Massive hole discovered under Antarctic ice Trough bigger than Grand Canyon

(Forbes) A giant valley deeper than the Grand Canyon is buried beneath several miles of glacial ice in West Antarctica, according to a new study by British scientists.

The sub-glacial canyon is nearly two miles deep, 200 miles long and 15 miles wide.

“The discovery of this huge trough, and the characterization of the surrounding mountainous landscape, was incredibly serendipitous,” said Dr. Neil Ross, a professor of geology at Newcastle University and the study’s lead author.
