1.The Door to Hell, Derweze, Turkmenistan
It’s only 98 feet deep, but it’s always on fire. It does seem to be some sort of gateway to hell, which means it may be safer to visit it with a pastor or someone from the destroyer.
2.Chand Baori, Indian State of Rajasthan
This stunning 100-foot-deep stairwell seems to be a terrible downstairs. It is also one of the man-made holes on this list. Ok, at least I assume it is because I suspect that water can erode the perfect staircase – not to mention a thousand times.
3.The Kola Superdeep Borehole, Russia
Guys, this is very deep. It even says this in the name. This hole is about 22,000 feet deep and there is no other reason than scientific research to dig what happens if a hole that is 22,000 feet deep is drilled.
4.Berkeley Pit, Butte, Montana
This pit used to be a copper mine and is now filled with strong acid water. This is how it gets that strange, dangerous color. It is about 1780 feet deep and is given or taken some.
5.Glory Hole, Monticello Dam, California
It is a deep hole called the Glory Cave, which absorbs 48,000 cubic feet of water per second. You know where I am going.
6.The Big Hole, Kimberley, South Africa
It is said to be 3,599 feet deep (say 3,600 feet, no one will know). This hole is actually a large mine, not dug by nature, but dug by us. We have done it all by ourselves. It also has a very inspirational name, which is too bad.
7.Great Blue Hole, Belize
This hole is 407 feet deep and it may be the most inspirational name in the world. It became famous after being named one of the best dive sites in the world, and it is currently used to study marine life.
