Frozen Air Bubbles II Baikal Lake - Russia It's the oldest and deepest freshwater lake in the world, reaching depths of more than 5,000 feet, stretching for nearly 400 miles across Siberia, and with water so clear you can see 130ft beneath the surface. Come winter, it becomes encased with a five to six foot-deep layer of ice, trapping air bubbles which look like intricate glass beads rising up from the deep.
