Massive canyon hidden below Greenland's ice

Scientists using radio waves to estimate the thickness of the ice sheet that covers Greenland found a canyon — more than 2600 feet deep and almost 500 miles long — buried under the ice. Longer than the Grand Canyon, the Greenland canyon hasn't ever been seen by humans. It was probably last completely uncovered 4 million years ago.
