Les Diamants du Pôle
Opis filmu
Opis oryginalny: francuski
Extracting diamonds is no easy feat. By 50 degrees below 0 and polar winds, thousands of men work in giant open-air mines of 1,5 km diameter. These holes the size of lunar craters are excavated by huge bulldozers that dig sometimes 300 meters deep into the permafrost and then into black lava rock of over 53 million years old.
