A major feature of the Earth has escaped notice — until now.
Scientists Thursday that they’ve discovered a vast canyon, twice as long as the Grand Canyon. It carves a deep scar from the center of the world’s largest island out to the coast. And, oh one more detail: It’s buried beneath as much as 2 miles of ice.

Hidden for all of human history, a 460 mile long canyon has been discovered below Greenland’s ice sheet. Using radar data from NASA’s Operation IceBridge and other airborne campaigns, scientists led by a team from the University of Bristol found the canyon runs from near the center of the island northward to the fjord of the Petermann Glacier.
