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.
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.
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.
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.
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.
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
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.
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.
