Massive canyon found under Antarctic ice

A huge subglacial trench deeper than the Grand Canyon has been discovered hidden beneath the Antarctic.
The discovery was made by a team of scientists who had been charting an ancient mountain range located deep below the ice known as the Ellsworth Subglacial Highlands.

Using a combination of ground-penetrating radar and satellite imagery they were able to build up a picture of the continent's long lost topography.

The giant trench is believed to go down over 1.9 miles which makes it deeper than the Grand Canyon's 1.13 miles. It is thought that this new Antarctic canyon was initially formed by an ancient river running through a geological fault, then widened over the years by glaciation.

"It's a huge privilege to be able to reveal another piece of the jigsaw puzzle that is the surface of our Earth," said geophysicist Neil Ross who lead the study team.

Could the missing islands be explained by the possibility that the sea levels may heve been different at the time the map was made? Just a thought.

Very unlikely. The map is impressively accurate in showing what was known by European sailors by around 1515: it shows the Caribbean, the northern part of South America, Africa and Spain very well. Beyond that it gets really wobbly. For example South America curves around into "Antarctica" way too far north - seemingly just south of the Plate River estuary. Another problem with it showing Antarctica is that notes in that part of the map apparently talk about that land's warm climate and the presence of snakes. If that's supposed to be accurate, then presumably Piri Reis w... [More]

I never really got why people are so amazed by the Piri Reis map. Like Peter B said, Europe and the Carribean and the eastern parts of Brazil are fairly accurate, but the rest of South America is basically made up, and so is North and Central America. If this is a depiction of antarctica where is the Strait of Magellan ? Seems like a very significant omission. And it shows people with faces in their stomach

Piri died in 1553. Sea levels were a little lower then, but not much. Doug

The maps are believed to date from about 1515. Magellan didn't discover the Straits of Magellan until 1520. Doug

That doesent change the fact that it was still there. You cant have an accurate map of Antarctica without a strait betweeen it and South America.

It's sort of hard to map something you don't know is there. Doug

I thought the op said A Massive Canon......

I know the Magellan Strait wasnt discovered yet in the time of Piri Reis, and my point is that it only shows accurately what was known at the time, the rest is guess work. What i meant was, if someone supposedly knew how Antartica looked witout ice, wouldnt they also have know about the strait between Antartica and South America ?
