8 Amazing Holes!

These holes are not only amazing, but some of them

are really terrifying - especially #8! The sheer scale

of these holes reminds you of just how tiny you are.

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.

The hole can be seen at the top left of the photo above.

If you were to jump in for some reason, your body would

shoot out near the bottom of the dam (below). There is

one person known to have had this experience. She did

not live to tell of it.

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.
