Life Of Siberian Reindeer Herders, Yamal, Russia.

Caribou have been a major source of subsistence for Canadian Inuit.
In history
Both Aristotle and Theophrastus have short accounts - probably based on the same source - of an ox-sized deer species, named tarandos, living in the land of the Bodines in Scythia, which was able to change the colour of its fur to obtain camouflage. The latter is probably a misunderstanding of the seasonal change in reindeer fur colour. The descriptions have been interpreted as being of reindeer living in the southern Ural Mountains at c. 350 BC
