The taiga forests of Sibera stretch over a quarter of Russia's territory. These rarely explored woodlands are as dense as an Amazonian jungle with more than 62,000 sq miles completely uninhabited.
With endless miles of birch, pine and unpolluted waters, these forests are known today as Earth's last great wilderness.
Winters are long in the taiga, but due to its latitude, relatively mild compared to other parts of the country.
This forest is so remote that one family was entirely lost for decades until their chance discovery in 1978.
