Image taken 7/27/2000: The Lena River, some 2,800 miles (4,400 km) long, is one of the largest rivers in the world. The Lena Delta Reserve is the most extensive protected wilderness area in Russia. It is an important refuge and breeding grounds for many species of Siberian wildlife. The Lena Delta can be found on Landsat 7 WRS Path 131 Row 8/9, center: 72.21, 126.15.

These views of the Russian Arctic were acquired by NASA Terra spacecraft on July 11, 2004, when the brief arctic summer had transformed the frozen tundra and the thousands of lakes, channels, and rivers of the Lena Delta into a fertile wetland.
