Amazing China EP17: 

The Unfrozen River

In winter, Arxan, a city in northern China becomes a world of ice. Its rivers become frozen. All except one.

Upstream of the Khalkhyn Gol River, there is a stretch around 20 kilometers long. Even in winter, when the air temperature typically drops to minus 40 to 30 degrees Celsius, this section remains ice free. People call it The Unfrozen River.

Its secret lies deep beneath the river bed, where the river passes over an area of geothermal activity near Arxan. The heat from below, raises the temperature allowing the river water to stay above freezing point. And so it remains ice free.

During the harsh winter, it even becomes a spa for animals. A group of cattle are strolling along the river bank. They can't wait to wade through the water.

Look closely and you'll see steam rising from the surface of the river.

Such a nice warm bath! Let's leave the cattle to enjoy it!
