A Moscow-based photographer has captured the otherworldly beauty of one of the world’s deepest and oldest lakes, Lake Baikal in southern Siberian, in a photo series. /Кристина Макеева

In winter, the lake can be so transparent that its entire contents all the way down to its bottom can be seen: fish, green stones, plants and bluish gulf. /Кристина Макеева

As the biggest reservoir of fresh water on Earth, Lake Baikal is about 600 km long and 1,642 meters deep. /Кристина Макеева

There are only two other lakes deeper than 1,000 meters: Africa’s Lake Tanganyika (1,470 m) and the Caspian Sea (1,025 m) between Europe and Asia. /Кристина Макеева
