Researchers said the landscape appears to date to at least 14 million years ago and perhaps beyond 34 million years ago, when Antarctica entered its deep freeze.
Wilkes Lands
Wilkes Land is a large district of land in eastern Antarctica, bordering the Indian Ocean.
It is almost entirely covered by the East Antarctic Ice Sheet (EAIS).
Wilkes Land was first sighted in 1838 by the United States Exploring Expedition.
Led by Lieutenant Charles Wilkes.
Wilkes claimed the land for the United States, but his claim was never officially recognized.
Wilkes Land is home to a number of research stations, including the Australian Antarctic Division's Davis Station and the French Polar Institute Paul Emile Victor's Dumont d'Urville Station.
The land is also home to a number of geological features, including the Wilkes Land crater, which is thought to be a giant impact crater.
The Wilkes Land crater is a large, circular structure that is hidden beneath the East Antarctic Ice Sheet.
It is thought to be a giant impact crater, formed when a large asteroid or comet collided with the Earth millions of years ago.
The Wilkes Land crater is one of the largest impact craters on Earth.
It is estimated to be about 500 kilometers (310 miles) in diameter.
