Course The Siligir is formed in the Central Siberian Plateau at the confluence of the long Orto-Siligir (Орто-Силигир) and the long Usuk-Siligir (Усук-Силигир). The river flows initially northwards, bending to the NNE after a stretch, and then to the northeast. Finally it bends again to the north and meets the right bank of the Olenyok from its mouth. The confluence is downstream of Olenyok village, one of the few inhabited localities of the area. The river is frozen between early October and the second half of May.nature.ykt.ru (Силигир)
