The Baky is a left tributary of the Yana. It has its sources in the northwestern slopes of the Khayrdakh Ridge (Ã¥ðùÃÂÃÂôðàÃÂúøù úÃÂÃÂö), part of the Kular Range of the Verkhoyansk system. The river flows first northeastwards, skirting the mountain area. It meanders within a wide valley heading in an eastern direction in its lower course. Osokhtokh village is located by the banks of the Baky in its last stretch, where the river meanders very strongly. Near the left bank of the Yana the Baky divides into three branches, joining the river from its mouth.
