Crossing a frozen lake, Baikal, from Russia to Magnolia.

Lake Baikal, the world's oldest and deepest freshwater lake, curves for nearly 400 miles through south-eastern Siberia, north of the Mongolian border. At its deepest point, it is over 5,000 feet (1,637 meters) deep. It is the world's largest freshwater lake in terms of volume. #lake Baikal Russia #lake Baikal facts #lake Baikal seals #lake Baikal frozen #lake Baikal winter
