Although Russia’s Kola Superdeep Borehole is a mere 9 inches in diameter, its depth is super deep indeed. At 7.5 miles deep, the hole is not only the deepest in the world but it’s deeper than the deepest part of the ocean! – At the site, Soviet geologists made a surprising discovery – evidence of life was detected in the 2 billion-year-old subterranean rock. Due to temps reaching 356 Fahrenheit and melting the research tools and equipment, the hole was bolted shut. However, visitors can make the trip to the remote town of Zapolyarny to view the site and core samples for themselves.
