Okay, since Njaco has graciously allowed me to post on his thread, I bring you...
HOLES
First up 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

Glory Hole - Monticello Dam, California
Lucky13 knows what a glory hole is but for the rest of us laymen, 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.

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 miles deep and 2.5 miles wide.

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.

I'm pretty sure most people have seen this one. It's an absolute beast and holds the title of largest open diamond mines 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.

I saw that too. Couldn't tell if it was a sun glare on the camera or the twister that "sucks helicopter to the bottom".
