and flows south to join the Vilyuy, a great tributary of the Lena. Its lower course winds through broad loops and a wide floodplain. Forest, streams and lakes cover the inland plateau, where winter ice lasts for months and the summer season is short.
