ProgressionAnabar→Laptev Sea

The river flows north of the Arctic Circle, in the northern limits of the Central Siberian Plateau and the North Siberian Lowland. The area is very cold and desolate, devoid of settlements.[2]

The Kuonamka Formation is a Cambrian large igneous province in the northeastern Siberian platform.[3]

Course

The Malaya Kuonamka "Little Kuonamka" is the second largest tributary of the Anabar. The river has its source in an elevated swamp at an altitude of 375 m (1,230 ft) in the eastern side of the Anabar Plateau. Together with the 559 km (347 mi) long Bolshaya Kuonamka "Big Kuonamka" to the west, it is one of the two rivers that form the Anabar at their confluence. In their last stretch both rivers flow roughly northwards. Finally they meet where the Anabar river proper begins, 380 km (240 mi) from its mouth in the Laptev Sea.[4][5][2]

The river is fed by rain and snow. It is frozen between late September and late May. The longest tributaries are the 223 kilometres (139 mi) long Usumuun (Усумуун), the 217 kilometres (135 mi) long Delinde (Дьэлиндэ), as well as the 198 kilometres (123 mi) long Maspaaki (Маспаакы) from the right.[1]
