12 real-life holes on earth that look like fantastic gates to other worlds (19 photos)
If you want to tickle your nerves a little, then be sure to watch this post to the end. When will you have another chance to look the abyss straight in the eye? 
Our planet is full of various surprises. One of them is geological formations (in other words, holes) that appeared due to natural processes or human actions. They can be found on the ground, underwater and even in caves. Some of them are of such an amazing scale that looking at them, you feel a little uneasy, because they are incredibly similar to mysterious doors leading to other worlds. Who could live at the bottom of these amazing abysses - a fire-breathing dragon, a kraken, or something worse? The answer to this question will depend on your imagination.

Berkeley Pit, Montana, USA 
In front of you is an old copper mine with a diameter of 2.7 kilometers and a depth of more than 500 meters. When it closed, the pumps that drew water were stopped. As a result, a lake formed in place of the pit.
