Amazing holes - cool pictures

Amazing Holes
Looking at photos like these fascinates me.
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 ton's 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
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 belonging to Monticello dam in California
and it's the largest in the world. 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 slightly dead body would shoot out near the bottom of the dam. (below)
 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 3/4 mile deep and 2.5 miles wide.
 4. Great Blue Hole , Belize
 Situated 60 miles off the mainland of Belize this is an 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.
5. Mirny Diamond Mine , Serbia
 I'm pretty sure 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.
 The red arrow in the photo above is pointing to a 50 ton truck.
 6. Diavik Mine , Canada
 This incredible mine can be found 300km northeast of
Yellowknife in Canada .
(It's amazing that it doesn't fill up with water, being surrounded by it.)
 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, or when drout causes the water table to drop, leaving large sub surface voids that can 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 23 people.

Officials blamed the monster of a hole on a ruptured sewage pipe but geologists know that such a hole can open up under anyone's home.  Hector Andreas had just gotten out of bed when the floor went out from under his home, leaving him stranded along the
existing wall with just enough floor to escape certain death. 
8.  Bowling Green, KY
Two classic Corvettes emerged from a giant sinkhole that gobbled up those and six other prized vehicles that remain trapped beneath the National Corvette Museum in Kentucky. Here is one:
