Anyone like big holes?...

I was searching for something engineering related online and randomly stumbled across this bad boy 
...
So did a bit more searching and found these on various other sites....
Glory Hole - Monticello Dam, California. 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.
A glory hole is used when a dam is at full capacity and water needs to be drained from the reservoir.
KimberleyBig 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.
BinghamCanyon 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 � miles deep and 2.5 miles wide.
In February of 2007, a sinkhole in Guatamela collapsed, killing two children as their home, and dozens of others, were swallowed into the pit. The blame for this astoundingly large hole was placed on a ruptured sewer pipe.
Diavik Mine, Canada
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.
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 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 Great Blue Hole — the world’s largest blue hole — is a massive underwater sinkhole off of the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 60 miles (96 kilometers) east of the Belize mainland. The hole is near perfectly circular in shape, more than 1,000 feet (305 meters) across and 480 feet (146 meters) deep.
