Amazing Circular Art by Nature & Man around the world

circular_holes

Most spectacular natural and manmade holes in the face of the earth. Some of these are the result of man’s search for mineral wealth, while some are nature’s work creating some astounding holes.

Darvaza – The Burning Gates

Darvaza - The Burning Gates

In 1971, geologists discovered a huge underground deposit of natural gas on this site. And while excavating, a whole drilling rig fell into an underground cavern. Natural gas started coming up from the hole. To prevent gasses from escaping, it was set alight and it continues to burn even today. The crater measures roughly 60 meters in diameter and 20 meters deep and is located in Turkmenistan.

These  photos are of a sinkhole that occurred early  this year in Guatemala . The hole swallowed a dozen homes and killed at least 3 people.

Diavik  Mine, Canada

The 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. It looks equally cool when the  surrounding water is frozen.

Mirny  Diamond Mine , Serbia

I’m  pretty sure most people have seen this one. It’s an absolute  beast and holds the title of largest open diamond mines in the  world. At 525 meters deep, with a top diameter of 1200 meters,  there’s even a no-fly zone above the hole due to a  few helicopters having been sucked in.

Great  Blue Hole , Belize

This  incredible geographical phenomenon known as a blue hole is  situated 60 miles off the mainland of Belize. There are  numerous blue holes around the world, but none as stunning as  this one.

Bingham  Canyon  Mine, Utah

Bingham Canyon Mine, Utah

This is  supposedly the largest man-made excavation on earth. Extraction  began in 1863 and still continues today, the pit increasing in size  constantly. In its current state the hole is ? miles deep and 2.5  miles wide.

Glory  Hole – Monticello Dam, California

Glory Hole - Monticello Dam, California

This is  the ‘Glory Hole’ at Monticello dam, and it’s the largest in the  world of this type of spillway, its size enabling it to consume  14,400 cubic feet of water every second.

Kimberley  Big  Hole – South Africa

Apparently the largest ever  hand-dug excavation in the world, this 1097  meter deep mine yielded over 3 tons of diamonds before being closed in  1914.
