From Sinkholes to Mines to Stepwells - 10 Amazing Holes In The Earth
Mankind is willing to go to great lengths to obtain the minerals buried deep in the Earth's crust. To fully appreciate just how much effort we've put in, you only need look at some of the immense mines we've dug up.
While not all of the holes in today's top 10 are man-made, most of them are the result of mining. There are also a number of natural holes that are, quite honestly, scary and awe-inspiring to behold. Today we'll present you with the 10 most amazing holes, both natural and man-made.
Bingham Canyon Mine, Utah
The Super Pit may be big, but Bingham Canyon is the deepest, and shows no sign of slowing. In operation since 1906, Bingham Canyon has been one of the most productive mines in the history of the world, turning out copper, silver, gold, and molybdenum in mass quantities, to the tune of nearly $2 billion worth of minerals yearly. With plans to continue operations through 2030, the deepest open pit mine in the world will likely keep growing.
Great Blue Hole, Belize
An underwater sinkhole, with amazingly blue waters in and around it, the Great Blue Hole is a diving mecca, having attracted some of the most famous undersea explorers in the world. 300 meters wide and 124 meters deep, it is an ancient hole, and the only one on this list not caused in some way by man – stalactites in the hole show that the cave was formed over a period of 140,000 years, with the most recent formation 15,000 years ago. The hole is quite a ways off of the coast of Belize – 70 kilometers, to be exact - so if you want to check it out, you'll need an entire day.
