Amazing Holes
The Mirny Diamond Mine, Serbia. Holds the title of largest open diamond mines in the world. At 525 metres deep, with a top diameter of 1200 metres, there's even a no-fly zone above the hole due to a few helicopters having been sucked in. Awesome!
The Diavik Mine, Canada. This mine is so huge and the area so remote that it has its own airport with a runway large enough to accommodate a Boeing 737. Incredible!
St. James's Park, Newcastle. This hole reputedly contains the most fertile soil on the planet. Liberally splattered with the most expensive shit in the world once a fortnight. Unbelievable!
