1. 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.
The amount of earth removed by workers is estimated to total 22.5 million tons
2. Glory Hole - Monticello Dam, California
A glory hole is used when a dam is at full capacity and water needs to be drained from the reservoir.
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.
3. 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 ¾ miles deep and 2.5 miles wide.
4. 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
At surface level the near perfectly circular hole is ¼ mile wide, and the depth in the middle reaches 145 meters. Obviously the hole is a huge hit with divers
5. Mirny Diamond Mine , Serbia
6. Diavik Mine, Canada
This incredible mine can be found 300km northeast of Yellowknife in 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.
7. Sinkhole in Guatemala
A sinkhole is caused when water, usually rainwater or sewage, is soaked up by the earth on a large scale, resulting in the ground collapsing the surface
