Siberia is a huge area of land in northern Asia. It has two great rivers; the Yenisei and the Lena, which flow across the entire territory of Siberia. The world's deepest lake, Lake Baikal, is also located in Siberia. Siberia also boasts the largest lowland area, the West-Siberian Plane, which covers 2.7 million kilometers of Siberia's territory. Much of Siberia is a tundra, running through various forests and swamps. Mountains border the area. Of course, Siberia has a cold climate.
            Many indigineous tribes lived in Siberia, and even earlier, it was a part of the early humans and the Ice Age. Such animals like the Woolly Rhino, Cave Bear, and the Mammoth once roamed the expansive tundra.
