A failed miniature continent lies hidden beneath the sea between Canada and Greenland, scientists have discovered.
The Davis Strait, which separates the two landmasses, ranges from about 200 to 400 miles (320 to 640 kilometers) wide on its path connecting the Labrador Sea and Baffin Bay. It's known to have an oddly thick seafloor, and now researchers know why: The crust is actually a crumb of a continent that didn't fully pull away when Greenland and Canada rifted apart.
