The Bentley Sub-glacial Trench is a vast oceanic trench in Antarctica, 80°S, 115°W. At 2,555 meters (8,327 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.

The Bentley Sub-glacial Trench is a vast oceanic trench in Antarctica, 80°S, 115°W. At 2,555 meters (8,327 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.This is the lowest trench below sea level in Antartica.
The trench is named after Charles Bentley in 1961, who was the geophysicist and led the scientific expedition in Antarctica in 1957-58 that led to its discovery.
