The Kola Superdeep Borehole, an abandoned Cold War attempt by the Soviets to drill to the center of the Earth, stretches a third of the way through the continental crust. Beneath this rusty old metal cap lies some of our world's deepest mysteries. Though it measures just 9 inches in diameter, the hole beneath the cap extends 40,230 feet under the Earth, or 7.5 miles. The Kola Superdeep Borehole was drilled between 1970 and 1994 in a Cold War-era attempt by the Soviets to beat the United States in a race to drill to the center of the Earth — or to get as close to the center as possible.
