Did you know: the deepest hole on Earth?

The deepest hole on Earth" that was permanently sealed after a discovery of 2 billion year old rock formations is called the Kola Superdeep Borehole, located on the Kola Peninsula in Russia; it was drilled by the Soviet Union as part of a scientific research project to study the Earth's crust, and was capped due to safety concerns and the extreme conditions encountered at such depths.
Key points about the Kola Superdeep Borehole:
Depth:
It reached a depth of 12,262 meters (40,230 feet), making it the deepest man-made hole on Earth.
Discovery:
Researchers found extremely old rock formations, estimated to be around 2 billion years old, during the drilling process.
Reason for sealing:
The borehole was eventually sealed due to high temperatures and pressures encountered at such depths, as well as safety concerns.
Scientific significance:
Despite its closure, the Kola Superdeep Borehole provided valuable data about the Earth's crust composition.

Kinda wonder how many people been thrown down in there though before ' sealed' 😳

Ummm. That's not the Borehole..that picture is an open Pit Mine. The Kola Peninsula Borehole is only about a foot in diameter or less even.
@icedsky I did wonder why it was so big.

@NudasPriest I believe that is a picture of the Mir Diamond Mine in Russia
@icedsky @NudasPriest
Part of reason i chose that picture was this video, if y'all care to take time to watch it. The data on the diamond mine and borehole is kinda confusing
