This is the moment more than 3,000 reindeer block a snow-covered road as they are herded through the freezing Siberian landscape.
The footage, which appears to have been taken on a mobile phone, shows a river of the festive animals walking past the stationary car and on both sides of the road.
It was taken by a Russian journalist on the 223-mile highway that links the isolated towns of Salekhard and Nadym, about 2,000 miles north-east of Moscow.
The reporter said it took 15 minutes for the animals to pass.
The clip, filmed out of a stationary car on a snow-covered road, shows the reindeer passing in a line that stretches as far as the eye can see.
Panning the camera behind, the line appears to be just as long in the other direction.
At one point a large group of reindeer's approach, the males with their antlers held high, that block the road entirely.
One car was shown that had been stopped on the road by the animal traffic
Reports said there were around 3,000 reindeer in total that were being herded by indigenous Nenets people.
Reindeer herding is a traditional occupation in several northern Russian regions including Yamalo-Nenets Autonomous Okrug, where the footage was shot.
It is a nomadic profession as the animals need to regularly migrate to new grazing areas.
According to local media, there are around 2.5 million domesticated and semi-domesticated reindeer that support the livelihood of around 100,000 herders around the world.
Yamalo-Nenets Autonomous Okrug is said to be home to around 760,000 reindeer.
