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 3/4 mile deep and 2.5 miles wide
4. Great Blue Hole, Belize
Situated 60 miles off the mainland of
Belize is this incredible. Geographical phenomenon known as a blue hole. There are numerous blue
holes around the world but none as stunning as this one.
At surface level the near perfectly circular hole is 1/4 mile wide, the depth in the middle
reaching 145 meters. Obviously the hole is a huge hit with divers. Read more here.
5. Mirny Diamond Mine, Serbia
I’m pretty sure most people have seen
this one. It an absolute beast and holds the title of largest open diamond mine 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 being sucked in.
The red arrow in the photo above is pointing to a huge truck.
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 even has its own airport with a runway
large enough to accommodate a Boeing 737. It also looks equally as cool when the surrounding
water is frozen.
7. Sinkhole, 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.
These photos are of a sinkhole which occurred early this year in Guatemala. The hole
swallowed a dozen homes and killed at least 3 people.
Officials blamed the monster of a hole on a ruptured
sewage pipe.
