Siberia's Lena Delta

April 20, 2011
The Lena River, some 2,800 miles long, is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean and is one of the largest rivers in the world. The Lena Delta Wildlife Reserve, a protected wilderness area, provides an important refuge and breeding ground for many species of Siberian wildlife, and is also an important fish spawning site.
