The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres long but has a mean width of only 69 kilometres. It reaches a maximum-known depth of about 10.91 kilometres at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end, although some unrepeated measurements place the deepest portion at 11.03 kilometres. If Mount Everest, the highest mountain on Earth at 8,848 metres, was set in the deepest part of the Mariana Trench, there would be 2,060 metres of water left above it.
