  Original Published: 9/3/2013 Scientists, with help from NASA radar imaging, say they've found a new Grand Canyon in Greenland. The Mega-Canyon was hidden under a massive sheet of ice. Scientists from the University of Bristol say the canyon is 460 miles long, almost 200 miles longer than the Grand Canyon in Arizona. But the Mega-Canyon isn't nearly as deep, although in some places, it is as deep as 2,600 feet. Researchers believe it's been hidden for four-million years. Using rada data from NASA's Operation IceBridge, scientists found the canyon runs from near the center of the island, northward to the fjord of the Petermann Glacier. The researchers believe the canyon plays an important role in transporting sub-glacial meltwater from the interior of Greenland to the edge of the ice sheet into the ocean.
