World’s Largest Canyon Could Lie Under Antarctic Ice
A canyon system potentially bigger than the Grand Canyon in the U.S. could be hiding beneath the Antarctic ice sheet, measuring 1,000km long and as much as 1km deep. Researchers from Durham University and Imperial College London – along with American, Australian, Indian, and Chinese scientists studying satellite data, think that a massive canyon system could be hidden underneath a largely unexplored region of the Antarctic, called Princess Elizabeth Land. The study is being verified by a geological survey, which is now under way.
