Lena River

The Lena River is one of the longest rivers in the world, flowing approximately 4,400 miles across Siberia in Russia. It begins in the Baikal Mountains and drains into the Arctic Ocean. The river's vast basin supports diverse ecosystems and is vital for transportation, fishing, and local communities. Its flow varies seasonally, with significant ice cover in winter. The Lena plays a key role in the region's climate and environmental processes, serving as a crucial waterway in one of the world's most remote and least inhabited areas.
