The 'Bentley Sub-glacial Trench' is a vast
trench in
Antarctica, 80°S, 115°W. At 2,555 meters (8,383 ft) below
sea level, it is the lowest point on the surface of the earth not covered by ocean, although it is covered by ice. Most people do not count it as the lowest point on land, since the ice makes it essentially subterranean. Also, if the ice melted, the area would be under water. The trench's size is similar to that of
Mexico.
The trench is named after
Charles Bentley, a geophysicist who led many scientific expeditions in Antarctica.
