What is "big hole"

The Big Hole, Open Mine, Kimberley Mine or Tim Kuilmine is an open-pit and underground mine in Kimberley, South Africa, and claimed to be the largest hole excavated by hand, although this claim is disputed.

Big Hole is a large maar (explosion crater) in the Fort Rock Basin of Lake County, central Oregon, northeast of Crater Lake, near Oregon Route 31. It is approximately 6000 ft (1820 m) across and deep.

It is close to another smaller, but less-eroded maar crater, Hole-in-the-Ground.
