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.

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.
5.
Mirny Diamond
Mine
,
Serbia

This one is
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 having been
sucked in.

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.
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
And
the most terrifying one of all?
This
is the famous ’Rat Hole’ that you have
heard about.
It
is capable of swallowing trillions and trillions of
U.S.
Dollars...
Annually! Never to be heard from again.
Rest in Peace
