Nalyachchyya
The Nalyachchyya joins the Nelgese in northeastern Yakutia, among the ridges and valleys of the Yana basin. The Nelgese flows through mountain terrain to join the Adycha, which in turn reaches the Yana. Forested slopes and cold streams break up the highland landscape. The great river system carries water northward toward the Laptev Sea, far beyond these inland valleys.
