The Earth features a range of man-made and natural holes, some of which will leave you in complete awe. Today, we’re going to take a look at 6 of the most incredible holes found on Earth:
Y-40 Deep Joy
You will have to take a very deep breath if you want to reach the bottom of the world’s deepest swimming pool,the Y-40 Deep Joy, as at its deepest point it is the same as 9 double decker buses placed on top of one another. As you might have guessed from its name, the pool is 40 meters deep and it’s located in Italy at the Hotel Terme Millepini.
Eiksund Tunnel
Opened in 2008 as part of the Eiksundsambandet Project, the Eiksund Tunnel in Norway, along with other tunnels and bridges, were built to provide a permanent route between Hareidlandet and the rest of the country. It travels deeper underwater than any other transportation tunnel, reaching 287 meters below the surface at its deepest point. The tunnel runs 7.8 kilometers and enough rock was excavated to fill football field 175 meters high.
The Krubera cave
The Krubera cave (also known as the Voronya cave) is the world’s deepest cave with an altitude separation between entrance and deepest known point of 2.2 km.Located in the Arabika Massif on the edge of the Black Sea, it extends a total of 13.4 km – as far as we know. The cave was discovered by French explorers in 1956 as they first plummeted 1 km deep into the hole.
Superconducting Super Collider (SSC)
The Superconducting Super Collider (SSC) was set to be a gigantic particle accelerator underneath the ground encircling the town of Waxahachie, Texas. The project was approved in 1987 and the initial estimated cost was $4.4 billion. By 1993, the estimated total cost for the SSC’s construction had risen to $11 billion, at which point the US Congress officially ended the project. 24 kilometers of tunnel was dug at a cost of $2 billion and they are now left to just collect rainwater.
Woodingdean Well
In 1858, in the town of Woodingdean, England, plans were set to dig a 122 meter deep brick-lined well. After two years of purely human powered digging, they had reached 134 meters deep, however, no water had yet been found. They tried digging 4 horizontal tunnels still to no prevail so they decided to dig down again from the end of one of the horizontal tunnels. Finally, on March 16, 1862, they had reached 392 meters and the bottom of the well began to rise up. After a 45 minute climb back up, the diggers watched as the well filled with water.
TauTona Mine
TauTona (meaning “great lion” in Setswana) is a South African gold mine that is 3.9 kilometers deep at its lowest point, making it the world’s deepest mine. It has been in operation since 1962 and 5,600 miners can be found working along the 800 kilometers of tunnels. An elevator ride from top to bottom can take around an hour and temperatures in the mine can reach as high as 55 degrees Celsius.
Dean’s Blue Hole
The deepest blue hole (which are holes located underwater) that’s been discovered so far is Dean’s Blue Hole in the Bahamas. Reaching a staggering depth of 202 meters, Dean’s Blue Hole is more than twice as deep as most other blue holes, making it a favourite of professional deep-sea divers.
