The Lena is a river in the Russian Far East and is the easternmost river of the three great rivers of Siberia which flow into the Arctic Ocean, the others being Ob and Yenisey.[note 1] The Lena river is 4,294 km (2,668 mi) long and has a capacious drainage basin of 2,490,000 km2 (960,000 sq mi); thus the Lena is the eleventh-longest river in the world and the longest river entirely within Russia.[6] Geographically, permafrost underlies all the Lena River's catchment and it is continuous in over 75 percent of the basin.[7]
