It's an absolute beast and holds the title of largest open diamond mine in the world. The red arrow at the right is pointing to a 50 ton truck.
It is 525 metres 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.
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.
A sinkhole is caused when water (usually rainwater or sewage) is soaked up by the earth on a large scale, or when drought causes the water table to drop, leaving large sub surface voids that can result in the ground collapsing.
This is a sinkhole, which occurred early this year in Guatemala. The hole swallowed a dozen homes and killed at least 23 people.
Officials blamed this 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 got 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.
