Course
The Kotuykan has its source in the highest part of the Anabar Plateau. It is a fast-flowing river that flows westwards in a deep valley, often surrounded by picturesque cliffs of marine sediments exposed by erosion that are 1.5 billion years old.[2]
The Kotuykan joins the right bank of the Kotuy as the latter flows from the south across the western side of the Anabar Plateau, 234 kilometres (145 mi) from its mouth and 461 kilometres (286 mi) from the mouth of the Khatanga in the Laptev Sea.[3]
Its main tributaries are the 102 kilometres (63 mi) long Ilya (Илья) and the 54 kilometres (34 mi) long Dyogdyo (Дёгдё).
