The Lena River Delta, Russia – June 30th, 200973.0N 127.0E
The Lena River runs horizontally across the left side of this image, forming an immense delta by its mouth in Sakha Republic, in the far north of eastern Siberia, Russia. The Lena empties into the Laptev Sea, which is mostly covered in ice, here.
Much of the delta is protected as the Lena Delta Wildlife Reserve, a scientific nature reserve with a total land area of 61,000 square kilometres (23,552 sq mi), making it the largest protected area in Russia.
The delta itself has a size of about 30,000 square kilometres (11,583 sq mi), making it one of the largest of the world. It protects large concentrations of birds, including swans, geese and ducks, loons, shorebirds, raptors and gulls. It is also an important fish spawning site.
