13 totally bizarre holes in the earth

We're not talking about the normal holes it is something bizarre. These holes are naturally occurring that formed naturally and named as black hole or sinkhole depending on the place where it formed. Out of all, let me show you the most amazing, earth opening, frightening and earth-shaking sinkholes, and black holes.

1. The Darvaze Gas Crater

In Turkmenistan is the burning, stinking, sulfurous crater known as the Gate to Hell.  In 1971 Soviet engineers were drilling the area known to hold one of the largest deposits of natural gas.

2. The Well Of Chand Baori

Legend has it that this 13 story water well was carved out of the rock by spirits in a single night, and dedicated to the Hindu goddess of happiness.  There are 3500 perfectly symmetrical steps leading to the bottom, which is about 10 degrees cooler than at the surface.

3. The KTB Superdeep Borehole

Starting in 1982, the German Ministry of Research began a scientific exploration drilling program, deep into the earth's crust, that would last more than 12 years and cost more than a third of a billion dollars, their most expensive geo-science project ever.

4. The Guatemala City Sinkhole

In 2010, a massive hole suddenly opened up in the middle of the city and swallowed a three-story factory house, along with fifteen people inside. The cause was attributed to Tropical Storm Agatha, which impacted Guatemala just three days after the eruption of Volcano Pacaya.

5. Siberian Craters

It's located on a peninsula and was allegedly noted by locals on September 2013.Yet another new geological phenomenon was discovered in 2014 when a reindeer herder discovered a two hundred foot crater in a remote area known as The End Of The World.  Recently, three holes have been found in Siberia. Out of the three holes, the third one is a nearly perfect cone-shaped hole which is about 4 meters (13 ft) wide and 60–100 meters (195-330 ft) deep. The other two holes (1st holes) measure 50–100 meters (165–330 ft) and the second hole measure 15 meters (50 ft) wide. These holes were formed by a force that came from inside the Earth.

6.  Indiana Dunes National Park

An amazing new geological phenomenon was only discovered in the last few years when shifting sands have suddenly opened up massive sinkholes beneath travelers' feet. In 2013, a six-year-old boy exploring the sand dunes of Mount Baldy in Indiana Dunes National Park was swallowed by a sinkhole that suddenly appeared beneath him. The boy recovered after a three-hour ordeal in which he was buried under a little more than 3 meters (11 ft) of sand, and other sinkholes have been randomly appearing ever since. In 2013, a six-year-old child searching for sand dunes of Mount Bally in Indiana Tibba National Park was swallowed by a sinkhole who suddenly appeared under it. The boy was recovered after three hours of examination, in which he was buried under 3 meters (11 feet) of sand, and other sinkholes were randomly visible.

7. The Kola Superdeep Borehole

All the holes in the Earth's crust are not made naturally or have emerged mysteriously. From 1970-1994, geologists dug up the largest hole in the earth in Russia, which nobody had ever seen in the name of science. The result was the Kola Superdeep Borehole, and it finally reached a depth of 12 kilometers (7.5 miles).

9. Dead Sea Sinkholes

It's still a mystery that how many sinkholes have appeared around the Dead Sea. However, it's estimated that 2,500 have been formed since 1970, 1,000 in the last 15 years. Just like holes seen in Siberia, they're the indications of environmental change. The Jordan River falls into the Dead Sea. The draining of the lake is resulting in the sinkholes, along with the failure of the resorts and hotels that were once located alongside the lake, but now find their location miles away from the shore. At one time, the sea was a popular destination for visitors making religious pilgrims or those who hope to be healed by its magical water. Now, there are more frequent-looking warning signs that alert the display of automatically visible sinkholes.

10. Dean’s Blue Hole

11. The Devil’s Sinkhole

In Edwards County, Texas, there's a massive underground chamber called, Devil’s Sinkhole; about 15 meters (50 ft) wide, leading to a cavern 106 meters (350 ft) deep that now is home to one of the largest known colonies of Mexican free-tailed bats. In the summer months, visitors can see more than three million bats from the entrance to the sinkhole as they are not actually allowed into the cavern.

12. The Sawmill Sink

Another blue hole in the Bahamas, known as the Sawmill Sink. It has more scientific significance than only attracting extreme sports athletes. The sinkhole was the site of an archaeological dig that has changed the perspective of scientists thinking that landscape was like 1,000 years ago. This blue hole holds the debris of one of the earliest known residents of the Bahamas, approximated about 1,050 years old.

13. The Black Hole Of Andros

The Black Hole of Andros, located on the South Andros Island in the Bahamas, does not share clear, dark blue color similar to other holes in the region. It is not very black, but a very dark purple, and that is because it has a hole below 18 meters (60 feet), the thick, toxic layer of bacteria floating between a heavily aerate upper level and the oxygen-free lower level. The island is unfriendly, inhospitable, and unfavorable. It features more than mud and it's nearly impossible to reach the Black Hole without specific equipment like helicopters. The layers of water here contains high levels of harmful hydrogen sulphide. They also have bacteria that has not only developed between the water levels but also resulted in the water conservation conditions that have remained unchanged for the last 3.5 billion years.
