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 killing at least 3 people.
Officials blamed the monster of a hole on a ruptured sewage pipe.
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 looks equally as cool when the surrounding water is frozen.
This is when the ice-road truckers bring supplies.

Mirny Diamond Mine , Serbia
Most people have seen this one. It's 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.

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.

Hoover Dam
Hoover Dam, also known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado river, on the border between the U.S.states of Arizona and Nevada. When completed in 1935, it was both the world's largest electric power producing facility and the world's largest concrete structure. It was surpassed in both respects by the Grand Coule Dam in 1945. It is currently the world's 34th largest hydroelectric generating station

Kimberley’s Big Hole – South Africa
Apparently the largest ever hand-dug excavation in the world, this 1,097 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.
