10,994 m (36,070 ft) — The Challenger Deep, located in the Mariana Trench, 250 miles (400 km) southwest of Guam in the Pacific Ocean, is the deepest known point on the planet. It is named after the British survey ship Challenger II, which first surveyed the trench in 1951. The first humans to descend to Challenger Deep were Dr. Jacques Piccard and Dr. Don Walsh aboard the bathyscaphe Trieste (10,911 m / 35,797 ft) in 1960. James Cameron made the first solo descent to the Challenger Deep in 2012, and Victor Vescovo made the deepest dive to the Challenger Deep reaching the seafloor at a depth 10,925 m (35,843 ft) on April 28, 2019.
