The deepest point of the Mariana Trench is called The Challenger Deep , so named after the British exploration vessel HMS Challenger II, and it is located 210 miles south-west of Guam. This depth was reached in 1960 by the Trieste, a manned submersible owned by the U.S. Navy.
Descending to the deepest point of the Mariana Trench gave scientists an up-close look at an area where two tectonic plates meet. When James Cameron descended nearly 7 miles (11 kilometers) into the Challenger Deep, he found a world that seemed very, very still.
