Ölöön

The Olenyok flows across northern Siberia to the Laptev Sea, where its lower course opens into a delta of channels and islands. The Bur, Khorbusuonka and Kelimyar are among the rivers that join it before it reaches the coast. Far beyond the Arctic Circle, the river passes through a landscape of tundra, wetlands and low hills, frozen for much of the year and briefly transformed by summer melt.
