The Kola Superdeep Borehole is a decommissioned Russian scientific drilling site located near the Russia-Norway border. The project's primary purpose was to drill as deep as possible into the Earth's crust, eventually reaching a record-setting 12,262 meters depth. As of 2024, the Kola Superdeep Borehole remains the deepest human-made hole on Earth. #ScienceChannel #MysteriesOfTheAbandoned | Science Channel
