The Deepest Holes on Earth

Holes: The Wonders of the Earth

What is the deepest hole on Earth? The Kola Superdeep Borehole, which was drilled by a Soviet Union drilling rig in what is now Russia, has been measured to be 12.262 kilometers deep and ranks as the deepest man-made hole ever dug.

The Mariana Trench, located in the western Pacific Ocean near Guam, measures 10.911 kilometers deep and is considered to be one of the most remote places we know about on Earth; it took scientists two years just to explore this area because they had to travel for days before arriving here! It also contains Mount Everest’s worth of water weight.


One of the other deepest holes on Earth is the Puerto Rico Trench, which measures 18.980 kilometers deep and contains more than three times as much water as all of the Great Lakes combined!

The deepest holes on Earth are difficult to measure because there’s no such thing as being “at” 0 feet depth when you’re in space; however, our human surface is about 12 kilometers deep if you add up everything below us (oceans, sediment layers).

Meteors can also leave a hole when they hit Earth, and these can be up to 100 kilometers deep.

The deepest lake on Earth is Baikal, which is 1637 meters deep.

Deep holes can also appear when the ground moves during an earthquake or volcanic eruption.

The deepest hole on Earth is the Mponeng gold mine in South Africa, which is an amazing 12 kilometers deep and was one of the first to be built with a bucket-wheel excavator instead of clunky old shovels!

It has over 800 meters (half a mile) of rock that we call “overburden” or material covering it – this means workers had to dig through two miles worth of earth just to reach its precious gold deposits.

Some people suppose these giant holes were formed when asteroids from outer space hit our planet billions of years ago.

In case that you need to dig holes on your property, not as big as those mentioned here though, then Dobson Excavations are a company for you!
