What is the deepest point on Earth?
Quick Answer
The Challenger Deep in the Mariana Trench reaches 11,034 meters (36,201 feet) below sea level — deeper than Mount Everest is tall. Only three crewed descents have reached the bottom.
The Full Story
The Challenger Deep, located in the Mariana Trench in the western Pacific Ocean, is the deepest known point on Earth at approximately 11,034 meters (36,201 feet) below sea level. If Mount Everest were placed at the bottom, its peak would still be over 2 km underwater. Pressure at this depth exceeds 1,000 atmospheres (about 15,750 psi). The first crewed descent was in 1960 by Jacques Piccard and Don Walsh in the bathyscaphe Trieste. In 2012, filmmaker James Cameron made a solo dive. In 2019, Victor Vescovo reached 10,928 m in the DSV Limiting Factor. Despite the extreme conditions, life has been found at the bottom, including amphipods and xenophyophores.
