The Kola Superdeep Borehole is a scientific drilling project located on the Kola Peninsula in Russia. Initiated in 1970 by the Soviet Union, the project aimed to explore the Earth's crust and reach deeper into the geological layers than ever before. The borehole reached its maximum depth of 12,262 meters (40,230 feet) in 1989, making it the deepest artificial point on Earth.
