On 6 June 1979, the world depth record held by the Bertha Rogers hole in Washita County, Oklahoma, United States, at 9,583 m (31,440 ft) was broken. In 1983, the drill passed 12,000 m (39,000 ft), and drilling was stopped for about a year for numerous scientific and celebratory visits to the site.
Where is the deepest hole in America?
The deepest hole within the U.S. is the Bertha Rogers gas well in Oklahoma at 32,000 feet (6 miles) deep.
Why did they stop digging the Kola Superdeep borehole?
Then it was the turn of the Kola Superdeep Borehole. Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible.
What was found in the Kola Superdeep borehole?
The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle. Among the more interesting discoveries: microscopic plankton fossils found at four miles down.
Who has dug the deepest hole on Earth?
America might have landed on the moon, but Russia drilled the deepest man-made hole on Earth. Since the early 1960s, scientists have attempted to drill down to the Earth’s mantle. It took 20 years, but Russia drilled down 40,230 feet into the earth, before heat forced work to stop.
Is there a bottomless pit in the world?
It’s true that there are plenty of deep holes that exist, but none are truly bottomless. In reality, even the deepest ones have never penetrated all the way down below the Earth’s crust. To get something deeper, we’ll have to use our imagination.
How deep can a sinkhole get?
What is a “sinkhole”? A sinkhole is an area of ground that has no natural external surface drainage–when it rains, the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep.
How deep can you dig into the earth?
Deepest drillings
The Kola Superdeep Borehole on the Kola peninsula of Russia reached 12,262 metres (40,230 ft) and is the deepest penetration of the Earth’s solid surface. The German Continental Deep Drilling Program at 9.1 kilometres (5.7 mi) has shown the earth crust to be mostly porous.
What was found in the deepest man made hole?
The 23 centimetres (9 in) diameter boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) in 1989, the deepest artificial point on Earth.

Where would you end up if you dug straight down?
If you’re a flat-Earther, you’ll eventually break through the bottom of the Earth and just fall straight down into eternal space because that’s how physics work. If you’re a hollow-Earther, you’ll eventually dig into a plesiosaurus nest and be eaten.
Has anyone ever dug into mantle?
Drilling To The Mantle Of The Earth : NPR. Drilling To The Mantle Of The Earth Fifty years ago, scientists attempted to drill deep through ocean crust to the Earth’s mantle, an endeavor called “Project Mohole.” That project failed, but scientists are sharpening their drill bits again.
Can you dig a hole to China?
Take a closer look at a globe: China is actually not antipodal to the United States. That would be impossible, since they’re both in the Northern Hemisphere. If you dug a hole from anywhere in the lower 48 states straight through the center of the Earth, you’d actually come out… in the middle of the Indian Ocean.
Why did Russia dig a hole?
Drilling the Kola Superdeep Borehole was, for the most part, purely science-driven. Soviet scientists wanted to learn more about our planet’s outermost layer, called the crust, to understand how that crust has formed and how it evolved.
How hot is it 1 mile underground?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
What would happen if you drilled to the Earth’s core?
The drill would fail at about 40,000 -45,000 feet (12 -14 km). At that depth you could roast a chicken, and it only gets hotter closer to the mantle. Eventually, magma would erupt through the hole. The hole reached 12,262 m (40,230 ft) in 1989.
What would happen if you drilled a hole through the earth?
With such immense speed, you completely overshoot earth’s center. As you travel through the far end of the hole, gravity is now in the opposite direction and slows you down. You are slowed down to zero speed just as you emerge from the hole on the other side of the world.
