Nenets herders move seasonally with their reindeer, traveling along ancient migration routes. During the winter, when temperatures can plummet to -50C, most Nenets graze their reindeer on moss and lichen pastures in the southern forests, or taiga. In the summer months, when the midnight sun turns night into day, they leave the larch and willow trees behind to migrate north. By the time they have crossed the frozen waters of the Ob River and reached the treeless tundra on the shores of the Kara Sea, they might have traveled up to 1,000 km. #
