Siberian

Siberia is a vast Russian province encompassing most of Northern Asia, with terrain spanning tundra, coniferous forest and mountain ranges including the Ural, Altai and Verkhoyansk. Lake Baikal, in its south, is the world’s deepest lake, circled by a network of hiking paths called the Great Baikal Trail. The Trans-Siberian Railway passes Baikal on its route between Moscow and the Sea of Japan. ― Google
