The greatest canyon in the world hiding under the ice in Antarctica?

A large canyon system and lake have been discovered beneath the ice of the Antarctic continent, according to observations from satellites.

The canyon system , which runs over 1,000km and has a depth of up to 1km, is located in an area difficult to show on the map, the Elizabethan Land (Princess Elizabeth Land) in East Antarctica. It has a length far beyond the Great Canyon (Grand Canyon) in the US with a length of 446km. This finding has just been published in the Journal of Geology (UK).

"Our analysis shows that there is evidence of the existence of a large canyon and possibly a lake underneath the ice of Princess Elizabeth's Land. It is surprising that they have only been released until now. " - researcher Stewart Jamieson of the Department of Geology at Durham University (UK), said.

"This is an area even bigger than the UK, and we still know very little about what lies beneath the ice. In fact, what we know about the bottom of Antarctica is less than what it belongs to. "If we know more about the landscape buried under the ice, we will better understand how the ice sheets react to climate changes," he said. .

The researchers believe that this canyon system has been created by water and has existed before the Antarctic ice sheet was formed, or created by running water beneath the ice, eroding the rock mass. .

Currently, the research team is conducting measurements of the entire area. Specific results will be announced in 2016.
