HistoryEdit

In the summer of 1631, Russian pioneer Pyotr Beketov entered the Olyokma during his first voyage down the Lena and in 1636 he founded the present-day city of Olyokminsk near the mouth of the river on the left bank of Lena.[2]

Yerofey Khabarov used this river's route to travel from the Lena to the Amur during his mid-17th century expeditions.[1]

CourseEdit

The river is 1,436 kilometres (892 mi) long, and has a drainage basin of 210,000 square kilometres (81,000 sq mi).[3] The Olyokma rises in the Muroy Range, Olyokma-Stanovik Highlands (Олёкминский Становик), west of Mogocha. It flows north through remote terrain before joining the Lena near Olyokminsk.[4]

To the west is the Vitim, to the south the Shilka and Amur, and to the east the upper Aldan. Its right tributary, the Tungir [Wikidata], leads to a portage to the Shilka. Other tributaries are the Nyukzha [Wikidata] and the Chara.[2]
